3.2.4 Interface Circuit
This section shows examples of servo drive I/O signal connection to the host controller.
■Interface for Analog Reference Input Circuit
Analog signals are either speed or torque reference signals at about 40kΩimpedance, and the maximum allowable
voltages for input signals is ±10V.
