3 : Vector Motor (Constant Torque Range 1 : 100)
The motor is allowed to run with 100% load from 1% to 100% speed. When the motor runs
slower with 100% load, an overload fault will be triggered.

P1-01 Motor Overload Protection Time
Sets the time for the drive to shut down on motor overload. (Normal this parameter does not
require adjustment. However, enter the time the motor can withstand operation in a hot motor
overload condition if the motor overload tolerance data is confirmed by the motor
manufacturer.)
Motor Overload Protection Time
The default is operation with 150% overload tolerance for one minute in a hot start.
The electrothermal protection operation time is illustrated in the following figure. Motor
overload protection operates in the range between a cold start and a hot start.
