Protection Design

*1: Requires a drive with recommended capacity.

*2: Speed control accuracy may vary slightly depending on installation conditions or motor used. Contact Yaskawa for details.

*3: Instantaneous average deceleration torque refers to the torque required to decelerate the motor (uncoupled from the load) from the rated motor speed down to zero in the shortest time.

*4: If L3-04 is enabled when using a braking resistor or braking resistor unit, the motor may not stop within the speciﬁed deceleration time.

*5: Overload protection may be triggered at lower levels if output frequency is below 6 Hz.

*6:

Varies in accordance with drive capacity and load. Drives with a capacity of smaller than 11 kW in the 200 V (model: CIMR-AC2A0056) or 400 V (model: CIMR-AC4A0031) require a separate Momentary Power Loss Recovery Unit to continue operating

during a momentary power loss of 2 s or longer.

*7:

Ground protection cannot be provided when the impedance of the ground fault path is too low, or when the drive is powered up while a ground fault is present at the output.
