7.2.2 DI Function Explanation
Input terminals( 8 input terminals are corresponding to the definitions of
P3-0,P3-1,P3-2,P3-7).

Explanation
0
NULL
No
Input state dose not effect system.
1
SON
Servo Enable
Input terminal of servo enable.
OFF: servo driver can not be enabled and serv omotor
is not excited.
ON:servo driver is enabled and servomotor is excited.
2
ARST
Alarm Clear
Input terminal of alarm clearance.
When an alarm occurs and if the alarm is allowed
clearance, the rising edge( from OFF becomes ON) of
ARST will clear the alarm. Attention: only a part of
alarms are allowed to clear.
3
CCWL
CCW Drive
Inhibition
1.Input terminal of CCW drive inhibition:
OFF
:
Inhibit CCW running.
ON
:
Enable CCW running.
2.Use this function for protection of the mechanical
traveling limit.The function is controlled by the
parameter PA20. Pay attention to that the default value
of PA20 neglects this function.Therefore needs to
modify PA20 if need to use this function:
(1)
:
When PA20=0
,
the function of input inhibition is
effective. Whether to inhibit is decided by PA83.
(2)
:
When PA20=1, the function of input inhibition is not
effective. Whether to inhibit is not decided by PA83
3. Inhibition function is valid(PA20=0):
(1) PA83=0, CCW torque limit is 0,but it does not
limit CCW pulse input.
(2)
PA83=1, it does not inhibit CCW pulse input.
4
CWL
CW Drive
Inhibition
1.The input terminal of CW drive inhibition
OFF
:
Inhibit CCW running.
ON
:
Enable CW running.
