Interface
⑴
The user provide power supply, DC 12-24V, current
≥
100mA
⑵
Notice:
if current polar connect reversely, servo driver doesn’t run.
3.3.2 Switch Output Interface

Switch
Output
Interface
(1)
The user provide the external power supply . However, if current polarity connects reversely, servo
driver is damaged.
(2)
The output of the form is open-collector, the maximum voltage is 25V, and maximum current is 50mA.
Therefore, the load of switch output signal must match the requirements. If you exceed the requirements or
output directly connected with the power supply, the servo drive is damaged.
(3) If the load is inductive loads relays, etc., there must be anti-parallel freewheeling diode across the load.
If the freewheeling diode is connected reversely, the servo drive is damaged.
