The interface with the input circuit
Use relay or open collector transistor circuit to connect. Please choose micro-current relay when using
relay. Otherwise, the contact will be not good.
Open collector output (24V power supply) Relay output (24V power supply)
Host device servo drive
Host device servo drive
Notes: the max allowable voltage and current of open collector output:
Voltage: DC30V (max)
Current: DC50mA (max)
The interface with the output circuit
The signal output circuit of servo unit is open collector signal. Please build the input circuit at the host
side according to the output circuit condition.
