[. . . ] Be sure to restore covers or shields before operating the Units and run the Units according to the instructions described in this manual. · Any illustrations, photographs, or examples used in this manual are provided as examples only and may not apply to all products to which this manual is applicable. · The products and specifications described in this manual or the content and presentation of the manual may be changed without notice to improve the product and/or the manual. · When ordering a new copy of the manual due to damage or loss, contact your Yaskawa representatives or the nearest Yaskawa sales office and provide the manual number shown on the front cover. [. . . ] Adjust in the following circumstances: · When the motor is oscillating, increase the set values. · When the responsiveness of the motor is low, decrease the set values. 0. 00 to 2. 50 1. 00 Yes A A A No No C4-02 Torq Comp Time 0 to 10000 20 ms * No A A A No No * The factory setting will change when the control method is changed. (Open-loop vector 1 factory settings are given. ) Adjusting Torque Compensation Gain Normally, there is no need to make this adjustment. Do not adjust the torque compensation gain when using open-loop vector control. Adjust the torque compensation gain using V/f control in the following circumstances. · If the cable is very long, increase the set value. · If the (maximum applicable) motor capacity is smaller than the Inverter capacity, increase the set value. · If the motor is vibrating, reduce the set value. Adjust this constant so that the output current during low-speed rotation does not exceed the Inverter rated output current range. Adjusting the Torque Compensation Primary Delay Time Constant Set the torque compensation function primary delay in ms. You can switch the factory settings as follows by changing the control method settings: · V/f control without PG: 200 ms · V/f control with PG: 200 ms · Open-loop vector control: 20 ms 6-35 Normally, there is no need to make this setting. Adjust the constant as shown below. · If the motor is vibrating, increase the set value. · If the motor response is low, decrease the set value. Hunting-prevention Function The hunting-prevention function suppresses hunting when the motor is operating with a light load. This function can be used in V/f without PG and V/f with PG.

(Use the following values as guidelines. ) Wiring Length C6-02 (carrier frequency selection) setting 50 m or less 1 to 6 (15 kHz) 100 m or less 1 to 4 (10 kHz) Over 100 m 1 to 2 (5 kHz) If speed and torque are inconsistent at low speeds: Set the carrier frequency low. If leakage current from the Inverter is large: Set the carrier frequency low. If metallic noise from the motor is large: Set the carrier frequency high. · When using V/f control or V/f control with PG, you can vary the carrier frequency according to the output frequency, as shown in the following diagram, by setting C6-03 (Carrier Frequency Upper Limit), C6-04 (Carrier Frequency Lower Limit), and C6-05 (Carrier Frequency Proportional Gain). 6-39 Carrier Frequency C6-03 C6-04 Output frequency × C6-05 × K* * K is the coefficient determined by the set value in C6-03. C6-03 10. 0 kHz: K=3 10. 0 kHz > C6-03 5. 0 kHz: K=2 5. 0 kHz > C6-03: K=1 Output frequency E1-04 Max. Output Frequency Fig 6. 32 · With vector control, the carrier frequency is fixed to the Carrier Frequency Upper Limit in C6-03 if user- set or by the carrier frequency set in C6-02. · To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0. · If the settings are as shown below, OPE11 (Constant setting error) will occur. If Carrier Frequency Proportional Gain (C6-05) > 6 and C6-03 < C6-04. · Depending on the carrier frequency setting, the Inverter's overload level may be reduced. Even when the overload current falls to below 150%, OL2 (Inverter overload) will be detected. The Inverter overload current reduction level is shown below. Overload reduction level 100% 80% 200 V, 22 200V22kWkW 50% 0 10kHz 15kHz Carrier frequency Fig 6. 33 Overload Reduction Level for V/f Control, V/f Control with PG, Open-loop Vector Control 1, and Flux Vector Control Overload reduction level 100% 87% 200 V, 30 to 75 kW 50% 0 4kHz 8kHz Carrier frequency Fig 6. 34 Overload Reduction Level for Open-loop Vector Control 2 6-40 Machine Protection Limiting Motor Torque (Torque Limit Function) The motor torque limit function is enabled only with open-loop torque control. In the open-loop vector control method, the user-set value is applied to the torque limit by calculating internally the torque output by the motor. Enable this function if you do not want a torque above a specified amount to be applied to the load, or if you do not want a regeneration value above a specified amount to occur.
