Absolute Position Detection
7.2.4 Multi-turn Limit Setting
7-12
Alarm Name: Multi-turn Limit Disagreement
Note: OFF: Output transistor is OFF (alarm state).
ON: Output transistor is ON.
When this alarm occurs, the multi-turn limit in the encoder must be changed. The auxiliary
function mode of the Digital Operator is used to change this setting. It can also be set from a
personal computer using the Monitor Software.
The procedure to set the multi-turn limit in the encoder using the Digital Operation is pro-
vided next.
The multi-turn limit setting in the encoder can be changed only when the Multi-turn Limit Disagree-
ment alarm has occurred. After changing the setting, turn the power supply OFF and then back ON.
„ Changing the Setting with the Hand-held Digital Operator
1. Press the DSPL/SET Key to select the auxiliary function mode.
2. Select the parameter Fn013. Press the Left or Right Cursor Key to select the digit to set,
and then press the Up or Down Cursor Key to change the number.
3. Press the DATA/ENTER Key. The following display will appear.
4. Press the DSPL/SET Key. The following display will appear and the multi-turn limit
setting in the absolute encoder will be changed.
5. Press the DATA/ENTER Key to return to the auxiliary function mode.
This completes the procedure to change the multi-turn limit setting in the absolute encoder.
Turn the power supply OFF and then back ON.
