User Manual EM303B General Purpose Inverter Carrier frequency is set by F0-14. See 7.1 for the description of carrier frequency. Carrier frequency can reduce the electromagnetic noise of motor on premise of not increasing the electric loss of inverter. There are 2 automatic PMW modes for EM-series inverters which can be selected based on the motor power and mechanic devices. Upgrading Running Performance 8.9.5 Open Loop Slip Compensation The speed of motor rotor decreases as load increases. In order to ensure that the speed of rotor is close to synchronous speed, motor could start slip frequency when motor is on rated load.
When the speed of motor is lower than the objective value, increase the setting value of F3-30. F3-30 = 0 Slip compensation is disabled. F7-24 sets the filter time of slip signal if slip compensation is enabled. If the filter time is too little, it will result in system running unstably, and if the filter time is too much, it will cause compensation responding slowly. 8.9.6 Stator Voltagedrop Compensation Gain F7-25 is for compensating the voltagedrop generated by stator resistance and cable. 8.9.7 Deadband Compensation Gain Users do not need to edit F7-26 on general conditions. 8.9.8 Limit Control F7-29 If the setting frequency of inverter does not output.
