Note☞
Servo drive internal optocoupler output circuit, maximum allowable voltage and current capacity are as follows：
 voltage：DC30V(max.)
 current：DC50mA(max)
 As for inductive loads (e.g. relays and Contactors), should be equipped with surge absorption circuit; such as: RC
absorption circuit (note the leakage current shall be less than that of the control contactor or relay current), varistors,
or diode etc. (for DC magnetic circuit, must pay attention to the polarity when installing). The component of the
absorption circuit is to be mounted near the coil of the relay or contactor.
