Details of Parameters
PrNo. Parameter Value Function
For linear motion or other similar motion, overtraveling of the work may cause mechanical
damages. To avoid this, it is necessary to provide a limit switches at each end so that traveling
over the limit switch position can be inhibited.
<Notes>
1. With Pr04 = 0 and CCW/CW off (not connected to COM-), the
driver will trip with "overtravel limit input error" assuming that
traveling over the limit occurs simultaneously in both the CCW
and CW directions.
2.
You can specify whether or not to use the dynamic brake
during deceleration after CCW or CW overtravel limit
input (CCWL or CWL) becomes active. For details, see
the description of Pr66 (DB inhibition at overtravel limit).
