Command Descriptions
83
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.)
The
DMTICD
command sets the percentage current derating at rated speed (
DMTW
). This value sets the extent
to which continuous current must be reduced at speed to compensate velocity-related losses in the motor.
For example,
DMTICD3
sets the motor’s continuous current derating to 3% (or 97% of continuous value
DMTIC
) at the motor’s rated speed (
DMTW
). At half this speed, it will be reduced 1.5%.
DMTIND
Motor Inductance
Type
Motor
Syntax
<a_><!>DMTIND<r>
(does not take effect until RESET, DRESET or
cycle power)
Units
r = mH
Range
0.0 to 200.0 : ±0.1
Default
0.0 (DMTIND of 0 results in motor config. error)
Response
DMTIND
*DMTIND10

DMTLMN, DMTLMX, DMTR, TASX, TCS
Product Rev
GT6K 6.0
GV6K n/a
(applicable only to
stepper 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.) 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
-32726 to the
TCS
register, and shuts down the drive (
DRIVE0
).
The
DMTIND
command sets the motor phase inductance for stepper motors only (servo motor inductance is
set with
DMTLMN
and
DMTLMX
). The motor inductance entered is the motor phase inductance you measure
across one phase at the motor terminals of the drive. The inductance value is the “small signal inductance”
as measured by a hand-held or bench-top inductance meter at 1 KHz.
A procedure for configuring motor inductance (for non-Parker motors) is provided in the
Configuration
chapter of the
Hardware Installation Guide
.
DMTIP
Peak Current
Type
Motor
Syntax
<a_><!>DMTIP<r>
Units
r = Amps-RMS
Range
0.00 to 128.00 : ±0.01
Default
0.00 (DMTIP of 0 results in motor config. warning)
Response
DMTIP: *DMTIP7.50

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 warning with
TASX
bit 28, and a value of
51 is written to the
TCS
configuration status register.
The
DMTIP
command sets a limit that the commanded current cannot exceed. This is typically set to three
times the motor’s continuous current rating (
DMTIC
) or less.
