Load Tolerance
3 : Constant Torque 100:1 SpeedRange
Use this setting for vector motors with a speed range for constant torque of 1:100.
The speed control for this motor is 1% to 100% when at 100% load. Operating slower than 1%
speed at 100% load will cause motor overload.
Load Tolerance
4 : PM Variable Torque
Use this setting for PM motors with derated torque characteristics.
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.

Overload Characteristics
(at 100% motor load)
The motor operates continuously at
10% to 100% base frequency.
Operating slower than 10% speed at
100% load will cause motor overload.
Overload Characteristics
(at 100% motor load)
The motor operates continuously at 1%
to 100% base frequency. Operating
slower than 1% speed at 100% load
will cause motor overload.
Overload Characteristics
(at 100% motor load)
If the motor operates continuously at
lower speed than rated rotation speed at
more than 100% torque, the drive will
detect oL1. The drive triggers a fault
relay output and the motor coasts to
stop.
