Digital Input Function
(Except CCWL and CWL are high electric potential, other terminal layout are low electric potential. Please refer
to 5-6-1 to see related parameters)
Signal Name
Function
Sign
Mode I/O Function
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.
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: CCWL 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.
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.
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.
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.
