Wiring of Digital Output
Wiring of the relay circuit
Wiring of the Optocoupler circuit
Note: it is possible to connect a freewheeling diode in the wiring of relay circuit.
(1)
The output circuit is composed of open collector transistor outputs in the Darlington connection, and connect
to relays or photo-couplers.
(2)
The power is provided by the user as the voltage range is DC5 ~ 24V and the current is more than 50mA.
Note: the internal circuit will be damaged if the power polarity is wrongly connected.
(3)
As driving the inductive load such as relay, you must connect a freewheeling diode in parallel.
Note: It would damage the serve drive as if the freewheeling is wrongly connected.
(4)
There exists collector to emitter voltage, VCE (SAT) of approx. 1V at transistor-ON, due to the Darlington
connection of the output or. Note that normal TTL IC cannot be directly connected since it does not meet
VIL.
3.6.3
Wiring of Pulse Input
There are two kinds of pulse inputs, line drive input and open-collector input. The max. input pulse frequency is
500kpps.
BONMET servo drive support three kind of pulse mode (Set by Pn-52):
①
Pulse + Direction;
②
CW+CCW pulse;
③
A/B phase pulse
●
Line drive input
●
Open-collector input
There are two kind of open-collector input: NPN type (like Mitsubishi, Omron, Panasonic) and PNP type (like
Siemens). The wiring of open-collector as below:
Wiring of NPN type pulse input
Wiring of PNP type pulse input
⑴
Check the pulse input kind and make the wiring according to the drawing, otherwise it may cause the damage.
DC 12~24V
