Description
MOTOR.KE defines the back EMF constant for the motor. The back EMF constant defines how much
voltage is generated at the motors coils. The relationship between MOTOR.KE and speed is described by
the following equation:
Coil Voltage = MOTOR.KE * VL.FB
VL.FB is in units of krpm for rotary motors and in units of m/s for linear motors.
The maximum speed for interior permanent magnet motors (IPM) is determined by MOTOR.KE and
VBUS.VALUE. An overspeed fault is generated if MOTOR.TYPE is set to 6 (IPM) and VL.FB *
MOTOR.KE exceeds VBUS.VALUE.
