450 +* Role of removing EMC screws: When the grounding of the whole equipment system is unstable, it is easy for the interference signal to enter the input terminal of the VFD, which leads to the inaccurate operation of the terminal motor, and then it is necessary to remove the EMC screws on the machine in order to solve the influence of external interference.

464 +Torque mode can only be vector control, torque control refers to the strength, that in the torque mode F0.03 is the default value, modify F0.03 for other values is invalid.
465 +
466 +Debugging ideas:
467 +
468 +~1. According to the application requirements of the torque command and the upper limit of the frequency.
469 +
470 +2. Set the frequency acceleration/deceleration time F0.18/F0.19 and the torque acceleration/deceleration time F3.14/F3.15, the torque acceleration/deceleration time is less than or equal to the frequency acceleration/deceleration time.
471 +
472 +3. Start the motor and observe whether the motor can run or not, if it can't run normally, rotate the motor with external force, if it can be started, it is judged to be necessary to increase the static friction coefficient compensation.
473 +
474 +4. After the motor is running, observe the motor running state, if the motor is blocked, check whether it is shaking when it is blocked, if it is shaking, increase F3.07, generally 0.01 amplitude increment.
475 +
476 +5. When the torque command F3.10 is lower than the percentage of "no-load current / rated current", the running frequency is about: rated frequency * torque command percentage * rated current / no-load current.
477 +
478 +6. Static Friction Compensation Logic: During startup, the torque command 1 = F3.11* F3.24 /100 is passed to the performance; after a maintenance time of F3.25 seconds, it reverts to torque command 2 = F3.11; the switching of torque commands 1 /2 occurs through the torque acceleration and deceleration times F3.14 / F3.15;
479 +
480 +7. Auxiliary debugging parameters: filter coefficient F3.07 and static friction compensation F3.24/ F3.25.
