* 1. The maximum applicable motor capacity is given for a standard, four-pole Yaskawa motor. When selecting the actual motor and MxC, be sure that the MxC’s

rated current is greater than the motor’s rated current.

* 2. 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).

* 3. Required to reduce the rated output current in accordance with the values of the carrier frequencies or control mode.
* 4. Rotational Auto-Tuning is required for the open loop vector or Flux Vector Control.
* 5. The speed control accuracy varies in accordance with the installation condition and motor type. For more details, contact your Yaskawa representative.
* 6. Derating is required for applications that use repetitive loads. To decrease the carrier frequency or to gradually decrease the current, use an MxC with a greater

capacity. For more details, contact your Yaskawa representative.

* 7. If the CIMR-ACA45P5, 4011, 25P5, 2011, or 2022 needs two seconds or more for the momentary power loss ridethrough time, a separate momentary-power-loss

compensation unit is required. Even if the Momentary Power Loss Detection function (L2-01) is enabled, the MxC will run for 2 ms and then stop if a momentary

power loss occurs. Take note of this delay when the MxC is used in various applications.

* 8. 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.

y A ground fault with low resistance which occurs in motor cables or terminals.

y A ground fault occurs when the power is turned on.

* 9. The open chassis is the only type of protective structure available for the MxC models CIMR-ACA4110 and 4160.

Overvoltage protection

Input voltage: Stops if input
power supply voltage is greater
than approx. 250 VAC.

Input voltage: Stops if input power supply voltage is
greater than approx. 550 VAC.

Undervoltage protection
