Yaskawa SGDS Sigma III Servo Amplifier - Manual (Page 225)

7 Operation
7.7.3 Multi-turn Limit Setting
7-36
Change the setting using the following procedure.
1. Change the multi-turn limit setting (Pn205), and then turn OFF the SERVOPACK control power and turn
it ON again. The alarm A.CC0 occurs. The multi-turn limit value for the encoder is setting 65535, the
same as for the SERVOPACK’s factory setting. Therefore, if only the multi-turn limit value for the SER-
VOPACK is changed, the alarm occurs.
Alarm Name: Multi-turn Limit Disagreement
2. The multi-turn limit value for the encoder must be set to the same value as that for the SERVOPACK.
Change the multi-turn limit value for the encoder using the following procedure.
Use a digital operator for the following operation. This operation is enabled only while the alarm A.CC0
occurs.
• Refer to 11.3.3 Multi-turn Limit Setting for details about how to use the adjusting command
(ADJ: 3EH).
The multi-turn limit setting in the encoder can be changed only while the Multi-turn Limit Disagreement (A.CC0) has
occurred. The setting is enabled by turning OFF the control power and turning it ON again.
