3.3 Analog Inputs
SSDC series drive has two analog signal inputs which can accept signal range of 0-5V, 0-10V,
±
5V and
±
10V. The drive can be configured to operate at velocity mode or position mode that is
proportional to the analog input.
Use the Step-Servo Quick Tuner to configure the input range, offset, deadband and noisy filter
frequency.
SSDC series provides a +5V/100mA limit power supply that can be used to power external
devices such as potentiometer. It is not the most accurate supply for reference, for more precise
readings use an external supply that can provide the desired accuracy.

3.4 Encoder output
SSDC has differential encoder outputs (ENC A+/-
，
ENC B+/-
，
ENC Z+/-), with 26C31 line driver,
20 mA sink or source current in max. These signals can be connected to the motion controller to
be a feedback of the motor position.
