is higher than the drive amp rating, set L1-01 =0 [Motor Overload (oL1) Protection = Disabled] and install
thermal overload relays for each motor. The electronic thermal protection of the drive will not function and
it can cause damage to the motor.
1 : Variable Torque
Use this setting for general-purpose motors with a 60 Hz base frequency.
The overload tolerance decreases as motor speed decreases because the cooling fan speed
decreases and the ability of the motor to cool decreases in the low speed range.
The overload tolerance characteristics of the motor change the trigger point for the
electronic thermal protector. This provides motor overheat protection from low speed to
high speed across the full speed range.

Drive
If the motor operates at frequencies
less than 60 Hz, the drive will detect
oL1. The drive triggers a fault relay
output and the motor coasts to stop.
