Select the motor identification method by parameter
MODE. During the motor ID run, the drive will identify the
characteristics of the motor for optimum motor control. The motor ID
run is performed at the next start of the drive.
Note: The motor shaft must NOT be locked and the load torque must be < 20% during
Normal ID run. With permanent magnet motor this restriction applies also when
Standstill ID run is selected.
Note: Mechanical brake (if present) is not opened during the motor ID run.
Note: The motor ID run cannot be performed if par.
Scalar.
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
• the machinery is not able to withstand the nominal torque transient during the motor
ID run.
The REDUCED ID run should be selected instead of the Normal ID
run if the mechanical losses are higher than 20%, ie, the motor cannot
be de-coupled from the driven equipment, or full flux is required to
keep the motor brake open (conical motor).
The STANDSTILL ID run should be selected only if the Normal or
Reduced ID run is not possible due to the restrictions caused by the
connected mechanics (eg, with lift or crane applications).
AUTOPHASING can only be selected after the Normal/Reduced/
Standstill ID run has been performed once. Autophasing is used when
an absolute encoder or a resolver (or encoder with commutation
signals) has been added/changed to a permanent magnet motor, but
there is no need to perform the Normal/Reduced/Standstill ID run
again. See parameter
information on autophasing modes, and section
39.
Check the drive limits. The following must apply to all drive ID run
methods:
• 20.05 MAXIMUM CURRENT
In addition, the following must apply for Reduced and Normal ID run:
• 20.01 MAXIMUM SPEED
• 20.02 MINIMUM SPEED
• supply voltage > 66% of
• 20.06 MAXIMUM TORQUE
Normal ID run only)
• 20.06 MAXIMUM TORQUE
Reduced ID run, and permanent magnet motors).
When the motor ID run has been successfully completed, set the limit
values as required by the application.
