Servo Amplifier Power Input

The J3 connector on the servo amplifier (see outline drawing for connectors) is the power input connector.
3.4.2

Servo Amplifier Command Input

The J1 connector on the servo amplifier is for command signals. Apply a differential waveform signal to this
connector within the specified range of ±5 V. The input impedance is 100 kΩ. If a single-ended command is used,
either Pin 1 or Pin 2 may be grounded.
The scale factor for these commands is 1.3 mm/V.

BLINK Motor Connection to Servo Amplifier

Note: Amplifiers are individually tuned to specific units. Look for a label indicating the matching serial number
on the bottom of the amplifier.
