DMTRES
Motor Winding Resistance
Type
Motor
Syntax
<a_><!>DMTRES<r>
(does not take effect until RESET, DRESET or
cycle power)
Units
r = Ohm (measured line-to-line)
Range
0.00 to 50.00 : ±0.01
Default
0.00 (DMTRES of 0 results in motor config. error)
Response
DMTRES: *DMTRES7.50

NOTE : This command does not take effect until you cycle power to the drive, or issue a
RESET
or
DRESET
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
).
The
DMTRES
command sets the motor winding resistance. This resistance value is measured at 25
°
C at the
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.
DMTRWC
Motor Winding Thermal Resistance
Type
Motor
Syntax
<a_><!>DMTRWC<r>
(does not take effect until RESET, DRESET or
cycle power)
Units
r = Degrees Celsius/Watt (
°
C/W)
Range
0.00 to 50.00 : ±0.01
Default
0.00
Response
DMTRWC: *DMTRWC23.60

GV6K 6.0
(applicable only to
servo axes)
NOTE : This command does not take effect until you cycle power to the drive, or issue a
RESET
or
DRESET
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.)
DMTRWC
specifies the temperature rise of the motor winding above motor case temperature per watt of
winding power dissipation. Motor heatsinking does not affect this value. See the
DMTMAX
command for
more information on how the drive estimates motor temperature.
