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. WiretheTransducersandDriveOutputs
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,
