MxC Application Precautions
This section provides precautions for selecting, installing, setting, and handling MxCs.
Selection
Observe the following precautions in selecting an MxC.
Reduction Ratio of Carrier Frequency, Control Method, and Rated Current
The following table shows the reduction ratio of the carrier frequency, control methods, and rated current.
Model: CIMR-ACA25P5, 2011, 2022, 45P5, and 4011
Model: CIMR-ACA2045, 4045, and 4075
Model: CIMR-ACA4022
Models: CIMR-ACA4110 and 4160
Note: 100% indicates the rated current value when the carrier frequency is 4 kHz.
When Momentary Power Loss Ridethrough Time Needs 2 Seconds or More
If the CIMR-ACA45P5, 4011, 25P5, 2011, or 2022 needs two seconds or more for the momentary power loss
ridethrough time, a momentary-power-loss compensation unit is necessary. If L2-01 (Momentary Power Loss
Detection Selection) is enabled, the MxC will stop 2 ms after the momentary power loss occurs. Be aware of
these differences and select appropriately for your application needs.
• 200 V class momentary power loss compensation unit: Code no. 73600-P0010
• 400 V class momentary power loss compensation unit: Code no. 73600-P0020
