Select the start function.
Setting 11.01 START MODE
purpose start function. This setting also makes flying start (starting to
a rotating motor) possible.
The highest possible starting torque is achieved when
MODE is set to (0) Fast
Const time (constant DC magnetising with user-defined magnetising
time).
Note: When 11.01 START MODE
flying start (start to a rotating motor) is not possible.
Set the operation limits according to the process requirements.
Note: If load torque is suddenly lost when the drive is operating in
torque control mode, the drive will rush to the defined negative or
positive maximum speed. For safe operation, ensure the set limits are
suitable for your application.
Set the alarm and fault limits for the motor overtemperature protection.
Set the typical ambient temperature of the motor.
When 45.02 MOT TEMP SOURCE
motor thermal protection model must be configured as follows:
- Set the maximum allowed operating load of the motor.
- Set the zero speed load. A higher value can be used if the motor has
an external motor fan to boost the cooling.
- Set the break point frequency of the motor load curve.
- Set the motor nominal temperature rise.
- Set the time inside which the temperature has reached 63% of the
nominal temperature.
If possible, perform the motor ID run again at this point (see page 20).
