6-3-160 REV_IN
Type:
Axis Parameter
Description:
The REV_IN parameter contains the input number to be used as a reverse
limit input. The number can be set from 0 to 7 and 19. Range 0 to 7 is used to
select one of the MC Unit inputs. Defining value 19 will select the Servo
Driver’s NOT (Reverse drive prohibited, CN1 pin 43) input. As default the
parameter is set to –1, no input is selected.
If an input number is set and the limit is reached, any reverse motion on that
axis will be stopped. Bit 5 of the AXISSTATUS axis parameter will also be set.
Note This input is active low.

STOP command, or by reaching the reverse limit, inhibit, or origin return limit.
