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 ID run, the drive is stopped. Note: This parameter cannot be changed while the drive
is running.
Once the ID run is activated, it can be cancelled by stopping the drive: If ID run has already been
performed once, parameter is automatically set to
parameter is automatically set to
Notes:
• ID run can only be performed in local control (i.e. when drive is controlled via PC tool or control
panel).
• ID run cannot be performed if parameter
• 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 ID run (Normal/Reduced/Standstill).
• Mechanical brake (if present) is not opened during the ID run.
• Ensure that possible Safe Torque Off and emergency stop circuits are closed during ID run.

(0) NO. If no ID run has been performed yet,
(3) STANDSTILL. In this case, the ID run must be performed.
99.05 MOTOR CTRL MODE
No motor ID run is requested. This mode can be selected only if the ID
run (Normal/Reduced/Standstill) has already been performed once.
Guarantees the best possible control accuracy. The 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 ID run.
Note: Check the direction of rotation of the motor before starting the
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 ID run. ENSURE
THAT IT IS SAFE TO RUN THE MOTOR BEFORE
PERFORMING THE ID RUN!
Reduced ID Run. This mode should be selected instead of the Normal
ID Run
• if mechanical losses are higher than 20% (i.e. the motor cannot be
de-coupled from the driven equipment), or
• if flux reduction is not allowed while the motor is running (i.e. in case
of a motor with an integrated brake supplied from the motor
terminals).
With Reduced ID run, the control in the field weakening area or at high
torques is not necessarily as accurate as with the Normal ID run.
Reduced ID run is completed faster than the Normal ID Run (< 90
seconds).
Note: Check the direction of rotation of the motor before starting the
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 ID run. ENSURE
THAT IT IS SAFE TO RUN THE MOTOR BEFORE
PERFORMING THE ID RUN!
