486 -
487 -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.
488 -
489 -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.
490 -
491 -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.
492 -
493 -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;
