How To Perform The Id Run; Id Run Procedure - ABB ACS355 User Manual

How to perform the ID run

The drive estimates motor characteristics automatically when the drive is started for
the first time and after any motor parameter (group
This is valid when parameter
In most applications there is no need to perform a separate ID run. The ID run should
be selected if:
• vector control mode is used (parameter
2 [VECTOR: TORQ]), and
• operation point is near zero speed and/or
• operation at torque range above the motor nominal torque, over a wide speed
range, and without any measured speed feedback (ie without a pulse encoder) is
needed or
• permanent magnet motor is used and the back emf voltage is unknown.
Note: If motor parameters (group
it must be repeated.

ID run procedure

The general parameter setting procedure is not repeated here. For basic control
panel, see page 75
panels. The ID run cannot be performed without a control panel.
WARNING! The motor will run at up to approximately 50...80% of the
nominal speed during the ID run. The motor will rotate in the forward
direction. Ensure that it is safe to run the motor before performing the ID run!
De-couple the motor from the driven equipment
If parameter values (group
changed before the ID run, check that the new settings meet the following
conditions:
2001 MINIMUM SPEED
2002 MAXIMUM SPEED
2003 MAX CURRENT
2017 MAX TORQUE 1
which limit is in use according to parameter
Check that the Run enable signal is on (parameter 1601).
Ensure that the panel is in local control (LOC shown at the top). Press key
switch between local and remote control.
