Running the motor

For information on tuning of the drive for best performance please refer to the Running
the motor and optimization section of the Unidrive SP User Guide.
Ensure that no damage or safety hazard could arise from the motor starting
unexpectedly.
WARNING
The values of the motor parameters affect the protection of the motor.The default
values in the drive should not be relied upon. It is essential that the correct value is
entered in Pr 0.46 Motor rated current. This affects the thermal protection of the motor.
CAUTION
If the keypad mode has been used previously, ensure that the keypad reference has
been set to 0 using the
run to the speed defined by the keypad reference (Pr 0.35).
CAUTION
If the intended maximum speed affects the safety of the machinery, additional
independent over-speed protection must be used.
WARNING
4.9.1 Autotuning
In order for the drive to obtain the correct motor parameter values, the autotune should
be carried out when operating from a normal high voltage supply and not when in Low
Voltage DC operation. If it is not possible to autotune the drive when operating from a
normal high voltage supply the motor parameters should be obtained from the motor
nameplate and entered into the drive manually.
