Meaning
Use this parameter to determine the
course of the voltage after the switch-off
point. It is only effective in the relative and
absolute positioning modes.
Directly: The voltage is set directly to 0 V
at switch-off point.
Ramp: As of switch-off point, voltage is
reduced to 0 V using the ramp.
Defines the distance from the destination
at which the drive is slowed down from
creep feed to 0.
If the switch-off difference ≥ the
switchover difference, there is no
switchover point. There is no deceleration
from rapid to creep feed, and instead the
response is executed directly at the
switch-off point.
You can change the switch-off difference
with JOB 3.
Defines the distance from the destination
at which the drive is slowed down from
rapid feed to creep feed.
Time required for a change in voltage via
acc
a ramp from 0 V to10 V.
At 0 ms acceleration is without a ramp.
Time required for a change in voltage via
dec
a ramp from 10 V to 0 V.
At 0 ms deceleration is without a ramp.
