DRIvE SETTINGS
You must ensure that the drive parameters
are set correctly to give adequate thermal
protection to the motor. Please refer to the
motor label when setting the limits for the
drive. The value of the drive parameters will
vary with each type of motor.
Incorrect setting of the current and thermal
time constant (4.15) could cause the motor
to overheat and invalidate the warranty.
