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
