DATA, SRV, SPIN, PARA, LAD, MULT, IPWD, LINK, MCT, EXIN, CVIN, SUIN, ENC, PLC, APLC, STOP, STP2
Refer to Emergency stop cause (G10221/R21) to confirm which causes are detected.
EMG Emergency stop PLC
Details
The built-in PLC has entered the emergency stop state during the sequence process.
Remedy
- Investigate and remove the cause of the built-in PLC emergency stop.
EMG Emergency stop EXIN
Details
The "emergency stop" signal is significant (open).
Remedy
- Cancel the "emergency stop" signal.
- Check for any broken wires.
EMG Emergency stop SRV
Details
An alarm occurred in the servo system causing an emergency stop.
Remedy
- Investigate and remove the cause of the servo alarm.
EMG Emergency stop STOP
Details
The sequence program in PLC is not running.
Remedy
- Check the setting of the toggle switch in front side of the PLC module. Correct it if set to STOP.
EMG Emergency stop SPIN
Details
Spindle drive unit is not mounted.
Remedy
- Cancel the causes of the other emergency stop.
- Check the "emergency stop" signal input in the spindle drive unit.
EMG Emergency stop PARA
Details
Setting of the door open II fixed device is illegal.
Setting of the parameters for dog signal random assignment is illegal.
Remedy
- Correct the "#1155 DOOR_m" and "#1156 DOOR_s" settings. (When the door open II fixed device is
not used, set "#1155 DOOR_m" and "#1156 DOOR_s" to "100".)
- Correct the "#2073 zrn_dog (Origin dog Random assignment device)", "#2074 H/W_OT+ (H/W OT+
Random assignment device)", "#2075 H/W_OT- (H/W OT- Random assignment device)" and "#1226
aux10/bit5 (Arbitrary allocation of dog signal)" settings.
