Explanation of the parameters
Parameterization of MOVIPRO
®
P93x IPOS special functions
P930 Override
Setting range: On/off
The override function makes it possible to change the travel speed for positioning oper-
ations which is programmed in the IPOS
plus®
program. The speed can be altered within
the range from 0 to 150 % of the specifically programmed speed. This requires an ana-
log input, with 0 to 150 % corresponding to 0 – 10 V at the analog input. The maximum
speed value is limited by
P302/P312 Maximum speed 1/2
(page 99).
P933 Jerk time
Setting range: 0.005 – 2 s
The jerk time indicates the duration of the torque formation. The positioning time in com-
parison to the linear ramp is extended by the set jerk time. Make sure that
P911/P912
Positioning ramp 1/2
(page 124) is of a greater or equal value:
P933
≤
P911
P933
≤
P912
If this is not true, torque formation still has a trapezoidal shape with the set jerk time not
being the time for the torque formation.
P938 IPOS speed
task 1
Setting range: 0 – 9 additional assembler commands/ms
The standard setting for task 1 is "1". The speed can be increased by up to 9 additional
assembler commands per millisecond with P938. P938 and
P939 IPOS speed task 2
(page 128) share the resources for the speed increase; that is, task 1 and task 2 to-
gether can be assigned a total of 9 additional assembler commands per millisecond. Ex-
ample:
Task 1 + 2 additional assembler commands/ms = 3 assembler commands/ms
Task 2 + 7 additional assembler commands/ms = 9 assembler commands/ms
P938 IPOS speed
task 2
Setting range: 0 – 9 additional assembler commands/ms
The standard setting for task 2 is "2". The speed can be increased by up to 9 additional
assembler commands per millisecond with P939. P939 and
P938 IPOS speed task 1
(page 128) share the resources for the speed increase; that is, task 1 and task 2 to-
gether can be assigned a total of 9 additional assembler commands per millisecond. Ex-
ample:
Task 1 + 2 additional assembler commands/ms = 3 assembler commands/ms
Task 2 + 7 additional assembler commands/ms = 9 assembler commands/ms
