 For Source type open collector (External power only)
* It will be cause of wrong operation by pulse missing or circuit failure when input current to servo
amplifier is less than 3.8mA or more than 15mA.
* It will be cause of wrong operation by pulse missing or circuit failure when collector-emitter
voltage (V
CE
) of a transistor in host unit is more than 1.5V.
