5.1 Stop Operation
5-3
 Execution of stop operations
Stop controls are executed when the following I/O signals turn on.
 Allocation of I/O signals (Output)
Signal name
I/O number
Axis 1
Axis 2
Axis 3
Axis 4
CH0 CH1 CH2 CH3
System stop
Y800
Emergency stop
Y830 Y831 Y832 Y833
Over limit input (+) (Note 2) (Y860) (Y862) (Y864) (Y866)
Over limit input (-) (Note 2) (Y861) (Y863) (Y865) (Y867)
Deceleration stop
Y838 Y839 Y83A Y83B
(Note 1): The over limit input (+) and over limit input (-) will be valid when arbitrary inputs are allocated and the output
relays indicated in the above table turn ON.
5.1.2 Characteristics of Stop Operations
 Priority of stop operations
When stop control requests are made simultaneously, the stop operations are executed
according to the following priority.
1. System stop > 2. Emergency stop > 3. Limit stop > 4. Deceleration stop
 Dwell time setting
The dwell time setting is invalid in the stop operations regardless of patterns.
 Flag processing
• In the case of system stop, the busy signal turns off and the operation done signal turns on.
• In the cases of emergency stop, limit stop and deceleration stop, the busy signal turns off
and the operation done signal turns on after the completion of the pulse output during
deceleration.
 Elapsed value area (Current value coordinate)
• Even in a stop operation, the elapsed value area is always updated.
• After the emergency stop, limit stop or deceleration stop, deceleration is performed with
each specified deceleration time, and the value when the pulse output stops is stored.
• In the case of system stop, the value when the pulse output stops is stored.
KEY POINTS
• For details of the deceleration stop operations when repetitive control is
executed, refer to “5.5.3 Stop Operation During Repeat Operation”.
