24 **Connect the main circuit power supply**
25
26 After power on the main circuit, the bus voltage indicator shows no abnormality, and the panel display "rdy", indicating that the servo drive is in an operational state, waiting for the host computer to give the servo enable signal.
27
28 If the drive panel displays other fault codes, please refer to __[[“10 Malfunctions">>doc:Servo.Manual.02 VD2 SA Series.10 Malfunctions.WebHome]]__” to analyze and eliminate the cause of the fault.

31
32 == Jog operation ==
33
34 Jog operation is used to judge whether the servo motor can rotate normally, and whether there is abnormal vibration and abnormal sound during rotation. Jog operation can be realized in two ways, one is panel jog operation, which can be realized by pressing the buttons on the servo panel. The other is jog operation through the host computer debugging platform.
35
36 **Panel jog operation**
37
38 Enter “P10-01” by pressing the key on the panel. After pressing “OK”, the panel will display the current jog speed. At this time, you can adjust the jog speed by pressing the "up" or "down" keys; After adjusting the moving speed, press "OK", and the panel displays "JOG" and is in a flashing state. Press "OK" again to enter the jog operation mode (the motor is now powered on!). Long press the "up" and "down" keys to achieve the forward and reverse rotation of the motor. Press "Mode" key to exit the jog operation mode. For operation and display, please refer to __[["5.3.2. Jog operation">>https://docs.we-con.com.cn/bin/view/Servo/Manual/02%20VD2%20SA%20Series/05%20Panel/#HJogoperation]]__.
39
40 **Jog operation of servo debugging platform**
41
42 Open the jog operation interface of the software “Wecon SCTool”, set the jog speed value in the "set speed" in the "manual operation", click the "servo on" button on the interface, and then achieve the jog forward and reverse function through the "forward rotation" or "Reverse" button on the interface. After clicking the "Servo off" button, the jog operation mode is exited. The related function codes are shown below.

96 == **Braking resistor** ==
97
98 The servo motor is in the generator state when decelerating or stopping, the motor will transfer energy back to the drive, which will increase the bus voltage. When the bus voltage exceeds the braking point, The drive can consume the feedback energy in the form of thermal energy through the braking resistor. The braking resistor can be built-in or externally connected, but it cannot be used at the same time. When selecting an external braking resistor, it is necessary to remove the short link on the servo drive.
99
100 The basis for judging whether the braking resistor is built-in or external.
101
102 1. the maximum brake energy calculated value > the maximum brake energy absorbed by capacitor, and the brake power calculated value ≤ the built-in braking resistor power, use the built-in braking resistor.
103 1. the maximum brake energy calculated value > the maximum brake energy absorbed by capacitor, and the brake power calculated value > the built-in braking resistor power, use external braking resistor.

140
141 The servo drive is in a running state and displays "run", but because there is no instruction input at this time, the servo motor does not rotate and is locked.
142
143 S-ON can be configured and selected by the DI terminal function selection of the function code "DIDO configuration".
144
145 **Input the instruction and the motor rotates**
146
147 Input appropriate instructions during operation, first run the motor at a low speed, and observe the rotation to see if it conforms to the set rotation direction. Observe the actual running speed, bus voltage and other parameters of the motor through the host computer debugging platform. According to [[__"7 Adjustment"__>>doc:Servo.Manual.02 VD2 SA Series.07 Adjustments.WebHome]], the motor could work as expected.

199 **Emergency shutdown**
200
201 It is free shutdown mode at present, and the motor shaft remains in a free state. The corresponding configuration and selection could be selected through the DI terminal function of the function code "DIDO configuration". The V1.18 firmware version adds the Estop stop time setting function. In some occasions where the servo needs to control the emergency stop of the motor, it is necessary to control the emergency stop time of the DI. Therefore, the P01-05 shutdown deceleration time function is added to deal with this situation.
202
203 Estop mode 1 (deceleration stop):
204
205 ~1. Configurate DI function code: 8 [ESTOP]
206
207 2. Set P1-5 shutdown deceleration time.
208
209 3. Trigger DI emergency shutdown.
210
211 4. Servo emergency shutdown and deceleration to zero speed.
212
213 Estop mode 2:
214
215 ~1. Configurate DI function code: 1 [Servo enable SON]
216
217 2. Set P1-05 shutdown deceleration time.
218
219 3. Set P0-05 Servo OFF shutdown mode: zero speed stop.

241
242 **Overtravel shutdown**
243
244 Overtravel means that the movable part of the machine exceeds the set area. In some occasions where the servo moves horizontally or vertically, it is necessary to limit the movement range of the workpiece. The overtravel is generally detected by limit switches, photoelectric switches or the multi-turn position of the encoder, that is, hardware overtravel or software overtravel.
245
246 Once the servo drive detects the action of the limit switch signal, it will immediately force the speed in the current direction of rotation to 0 to prevent it from continuing, and it will not be affected for reverse rotation. The overtravel shutdonw is fixed at zero speed and the motor shaft remains locked.
247
248 The corresponding configuration and selection could be selected through the DI terminal function of the function code "DIDO configuration". The default function of DI3 is POT and DI4 is NOT, as shown in the table below.

565 Position control is the most important and commonly used control mode of the servo system. Position control refers to controlling the position of the motor through position instructions, and determining the target position of the motor by the total number of position instructions. The frequency of the position instruction determines the motor rotation speed. The servo drive can achieve fast and accurate control of the position and speed of the machine. Therefore, the position control mode is mainly used for occasions that require positioning control, such as manipulators, mounter, engraving machines, CNC machine tools, etc. The position control block diagram is shown in the figure below.

943 VD2 series servo drive has three multi-segment position running modes, and you could select the best running mode according to the site requirements.
944
945 1. Single running
946
947 In this running mode, the segment number is automatically incremented and switched, and the servo drive only operates for one round (the servo drive runs completely once for the total number of multi-segment position instructions set by P07-02 and P07-03).

1149 **Definition of electronic gear ratio**
1150
1151 In the position control mode, the input position instruction (instruction unit) is to set the load displacement, and the motor position instruction (encoder unit) is to set the motor displacement, in order to establish the proportional relationship between the motor position instruction and the input position instruction, electronic gear ratio function is used. "instruction unit" refers to the minimum resolvable value input from the control device(HMI/PLC) to the servo drive. "Encoder unit" refers to the value of the input instruction processed by the electronic gear ratio.
1152
1153 With the function of the frequency division (electronic gear ratio <1) or multiplication (electronic gear ratio > 1) of the electronic gear ratio, the actual the motor rotation or movement displacement can be set when the input position instruction is 1 instruction unit.
1154
1155 It it noted that the electronic gear ratio setting range of the 2500-line incremental encoder should meet the formula (6-1), and the electronic gear ratio setting range of the 17-bit encoder should meet the formula (6-2), setting range of the electronic gear ratio of 23-bit encoder should meet the formula (6-3)

1266 == Position instruction filtering ==
1267
1268 Position instruction filtering is to filter the position instruction (encoder unit) after the electronic gear ratio frequency division or frequency multiplication, including first-order low-pass filtering and average filtering operation.
1269
1270 In the following situations, position instruction filtering should be added.
1271
1272 1. The position instruction output by host computer has not been processed with acceleration or deceleration;
1273 1. The pulse instruction frequency is low;
1274 1. When the electronic gear ratio is 10 times or more.
1275
1276 Reasonable setting of the position loop filter time constant can operate the motor more smoothly, so that the motor speed will not overshoot before reaching the stable point. This setting has no effect on the number of instruction pulses. The filter time is not as long as possible. If the filter time is longer, the delay time will be longer too, and the response time will be correspondingly longer. It is an illustration of several kinds of position filtering.

1321 the positioning completion function means that when the position deviation meets the value set by P05-12, it could be considered that the positioning is complete in position control mode.

1383 **(2) Pulse signal DO output function of VD2L-0xxSA1P**
1384
1385 The pulse signal of VD2L-0xxSA1P is the collector signal output by DO, and it can be connected to the high-speed pulse input of PLC without the conversion of differential to collector circuit board.
1386
1387 **(3) The difference of collector pulse signal DO Function of VD2-0xxSA1H and DO output function of pulse signal of VD2L-0xxSA1P**

2408 Absolute encoder could detect the position of the servo motor within one turn, and could count the number of turns of the motor. This series of servo drives are equipped with a maximum of 23-bit encoders and could memorize 16-bit multi-turn data, and position, speed, torque control modes could be used. Especially in position control, the absolute value encoder does not need to count, could achieve direct internal high-speed reading and external output, and could significantly reduce the subsequent calculation tasks of the receiving device controller. When the drive is powered off, the encoder uses battery backup data. After power on, the drive uses the encoder's absolute position to calculate the absolute mechanical position, eliminating the need for repeated mechanical origin reset operations.
2409
2410 The absolute value encoder is determined by the mechanical position of the photoelectric code disc, and is not affected by power failure or interference. Each position of the absolute encoder determined by the mechanical position is unique, and no external sensor is required to assist in memorizing position.
2411
2412 == Single-turn absolute value system ==
2413
2414 The single-turn absolute value system is applicable for the equipment load stroke within the single-turn range of the encoder. At this time, the absolute encoder is only as a single-turn system function and does not need to be connected to the battery. The types and information of encoders adapted to VD2 series servo drives are shown as below.

The multi-turn absolute encoder is equipped with a battery (the battery is installed on the encoder cable with a battery unit), which can achieve direct internal high-speed readings and external output without the need for external sensors to assist memory positions.
