PrNo. Parameter Name Function/Content
In the case of linear driving, in particular, limit switches should be provided on both
ends of the axis, as illustrated in the figure below, to prevent any mechanical dam-
age due to overshoot of a work, and inhibit driving in the direction in which the
switches operate.
1. When you set Pr04 to 0, and do not connect CCWL/CWL input to COM- (OFF), it
will be judged as abnormality in which limits are simultaneously exceeded in both
CCW and CW directions, and the driver will trip due to “Overtravel input error”.
2. You can set whether to activate a dynamic brake during deceleration when CCW
overtravel inhibit input (CCWL) or CW overtravel inhibit input (CWL) works. For
details, refer to descriptions on Pr66 (Deceleration and stop set-up at overtravel
inhibit input).
3. In some cases, after you turn off the limit switch located above a work on the
vertical axis, a work repeatedly moves up and down since there is no longer upward
torque. In this case, don’t use this function, and carry out limit process on the host
controller side.
The parameter is used to select functions of speed zero clamp input (ZEROSPD)/
torque limit switching (TC) input (connector) CN X5 pin 5.
If you wish to use torque limit switching input, also set Pr5E, Pr63, and Pr70 to 73 all
at once. If settings of Pr70 and Pr73 remain 0, the error No.26 acceleration protec-
tion will occur.
This parameter is to allocate functions of warning output(WARN:CN X5 pin 12).
If you ignore output of warning and continue to use, the motor or driver may fail/be
damaged.
