Danaher Motion Superior Electric Introduction
SLO-SYN SS2000MD7 & SS2000MD7-128 1
1. INTRODUCTION
It is important that you understand how this SLO-SYN® SS2000MD7
Translator/Drive is installed and operated before you attempt to use it.
We strongly recommend that you read this manual completely
before proceeding with the installation of this unit.
This manual is an installation and operation guide to the SLO-SYN
SS2000MD7 (MD7-128) Translator Drive. Section 1 provides an
overview of the drive and its features. Section 2 lists the steps
necessary to place the drive into operation. General wiring information
and the physical mounting of the unit and connections to the drive are
covered in Section 3.
The complete specifications provide easily-referenced information
concerning electrical, mechanical, and environmental requirements as
well as information for setting the motor current level.
Torque versus speed characteristics with appropriate SLO-
SYN stepper
motors are shown in Section 5. Troubleshooting in Section 6 provides
procedures to follow if the Translator/Drive fails to operate properly.
1.1. Product Features
The SLO-SYN SS2000MD7 (MD7-128) Translator/Drive is a bipolar,
speed adjustable, two-phase PWM drive that uses power MOSFET
devices. The MD7 is set to operate a stepper motor in 1/2, 1/10, 1/25,
or 1/100 microsteps. The MD7-128 is set to operate a stepper motor in
full, 1/16, 1/64, or 1/128 microsteps. The maximum running speed is
3,000 rpm. To reduce the chances of electrical noise, the control signals
are optically isolated from the drive circuit.
l UL-recognized under Component Program, File #E146240
l Switch-selectable current levels of 1 through 7 amps
l Full short-circuit protection (phase-to-phase and phase-to-ground)
l Undervoltage and transient overvoltage protection
l Thermal protection
l Efficient thermal design
l Optically-isolated inputs
l Current and Windings Off reduction capabilities
l Switch-selectable step resolution
l Compact size
l Sturdy all aluminum case

Quick Start Danaher Motion Superior Electric
2SLO-SYN SS2000MD7 & SS2000MD7-128
2. QUICK START
The following instructions are the minimum steps necessary to make
your drive operational.
Always disconnect the power to the unit and be certain that the
"PWR ON" LED is OFF before connecting or disconnecting the
motor leads. FAILURE TO DO THIS RESULTS IN A SHOCK
HAZARD AND MAY DAMAGE THE DRIVE.
Always operate the unit with the motor and drive enclosure
GROUNDED. Be sure to twist the wires together for each motor
phase as well as those for the DC input. Six twists per foot is a
good guideline.
1. Check to see that the motor is compatible with the drive. Refer
to Section 4.4 for a list of compatible motors.
2. Set the correct current level for the motor per the instructions
in Section 4.5. Heat sinking is required if a current of 4
amps or higher is used.
3. Select the appropriate step resolution and set the switches
(Section 4.6).
4. Wire the motor per Section 3.2.
5. Connect the power source to the DC input terminal strip. Be
sure to follow the instructions for connecting the filter
capacitor as instructed in Section 3.2.
If the motor operates erratically, refer to Section 5.
Clockwise and counter-clockwise directions are properly oriented
when viewing the motor from the end OPPOSITE the mounting
flange.

3. INSTALLATION
3.1. Mounting
The SLO-
SYN drive is mounted by fastening its mounting brackets to a
flat surface (shown below). If the Heat Sink Assembly (part number
221576-001) is mounted against a bulkhead, apply a thin coating to
thermal compound between the heat sink and the mounting surface
before fastening the unit in place. DO NOT use too much thermal
compound. It is better to use too little than too much.

Case temperature should not exceed +70° C (+158° F). A heat
sink, such as Superior Electric Heat Sink Assembly 221576-001,
must be used when the drive is operated at a current setting of 4
amps or more. In this case, mount the unit upright (with the
cooling fins vertical) or proper cooling will not occur. Airflow
should not be obstructed. Forced air cooling may be required to
maintain temperature within the stated limits.
