*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.
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.
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.
