Parameter Descriptions
● BACK EMF
Set the motor's Back EMF phase to phase, rms value (Ke, Volts rms per 1000 rpm)
On a standard PMAC motor the following equation may be used to check that the BACK EMF value is approximately correct:
BACK EMF * MAX SPEED < AC Input voltage
● R
Set the motor's resistance, between phases at 25 °C. This parameter is used within the current loop.
● L
Set the motor's inductance at maximum current. This parameter is used within the current loop and is related to the overall
proportional gain.
PHASE
Set the motor's phase shift advance at permanent current. If this parameter is unknown, value must be set to 0.
The current setpoint I is separated into two current setpoints Iq and Id, obeying the following rule :
