9.6 Warning Output
9.6.1 Overtravel Warning
For position control and velocity control types (including control mode switching type at the time of position
control or velocity control), this function controls motor revolution in accordance with the external signal
status.
Motor operation is controlled separately for forward revolution and backward revolution by overtravel signal.
1. Setting and connection
1) Set Func0-bit5,4,3 of Mode2-Page1 for overtravel warning
Bit5 : Select polarity of overtravel signal
Bit4 : Forcible setting of forward revolution overtravel signal
Bit3 : Forcible setting of backward revolution overtravel signal
In case of forcible setting (bit4, 3 = “1”) at bit 4, 3, the signal always becomes ON regardless of the
CN1-32, 33 pins input status. By combining with bit5, polarity select, the status of “forward/backward
revolution overtravel ineffective” or “always forward/backward revolution overtravel” is possible.
2) Connect the forward overtravel signal to CN1-32 pin and the backward overtravel signal to CN1-33 pin.
2. Operation when overtravel warning is issued
- Refer to chapter 6, Overtravel Sequence, for the motor operation.
- Displays for 7-segment LED are for forward revolution overtravel, and for backward revolution
overtravel. No alarm is output.
3. Precautions
1) Overtravel warning is only effective during SON status. Even if the overtravel signal is input while in
SOFF, the status or display will not change.
2) Operation of command ineffective (forced zero) differs between the position and velocity control types.
- For the position control type, command pulses are inhibited at the revolution side where overtravel
signal is input.
- For the velocity control type, the velocity command becomes zero (VCMD = 0) at the revolution side
where overtravel signal is input. These settings are validated when the acceleration/deceleration time
(Tvac, Tvde) or low pas filter parameter (VLPF) is set.
3) For the torque control type (including control mode switching type at the time of torque control),
overtravel is ineffective, therefore overtravel signal input does not control the motor operation.
4) At test mode JOG operation, overtravel input is validated. Operation at the revolution side where
overtravel signal is input is controlled.
5) When the signal input is canceled, overtravel warning will automatically recover.
