Servo On SON ALL
SON and IG24 close loop: Servo ON ; SON and IG24 open loop:
Servo OFF. Attention: Before power on, the input connect point
SON (servo on) can not be operated to avoid danger.

Abnormal Reset ALRS ALL
ALRS and IG24 close loop: Relieving the stop-situation from of
abnormality. But the abnormality of encoder or memory will
cause the same alarm again. Please reset power after the
abnormality is eliminated.
8-1
PI/P switch PCNT Pi/Pe/S
PCNT and IG24 close loop will cause the speed loop control
transforming to ratio control from ratio integration control.

CCW
Operation limit
CCWL ALL
Connect to CCW over travel detector: CCW L and IG24 close loop;
open loop with IG24 -> CCW over travel operates.

CW
Operation limit
CWL ALL
Connect to CW over travel detector: CWL and IG24 close loop;
open loop with IG24 -> CW over travel operates. 5-4-8

External torque
limit
TLMT Pi/Pe/S
TLMT and IG24 close loop will cause the motor-output-torque-limit
to stay in the command-voltage range of
torque-limit-terminal-layout (
PIC
、
NIC ).

Pulse error
amount delete
CLR Pi/Pe
When CLR and IG24 close loop, delete the pulse amount in the
Position Error Counter.
5-4-7
Servo lock LOK S
When LOK and IG24 close loop will transform speed control mode
into position control mode in order to lock the motor at the last
position. 5-3-12
Emergency stop EMC ALL
When EMC and IG24 close loop: Emergency stop -> Servo Off and
exit the rotating statue, and Cn008 will decide if the dynamic Brake
operates. 5-6-4
