How to improve speed precision of YASKAWA CIMR-JT Controller?
- AAmanda AlvaradoAug 9, 2025
After setting the motor-rated current (E2-01), motor-rated slip (E2-02) and motor no-load current (E2-03), adjust the slip compensation gain (C3-01).
How to improve speed precision of YASKAWA CIMR-JT Controller?
After setting the motor-rated current (E2-01), motor-rated slip (E2-02) and motor no-load current (E2-03), adjust the slip compensation gain (C3-01).
What to do if YASKAWA Controller motor has poor torque at low speeds and motor instability at start?
If the torque is insufficient at speeds below 10 Hz, increase the setting. If motor instability occurs at motor start, decrease the setting.
What to do if YASKAWA CIMR-JT motor has poor motor torque at speeds below 10 Hz and motor hunting?
If motor torque is insufficient at speeds below 10 Hz, increase the setting. If motor hunting and oscillation occur with a relatively light load, decrease the setting.
How to fix YASKAWA CIMR-JT Controller motor noise, hunting and oscillation at speeds up to 40 Hz?
If the motor noise is too loud, increase the carrier frequency. When motor hunting and oscillation occur at speeds up to 40 Hz, lower the carrier frequency.
