Parameters 497
99.12 Motor nominal
torque Defines the nominal motor shaft torque. This value can be
given instead of nominal power (
99.10 ) if shown on the rating
plate of the motor.
The unit is selected by parameter
96.16 Unit selection .
Notes:
• This setting is an alternative to the nominal power value
( 99.10 ). If both are entered, 99.12 takes priority.
• This parameter cannot be changed while the drive is
running.

99.13 ID run requested Selects the type of the motor identification routine (ID run)
performed at the next start of the drive. During the ID run, the
drive will identify the characteristics of the motor for optimum
motor control.
If no ID run has been performed yet (or if default parameter
values have been restored using parameter
96.06 Parameter
restore ), this parameter is automatically set to Standstill ,
signifying that an ID run must be performed.
After the ID run, the drive stops and this parameter is
automatically set to
None .
Notes:
• For the Advanced ID run, the machinery must always be
de-coupled from the motor.
• With a permanent magnet or synchronous reluctance
motor, a Normal , Reduced or Standstill ID run requires that
the motor shaft is NOT locked and the load torque is less
than 10%.
• With scalar control mode ( 99.04 Motor control mode =
SMC ), only the Current measurement calibration ID run
mode is possible.Configure motor temperature
measurement (if used) in parameter group
35 Motor
thermal protection before activating the ID run.
• If a sine filter is installed, set the appropriate bit in
parameter 95.15 Special HW settings before activating the
ID run. With a non-ABB (custom) filter, set also 99.18 and
99.19 .
• With scalar control mode ( 99.04 Motor control mode =
SMC ), the ID run is not requested automatically. However,
an ID run can be performed for more accurate torque
estimation.
• Once the ID run is activated, it can be canceled by
stopping the drive.
• The ID run must be performed every time any of the motor
parameters ( 99.04 , 99.06 … 99.12 ) have been changed.
• Ensure that the Safe torque off and emergency stop
circuits (if any) are closed during the ID run.
• Mechanical brake (if present) is not opened by the logic for
the ID run.
• This parameter cannot be changed while the drive is
running.
None ;
Standstill
( 95.21 b1/b2)
None No motor ID run is requested. This mode can be selected
only if the ID run
( Normal , Reduced , Standstill , Advanced ,
Advanced Standstill ) has already been performed once.
