 Open Collector Input
• When an external 24-V power supply is used without current-limiting resistor (at 200 kpps or
lower)
(+24VCW: 1, –CW: 4, +24VCCW: 2, –CCW: 6)
• When an external power supply is used (at 200 kpps or lower)
(+CW: 3, –CW: 4, +CCW: 5, –CCW: 6)
Select an appropriate Current Limit Resistor (R) for Vcc.
