When the setup value is 0, CCWTL and CWTL will be limited by Pr5E (1st torque
limit setup). At the torque control, Pr5E becomes the limiting value for CCW/CW
direction regardless of the setup of this parameter.
In linear drive application, you can use this over-travel inhibiting function to inhibit the

motor to run to the direction specified by limit switches which are installed at both ends

of the axis, so that you can prevent the work load from damaging the machine due to
the over-travel. With this input, you can set up the action of over-travel inhibit input.

<Cautions>
1. When Pr04 is set to 0 and over-travel inhibit input is entered, the motor deceler-
ates and stops according to the preset sequence with Pr66 (Sequence at over-
travel inhibition). For details, refer to the explanation of Pr66.
2. When both of CCWL and CWL inputs are opened while Pr04 is set to 0, the driver
trips with Err38 (Overtravel inhibit input error) judging that this is an error.
3. When you turn off the limit switch on upper side of the work at vertical axis applica-
tion, the work may repeat up/down movement because of the loosing of upward
torque. In this case, set up Pr66 to 2, or limit with the host controller instead of us-
ing this function.
0 to 9 You can set up the content of analog speed monitor signal output (SP : CN X5,
<3> Pin43) and the relation between the output voltage level and the speed.
