Connector Pin
Symbol
No.
Disconnect EM1-SG to bring the servo motor to a forced stop
CN3 state, in which the servo is switched off and the dynamic
EM1
20 brake is operated.
In the forced stop state, connect EM1-SG to reset that state.
Connector Pin
Symbol
No.
MBR-SG are disconnected when a forced stop is made valid,
an alarm occurs in the interface unit or drive unit, or the
CN3
MBR servo switches off.
