This section shows examples of Servopack I/O signal connection to the host controller.
J J Interface for Reference Input Circuits
Analog Input Circuit
Analog signals are either speed or torque reference signals at the impedance below.
D Reference speed input: About 14 kW
D Reference torque input: About 14 kW
The maximum allowable voltages for input signals is ±12 V.
