How to display motor speed in VB series?
1.Motor speed calibration
| F7.06 | Load speed display coefficien | Default | 0.3000 | |||||
| Setting range | 0.0001~6.5000 | |||||||
Correspond the output frequency of the inverter to the load speed through this parameter. Set when you need to display the load speed.
The default value of this parameter 0.3, corresponds to 1500 rpm. The parameter is calculated by dividing the rated speed of the motor by 1500 and multiplying by 0.3, and setting the calculated value to F7.06.
For example：
- The rated speed of the motor is 2800r/min.
- 2800/1500*0.3=0.56
- Setting 0.56 to F7.06
2.Display motor speed in the VB's LCD
| F7.03 | LED display parameters 1 while running | Default | 17 | ||||||
| Setting range | 0000 ~FFFF | Bit00: Running frequency (Hz) Bit01: Set frequency (Hz) Bit02: DC bus voltage (V) Bit03: Output voltage (V) Bit04: Output current (A) Bit05: Output power (kW) Bit06: Output torque (%) Bit07: DI input status Bit08: DO output status Bit09: AI1 power (V) Bit10: AI2 power (V) Bit11: Reserved Bit12: Count value Bit13: Length value Bit14: Load speed display Bit15: PID set value If you need to display the above parameters while running, set the corresponding digit to 1, convert this binary number to hexadecimal and set it to F7.03. | |||||||
Enable parameter: Bit14: Load speed display.(F7.03=4013)
After starting the inverter use the shift key in the lower left corner of the keyboard to toggle the value displayed in the LCD.
3.Display motor speed in the HMI
HMI setting and project download
| Load speed | 100FH | 1rpm | Read |
100F is a hexadecimal address, which needs to be converted to a decimal address in the HMI 4111
