DIGN
Current Loop Gain
Type
Tuning
Syntax
<a_><!>DIGNc<r>
Units
c = gain identifier letter (required);
r = gain value
Range
c = A, B, C, or D;
DIGNA, DIGNB, DIGNC : r = 0.000 to 15.000 : ±0.001
DIGND : r = 0.000 to 1.000 : ±0.001
Default
r = 0.000 (DIGNc of 0 results in motor config. warning)

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 writes a value to the
TCS
register (46 for
DIGNA
, 47 for
DIGNB
, 48 for
DIGNC
, or 49 for
DIGND
).
Use the
DIGN
command to set values for the gain terms in the stepper current loop, which optimizes drive
performance for a specific motor.
Setting
DIGN
values for Non-Parker Motors:
NOTES
•
The drive must be disabled (
DRIVE0
) before making any changes to the
DIGN
values.
•
When making changes to
DIGNA
,
DIGNB
and
DIGNC
values, the ratio between the
values must remain constant. That is, multiply or divide all three gain values by the same
amount.
•
Increasing the
DIGN
values can improve system performance; however, setting an
excessive
DIGN
value will cause the motor to “sing” (emit a high-pitched squeal or
screech) when it is at rest and to heat unnecessarily
Calculating initial values * :
DIGNA
=
Inductance (in mH)
2
DIGNB
=
DIGNA
* 0.0896
DIGNC
=
DIGNA
* 0.3578
DIGND
= 0.98 (
this value will not be changed again
)
* If these initial values cause the motor to “sing,” immediately disable the drive (
DRIVE0
)
and lower
DIGNA
,
DIGNB
and
DIGNC
by the same factor; repeat as necessary.
If motor performance is not as high as expected, increase
DIGNA
,
DIGNB
and
DIGNC
by the same factor
(keeping the initial ratio) until system performance is acceptable.
For additional assistance in determining
DIGNc
values for your motor, please consult the factory.

The
DJOG
command allows you to branch into the RP240 front panel jog mode from within your user-
defined program, adjust the position of the axis, and then return to program execution.
