The MDrive has 2 logic inputs which are located on connector P1. These
inputs control the ON/OFF state of the internal clock pulse generator and the
direction of motor rotation. Each input is internally pulled-up to +5 Volts and
may be connected to sinking outputs on a controller such as the IMS LYNX
or a PLC. These inputs are:
There are also three connections for a Joystick or a Potentiometer. These are:
The Speed Control input may also be interfaced to a PLC 15 - 25 kHz PWM
output or a 4 - 20mA or 0 - 20mA output analog device. If a 4 - 20mA or 0 -
20mA device is used, the corresponding input mode MUST be selected on the
Analog Speed Control Interface software.
The two figures below illustrate Interface options for the Speed Control
Version of the MDrive.
