Protection Design IP20 open-chassis, NEMA Type 1 enclosure

Speed control accuracy may vary slightly depending on installation conditions or motor used.

Momentary average deceleration torque refers to the deceleration torque from 60Hz down to 0 Hz. This may vary depending on the motor.

If L3-04 is enabled when using a braking resistor or braking resistor unit, the motor may not stop within the speciﬁ ed deceleration time.

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

Varies by drive capacity. Drives smaller than 7.5 kW (CIMR-VA2A0004/CIMR-VA4A0023) require a separate Momentary Power Loss Recovery Unit to continue operating during a momentary power loss of 2 s.

Protection may not be provided under the following conditions as the motor windings are grounded internally during run:

• Low resistance to ground from the motor cable or terminal block.

• Drive already has a short-circuit when the power is turned on.

Rotational Auto-Tuning must be performed to achieve the performance described with Open Loop Vector Control.
