User manual of EL8-EC***F AC Servo
53
When it is an open collector output, max current: 50mA, max supplying voltage: 25V.
Please ensure the switching power supply fulfills the conditions.
If the load is an inductive load such as a relay, please connect a flyback diode in
parallel in reverse. A wrong installation of the flyback diode might cause damage to
the driver.
Pin 12, 40 and 41 are 2 single ended outputs; pin 11+10 and 35+34, pin 37+36 and
39+38 are 2 double ended outputs.
2.16.4 Probe input
EL8-EC series servo drives use DI5 and DI6 as probe input terminals. DI5/DI6 is default
as probe function if no other function is assigned to them. Internal circuit is a bidirectional
optocoupler.
