(1) Line Driver I/F
• This signal transmission method is less susceptible to
effects of noise. We recommend this method to improve
reliability of signal transmission.
(2) Open Collector I/F
• The method uses control power supply (V
DC
) external to the
driver.
• This requires a current-limiting resistor (R) that relies on V
DC
.
• Be sure to connect specified resistor (R).
PI
Connection with Sequence Input Signal
• Connect to a contact of switch and relay, or a transistor of an
open collector output.
• When you plan to use a contact input, use switch and relay
for minute electric current so as to avoid poor contact.
• In order to secure appropriate level of primary current of the
photo coupler, set lower limit voltage of the power supply (12
to 24 V) 11.4V or more.

When the connection method is inversed if you use the CW pulse row + CCW pulse row method as
pulse input form, pulses do not count and the motor does not rotate.
Connect so that a photo coupler in the driver on the side on which pulse input is not done turns OFF.
