When input 24V Open Collector pulse, please add an external resistor.
(When input pulse, FASTECH step drive is released as 5V Line drive.)

​

1. Input signal and Drive wiring : (Ex) Ezi-SERVO ST

​
2. Consider to add up external resistor

​

Appropriate range of external resistor capacity :
 1) In case of 12V, with Rx=680ohm, available to use 680ohm~1.2kohm
 2) In case of 24V, with Rx=1.8kohm, available to use 1.8kohm~2.2kohm

※ As above, please add individual resistor in case of using more 5V.
    Otherwise inner circuit of drive will be damaged.
