Given below are motor parameters for driving a permanent magnet synchronous motor
(PMSM). When driving an induction motor (IM), no setting is required for those parameters.
Refer to Section 9.3 "Notes in Driving PMSM."
P60 Motor 1 (PMSM: Armature resistance)
P61 Motor 1 (PMSM: d-axis inductance)
P62 Motor 1 (PMSM: q-axis inductance)
P63 Motor 1 (PMSM: Induced voltage)
To drive a PMSM, it is necessary to configure a total of seven motor parameters
correctly--the above four motor parameters and three parameters of F04 (Base frequency 1),
F05 (Rated voltage at base frequency 1) and P03 (Motor 1 rated current).
Be sure to consult the motor manufacturer and configure motor parameters correctly.
Incorrect motor parameters may result in a motor or inverter failure.
The factory defaults of P60 through P63 are "0." When any one of P60, P62 and P63 is "0"
(factory default), setting F42 (Control mode selection 1) to "11" (V/f control for PMSM
drive) cannot start the inverter.
P74 Motor 1 (PMSM: Reference current at starting)
P89 Motor 1 (PMSM: Control switching level)
P90 Motor 1 (PMSM: Overcurrent protection level)
P91 Motor 1 (PMSM: d-axis compensation gain under damping control)
P92 Motor 1 (PMSM: q-axis compensation gain under damping control)
P93 Motor 1 (PMSM: Step-out detection current level)
The above six parameters do not require any change basically. Only when any change is
requested by the motor manufacturer, make parameter settings.
