Summary

Introduction

Power Supply Considerations

Requires a single power supply of +15V to +65Vmax. Max current 32A continuous, 48A peak. Includes fuses for shunt and bus.

Current Mode Considerations

Fixed current gain 1.25A/V. ±10V input corresponds to ±12A current across the load. Note on back EMF.

Amplifier-Enable/Fault Polarity Selection

Configure controller for low-true enable signals. Green LED indicates power and enable. Red LED indicates fault (overheat).

Torque/Velocity Control

Direct torque or velocity control via I-variables in motor software setup. Example: PMAC1-Turbo.

Hardware Description

TB1: 8 Pin PMAC Interface Terminal Block

Provides the actual connection to the motors. Lists pinout for AMPOUT1-4.

TB2: 13-Pin Motor Amplifier Output Terminal Block

Connects analog command signals, amplifier-enable lines, and sends amplifier fault signal back to the controller.

TB3: External Power Ground

Single pin connector for Bus power reference (PGND).

TB4: External Power

Single pin connector for Bus power supply (A+65V).

TB5: Logic Power Terminal Block

Provides logic power connections: AGND, +15V, and -15V.

P1: 96-Pin Power Input Connector

Details pinout for the 96-pin power input connector, including PGND, +65V (bus), DB R+/-, AGND, A+15V, A-15V.
