APPENDIX
Notes:
1.
Pin 1 must be shield drain wire connected to peripheral device
frame ground.
2.
It is not possible to drive two drives simultaneously.
3.
The peripheral drive duty must satisfy the following:
ON time / (ON time + OFF time)
≤
0.2
4.
The resistance of the peripheral drive solenoid must be 24
Ω
or
higher.
If it is lower than 24
Ω
, over-current may flow into the solenoid,
causing the solenoid to burn.
