Annotations
Command "Calculate motor
control parameters" (C4600)
Requirements
DOK-INDRV*-FU*********-IB01-EN-P
• motor control parameters for field-oriented current control (FOC) of
asynchronous motors
• motor control parameters for voltage-controlled operation (U/f) of
asynchronous motors without encoder
As regards the operating principle of the command C3600, observe the
following points:
• Motor motion is not required; the motor holding brake possibly applied
at "Ab" remains applied. The motor does not generate torque. With
little friction and inertial mass, little motion can however occur!
• When the command was processed without error, the calculated
values of motor and motor control parameters are operational. If the
command execution is aborted during the measurement, all motor and
motor control parameters remain unchanged.
Calculating the Motor Control Parameters from the Motor
Parameters
For synchronous motors and in special cases (see "Requirements" below)
for asynchronous motors it is possible via C4600 Command Calculate
motor control parameters to calculate the motor control parameters
from the motor parameters.
Note: The command C4600 can only be activated in the parameter
mode (communication phase "P2" or "P3")!
The figure below illustrates the scope of functions of the command
C4600:

Fig. 7-61: Function of C4600 Command Calculate motor control parameters
To execute the command C4600 the following requirements have to be
fulfilled:
• Synchronous third-party motors require manual input of the motor
data in the motor parameters (see "Third-Party Motors at IndraDrive
Controllers" in chapter "Motor, Mechanical Axis System, Measuring
Systems").
• For asynchronous third-party motors the command C4600 is only
useful if the motor control parameters are to be generated from
specific, manually input motor parameters (e.g. from equivalent circuit
diagram data, see "Third-Party Motors at IndraDrive Controllers" in
chapter "Motor, Mechanical Axis System, Measuring Systems"). The
