11.3.1 Motor parameter identification

If you are using the ASDA-A3 servo drive for motor parameter identification of Z-axis motors, the
identification may fail due to gravity. It is suggested that you place the motor on a flat surface
11
before starting the identification.
After starting ASDA-Soft, check the current control mode of the servo drive. If the servo drive is
in communication mode, first set it to a general mode (i.e. Position, Speed, or Torque mode) and
then cycle the power before executing the Motor Parameter Identification Wizard (see the path
in the following figure). If you do not execute the motor parameter identification, an alarm may
be triggered due to the parameter setting error, or the motor may be burnt due to the motor
current setting error. When you replace the motor with a different motor model, execute the
motor parameter identification again.
During the identification, the motor moves by 1 pole pair distance or 1 pole pitch. It is suggested
that you execute the motor parameter identification before installing the mechanical parts;
otherwise there is a risk of collision when the mechanical parts are moving.
Note: Delta C3 pulse type motors require the motor parameter identification.
