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
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 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.
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 Constant Torque
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 : Variable Torque (50Hz)
Use this setting for general-purpose motors with a 50 Hz base frequency.
