DC Digital Motor Drive

Full-wave DC motor control for permanent-magnet motors · 115 Vac in / 0–130 Vdc out · PLC compatible

Board-level drive module

Overview

Built for bi-directional indexing

A full-wave DC motor control for permanent-magnet motors, designed especially for bi-directional indexing applications. Motor response is not subject to the 16 ms AC zero-cross variations associated with SCR and triac drives.

100% solid-state design with optically isolated control inputs, modular connectors for ease of service, and connections for an optional brake resistor and optional forward and reverse speed controls.

Directly compatible with PLCs
Instant forward / reverse
Auto brake when powered, not enabled
Free-wheeling when power is off
Can operate as a frequency drive
On-board or external speed adjustment
