Simulator provide a simple way to test your program before connecting the

module to a real system.

1. Connect the MMC120 to the DCS120-Win software

Many of the following steps assume the DCS120-Win software package is used in

conjunction with the MMC120 to set up the system. Therefore, one must first

connect DCS120-Win with the MMC120 using a serial cable.

For information on the cable required, see

Wiring Notes

.

To change your serial port, see

Selecting a Serial Port to Use

.

2. Wire the Transducers and Drive Outputs

The MMC120 supports single ended and differential transducers. For more

information see

Wiring Notes

.

Caution: Leave power to the motors and/or hydraulics disabled until instructed

to power them on later in this procedure.

3. Configure the Transducers

The MMC120 supports a wide range of Magnetostrictive Displacement

Transducers. To select the type of the transducer and polarity of the drive output,

the following settings can be changed:

Support for Pulse-Width Modulated or Start-Stop MDTs.

Support for between 1 and 15 recirculations on PWM MDTs.

Support for using either edge of a Start-Stop pulse. This is required to support

some Balluff transducers.

Support for reversing the drive output in software.

Each of these settings can be changed using the

Configuration word

axis

parameter; no jumpers are required. You need to set this parameter for each axis

used; refer to the

Configuration word

topic for instructions on using this parameter.

4. Test the Transducer and Drive Connections of Each Axis

Caution: Open loop operation, which this procedure uses, ignores all limits! Be

prepared to remove drive power. Great care must be taken to avoid accidents

when starting the motion control module for the first time. The most common

accident is a runaway, where the motion controller tries to go to a position

beyond the physical limits of an axis.

A. Ensure that the hydraulic or motor power is off, and all drive output connectors

on the MMC120 are disconnected.

B. Start DCS120-Win and ensure it is Online with the MMC120.
C. Connect the MMC120 drive output to the motor or hydraulic valve of the axis

being setting up.

D. In DCS120-Win, with the cursor on the axis you want to adjust, enter ALT+R

to restore the null. Enter 0 (zero) in the COMMAND VALUE field of the axis,
