IDrun mode
Selects the type of the motor identification performed at the
next start of the drive (for Direct Torque Control). 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 NO. If no ID run has been
performed yet, parameter is automatically set to
. In
this case, the ID run must be performed.
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
is set to
• ID run must be performed every time any of the motor
parameters (
,
) have been changed.
Parameter is automatically set to
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 (
• Ensure that possible Safe Torque Off and emergency stop
circuits are closed during ID run.
• Mechanical brake is not opened by the logic for the ID run.
No
No motor ID run is requested. This mode can be selected
only if the ID run (Normal/Reduced/Standstill) has already
been performed once.
0
Normal
Normal ID run. Guarantees the best possible control
accuracy. The ID run takes about 90 seconds. This mode
should be selected whenever it is possible.
Notes:
• The driven machinery must be de-coupled from the motor
with Normal ID run, if the load torque is higher than 20%,
or if the machinery is not able to withstand the nominal
torque transient during the ID run.
• 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!
