Follow-up of Superimposed control

8168 MSO
[Input type] Parameter input
[Data type] Bit path
# 1 MSO When one of the following events occurs in synchronous control, composite control or
superimposed control :
- The emergency stop signal is turned off.
- The servo-off signal is turned on.
- A servo alarm is issued.
0: The synchronous, composite or superimposed control mode is canceled and follow-up
operation is not performed.
For the operation to be performed when the servo-off signal is turned on, however, the
setting of bit 7 (NSR) of parameter No.8161 is used in synchronous control or the
setting of bit 0 (NMR) of parameter No. 8161 is used in composite control.
1: The synchronous, composite or superimposed control mode is not canceled.
The following operation is performed to perform follow-up
operation:
When the emergency stop signal is turned off, the relevant path is determined and
operation is performed so that the emergency stop signal is virtually turned off for the
determined path.
When the servo-off signal is turned on, the relevant axis is determined and operation is
performed so that the servo-off signal is virtually turned on for the determined axis.
When a servo alarm is issued, the relevant axis is determined and the alarm “SV0003
SYNCHRONOUS/COMPOSITE/SUPERIMPOSED CONTROL MODE CAN'T BE
CONTINUED” is issued for the determined axis to stop moving the tool along the axis.
NOTE
1. This setting is valid also during operation. For all axes placed under
synchronous, composite or superimposed control, the emergency
stop signal is turned off, the servo-off signal is turned on, or a servo
alarm is issued.
2. When servo-off is performed during superimposed control, alarm
DS1933 occurs. So, it needs manual reference return.
