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 Cooling Capability
Overload Characteristics
(at 100% motor load)
This motor is designed to withstand increased
temperatures during continuous operation in the low
speed range (1% base frequency).
The motor operates continuously at 1% to 100% base
frequency. Operating slower than 1% speed at 100% load
will cause motor overload.
4 : PM VTorque
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.
Load Tolerance Cooling Capability
Overload Characteristics
(at 100% motor load)
This motor is designed to withstand increased
temperatures during continuous operation at rated speed
and rated torque.
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.
5 : PM CTorque
Use this setting with a PM motor for constant torque that has a speed range for constant torque of 1:500.
The speed control for this motor is 0.2% to 100% when at 100% load. Operating slower than 0.2% speed at 100%
load will cause motor overload.
Load Tolerance Cooling Capability
Overload Characteristics
(at 100% motor load)
This motor is designed to withstand increased
temperatures during continuous operation in the low
speed range (0.2% base frequency).
The motor operates continuously at 0.2% to 100% rated
speed. Operating slower than 0.2% speed at 100% load
will cause motor overload.
6 : VT (50Hz)
Use this setting for general-purpose motors with a 50 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.
