NOTE: This command does not take effect until you cycle power to the drive, or issue a
command.
AUTO-SETUP:
This command is automatically set according to the Parker motor selected with the
configuration utility in Motion Planner (see page 6). If you did not use the configuration utility or are not using a
Parker Motor, this command is set to zero and you will have to manually set this parameter. (Refer to DMTR
for a list of auto-configured commands.) If the drive is powered up when this command is set to zero (for
instance, if RFS is executed), the drive reports a motor configuration error with TASX bit 7, writes a value of
-32725 to the TCS register, and shuts down the drive (DRIVE0).
command sets the motor winding resistance. This resistance value is measured at 25 °C at the
The
DMTRES
drive end of the motor cable (motor cable included). For steppers, this resistance is a phase resistance
measured at terminals A+ to A-, or B+ to B-. For servos, this resistance is the phase-to-phase resistance
measured at termnals U to V, V to W, or W to U.
NOTE: Disconnect the motor cable from the drive before attempting to make this measurement. For best
accuracy, and to avoid injury, this measurement must be made with the motor cable disconnected from the
drive.
