7.5 Trigger Pulse Output
This function is used when the output signal becomes ON periodically in specific condition. This
function can be used in absolute coordinate system.
* Ezi-SERVO ALL-28 is not support this function
.
1) Setting
This function is working with RS-485 communication (DLL library) method only. This command can
be executed during the positioning command or before the positioning command also. The following
table shows the setting conditions and refer to
「
User Manual
– Communication Function
」
.
Setting Item Description Range
Start/Stop Setting start/stop of pulse output.
0~1
Pulse Start
Position
Setting the start position of first pulse output.
-134,217,727 ~
134,217,727
Pulse Period
Setting the pulse period.
( 0 : pulse output only 1 time in Pulse start position.
1~ : pulse output repeatedly depends on setting.)
0~134,217,727
Pulse Width Setting the pulse width.
1~1000[ms]
2) Formular for Setting Items
To calculate the minimum
‘Pulse Period’ value, the next formular is used.
The minimum
‘Pulse Period[pulse]’ = (speed / 1000) * pulse_width * 10
(where - Motioning speed = speed[pps]
- Pulse width = pulse_width[msec] )
For example, the motioning speed is 100,000[pps], pulse width is 5[msec] ,
The minimum ‘pulse
period’ must set to more than ‘5000[pulse] value.
Attention
 The pulse is output only in bigger position area than ‘pulse start
position’ and is output in incremental motion direction
.
Attention

The sign of
current position value and the sign of ‘pulse start position’
must be same to pulse output .
