Positioning controller
ACCEL (acceleration in NC mode)
Command Parameters Unit Group
ACCEL_1 X
ACCEL_2 X x= 1… 20000 mm/s
POS_1 / NC
POS_2 / NC
This command is used to define the acceleration in NC mode.
The command is only active if the VMODE has been parameterized to NC. For stable operation, it
must be set to a little less value than technically possible acceleration. Normally the the multiple
of 3…5 shoul d be considered.
VMAX (maximum speed in NC mode)
Command Parameters Unit Group
VMAX_1 X
VMAX_2 X
x= 1… 5000 mm/s
POS_1 / NC
POS_2 / NC
Specification of the maximum speed in NC mode.
This value is defined by the drive system and should be specified as precisely as possible (not too
high under any circumstances). The speed is scaled by the external speed demand set via Profibus.
The command is active if the VMODE has been parametrized to NC only.
If the speed differs between the two directions of movement the lower value should be entered.

(loop gain setting)
Command Parameters Unit Group
V0_1:I X
V0_2:I X
i = A|B|RES
x = 1… 200
RES: x = 1|100
s -1
POS_1 / NC
POS_2 / NC
This parameter is specified in s
-1
(1/s).
This parameters work only in NC mode, replacing the use of deceleration stroke parameters.
Usually in NC Mode the loop gain is specified rather than the deceleration distance.
The internal gain is calculated from this gain value together with the parameters VMAX and
SYS_RANGE.
