The motor operation could be stabilized if the motor constants are set.
In particular, the motor constants need to be set according to the motor specifications when the auto-
matic boost function, automatic boost function with sensor, sensorless vector control function, 0
Hz-range sensorless vector control function, or vector control function with sensor is used.
The motor constants of standard motor are automatically set to the followings when the motor capacity
or number of motor poles is changed.
Some of the motor constants in the following tables are automatically set to acquired constant data
when the auto-tuning function is used. For details, see the next section.
The motor constants can be chosen from the motor constant selection or manually changed or
adjusted.
The standard motor constants are used as initial values of the induction motor (IM) constants.
Precautions for Correct Use
• Note that the motor constants will be overwritten if any of the following actions are taken.
In case of induction motor (IM):
• The motor capacity or number of motor poles is changed.
• The auto-tuning is performed.
• The initialization is performed.
In case of synchronous motor (SM) and permanent magnet motor (PMM):
• The motor capacity is changed.
• The auto-tuning is performed.
• The initialization is performed.
• Please be advised to save the constants using the R/W function on the LCD operator.
• For details of adjustment, see
7-1 Overview of Motor Control Methods on page 7-3.
