99.13 IDRUN MODE
Selects the type of the motor identification performed at the next start of the drive in DTC mode.
During the identification, the drive will identify the characteristics of the motor for optimum motor
control. After the motor ID run, the drive is stopped. Note: This parameter cannot be changed while
the drive is running.
Once the motor ID run is activated, it can be cancelled by stopping the drive: If motor ID run has
already been performed once, parameter is automatically set to
performed yet, parameter is automatically set to
performed.
Notes:
• Motor ID run can only be performed in local control (ie, when drive is controlled via PC tool or
control panel).
• Motor ID run cannot be performed if parameter
• Motor ID run must be performed every time any of the motor parameters (99.04, 99.06...99.12)
have been changed. Parameter is automatically set to STANDSTILL after the motor parameters
have been set.
• With permanent magnet motor, the motor shaft must NOT be locked and the load torque must be <
10% during the motor ID run (Normal/Reduced/Standstill).
• Mechanical brake (if present) is not opened during the motor ID run.
• Ensure that possible Safe Torque Off and emergency stop circuits are closed during motor ID run.

99.05 MOTOR CTRL MODE
No motor ID run is requested. This mode can be selected only if the
motor ID run (Normal/Reduced/Standstill) has already been performed
once.
Guarantees the best possible control accuracy. The motor ID run
takes about 90 seconds. This mode should be selected whenever it is
possible.
Note: The driven machinery must be de-coupled from the motor with
Normal ID run:
• if the load torque is higher than 20%.
• if the machinery is not able to withstand the nominal torque transient
during the motor ID run.
Note: Check the direction of rotation of the motor before starting the
motor ID run. During the run, the motor will rotate in the forward
direction.
WARNING! The motor will run at up to approximately
50...100% of the nominal speed during the motor ID run.
ENSURE THAT IT IS SAFE TO RUN THE MOTOR BEFORE
PERFORMING THE MOTOR ID RUN!
