Output
1. In-Position
In-position output is motor drive complete signal and it is output when drive is complete by command pulses.
- When motor is arrived at the command position, in-position output is [H]. (position error=0)
- When drive is complete and motor rotates by the external force,
-1.8°≤ Position error ≤ 1.8° : In-position = [H]
Position error < -1.8°, Position error > 1.8° : In-position = [L]
The in-position LED turns ON/OFF depending on in-position output [H]/[L].
For accurate drive, check the in-position output again and execute the next drive.
※ Refer to example of output circuit connection.
2. ALARM OUTPUT
When alarm occurs, driver recognizes the alarm. The alarm LED (red) and alarm output represents the errors.
● Alarm output signal
-In case of normal status, output is [H]. When alarm occurs, output is [L].
-When supplying alarm reset, output turns [H].
※ Refer to example of output circuit connection.
● Alarm indicator
Depending on the number of flashing of alarm indicator, you can check alarm causes.
No. of flashing Alarm type
1
Over current error
2
Over speed error
3
Position tracking error
4
Over load error
5
Over heat error
6
Motor connection error
7
Encoder connection error When encoder cable connection error occurs at driver
※ Depending on alarm type, it flashes the number of flashing with 400ms
interval. The waited 800ms signals output repeatedly. Until clearing
alarm by alarm reset signal, alarm signal output continuously.
3. Example of output circuit connection
-It is recommended to use below 50VDC at VCC. Use the R
driver to be within 25mA following the below formula.
