ZEROSPD input being ignored, it is determined that it is not speed
zero clamp state at all times.
ZEROSPD input has been enabled. If connection with COM- is
opened, speed command will be regarded as zero.
04 0 – 1 Overtravel input
inhibit
In the case of linear driving, in particular, to prevent mechanical damage due to
overtraveling of work, you should provide limit switches on both ends of the axis, as
shown below, whereby driving in a direction of switch action is required to be
inhibited.
<Cautions>
1. When you set 0 to Pr04 and do not connect both CCWL and CWL inputs to COM-
(off), abnormal condition in which limits are exceeded in both CCW and CW
directions is detected, and the driver will then trip due to “abnormal overtravel
input inhibit“.
2. You can set whether or not to activate the dynamic brake when slowdown occurs
because CCW or CW overtravel input inhibit has been enabled. For details, refer
to descriptions on Pr66 (DB deactivation at overtravel input inhibit).
