10 Quick Start-up Guide for ACS850 with Standard Control Program
• maximum torque
For the Normal ID run (see below), this value should
be at least 100% of motor nominal torque defined
earlier.
20.07 Maximum torque1
• minimum torque 20.08 Minimum torque1
The question “Do you want to perform id-run now?” is displayed. The ID run
(identification run) will identify the characteristics of the motor for optimum control.
If you do not wish to perform the ID run at this point, select No to complete the Motor
Set-up firmware assistant. Proceed to section 3 – Start/Stop configuration.
If you wish to perform the ID run, continue with the following steps BEFORE selecting
Yes.
WARNING! With Normal or Reduced ID run 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!
Check the direction of rotation of the motor. During
the run (Normal or Reduced), the motor will rotate in
the forward direction.
Ensure the Safe Torque Off and emergency stop
circuits (if present) are closed.
Select Yes and press OK.
Select the ID run method.
The ID run will be performed at the next start of the
drive.
99.13 Idrun mode
NORMAL ID run should be selected whenever
possible.
Note: 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.
The REDUCED ID run should be selected instead of
the Normal ID run if the mechanical losses are
higher than 20%, i.e. the motor cannot be
de-coupled from the driven equipment, or full flux is
required to keep the motor brake open (conical
motor).

V2 and W2 are connected to the
corresponding motor terminals:
