Specifications 1 2 : : Under development. The maximum applicable motor output is given for a standard 4- pole Yaskawa motor. When selecting the actual motor and MxC, be sure that the MxC’s rated current is applicable for the motor's rated current. The rated current will vary in accordance with the values of the voltage or impedance of the power supply (including the power transformer, the input reactor, and wires). Required to reduce the rated output current in accordance with the values of the carrier frequencies or control mode. Rotational autotuning must be performed to ensure obtaining the specifications given for open - loop or flux vector control.
The speed control accuracy depends on the installation conditions and type of motor used. Contact your Yaskawa representative for details. Applications with repetitive loads may require derating (reducing carrier frequency and current, which involves increasing the frame size of the MxC). Contact your Yaskawa representative for details. If the CIMR - ACA 25 P 5 , 2011 , 2022 , 45 P 5 , or 4011 needs two seconds or more for the momentary power loss ridethru time, a back-up capacitor unit for momentary power loss is necessary. If L 2-01 (Momentary Power Loss Detection Selection) is enabled, the MxC will stop 2 ms after the momentary power loss occurs.
Contact your Yaskawa representative for details about use in applications, such as trolley cranes, with a tendency to have momentary power losses or open phases. The ground fault here is one which occurs in the motor wiring while the motor is running. A ground fault may not be detected in the following cases. A ground fault with low resistance which occurs in motor cables or terminals. A ground fault occurs when the power is turned on. 3 4 5 6 7 : : : : : 8 : 10 9 : Voltage Class 200 V 400 V Model Number CIMR-ACA 25P5 2011 2022 2045 1 45P5 4011 4022 4045 1 4075 1 Max.
