A Summary of Changes to the MPA-03/06-SL manual (575-00031)
Rev A to Rev B (June 1999)
•Removed all references to “Custom Servo Motors”.
•Corrected “Simulated Encoder Signals” section.
Rev B to Rev C (January 2001)
•Changed the first paragraph under “Warranty and Service” to read:
The amplifier is warranted to be free from defects in workmanship and materials for a period
of two years from the original shipment by MTS Automation.
Rather than:
The amplifier is warranted to be free from defects in workmanship and materials for a
period of 18 months from the original shipment by MTS Automation, or 12 months in
service, whichever comes first.

Application
This manual is designed to help you install the MaxPlus™ MPA-03/06SL amplifier.
Unpacking and Inspection
Carefully unpack the amplifier and inspect it for visible damage. Check items against the
packing list. Report any missing or damaged items to your supplier.
Warranty and Service
The amplifier is warranted to be free from defects in workmanship and materials for a period
of two years from the original shipment by MTS Automation.
During the warranty period, a defective amplifier unit will be repaired or replaced as outlined
below.
Before requesting return authorization, please try to verify that the problem is within the
amplifier, and not with external devices.
To arrange for repair or replacement, please contact:
MTS Automation Customer Service
(507) 354-1616
(800) 967-1785
Monday–Friday, 8:00–4:30 Central Time
• You must provide the model and serial number from the labels on the amplifier.
• You must provide an explanation as to why the unit is being returned.
• You will be issued a return authorization number which must be marked on the
return shipment and on all correspondence.

Warranty and Service (continued)
Service Under Warranty
• Return your defective unit, freight prepaid, and it will be repaired and returned within two weeks of
receipt via regular UPS, freight prepaid.
• Upon request, a factory-repaired replacement unit will be sent via regular prepaid UPS, within 4
working days. Next day shipment for overnight delivery, freight collect, is available at an expediting
charge of $100. The defective unit is to be returned via regular UPS, freight prepaid, upon your
receipt of the replacement.
Non-Warranty Service
• Return your defective unit, freight prepaid, and it will be repaired on a time and material basis and
returned within three weeks of receipt.
• OR contact your local distributor or MTS Automation Customer Service for a factory-repaired
exchange unit, which is available at a flat rate price, assuming the defective unit is in repairable
condition and is returned freight prepaid. Next day shipment for overnight delivery, freight collect, is
available at an expediting charge of $100.
General Provisions
Except as specifically modified by this warranty statement, all MTS Automation Conditions of
Sale and Warranty shall apply.

Introduction
These amplifiers are designed to be used with high performance brushless servo motors.
Care has been taken to assure robust operation. Design consideration for electrical transients
have been implemented on the ac power input and all of the I/O lines. The amplifier operates
over an ac voltage range of 80 to 260 Vac from 45 to 65 Hz. The motor feedback device is a
resolver to assure normal operation at elevated motor temperatures of 115°C for the case,
and 155°C for the motor windings. The resolver allows for both position and velocity
feedback. The motor is further protected by a thermal shutdown thermostat in the motor
windings. The amplifier power switching devices are state of the art IGBT modules. The logic
supply is a switch mode design reducing undesired heat. LED indicators for diagnostics are
provided.
Features
• Efficient power conversion
• High frequency switching
• Resolver feedback
• Simulated encoder signals
• ± 10 volts for maximum velocity or torque
• 24 volt I/O for Enable Velocity/Torque mode
• Differential analog channel for command
• LED diagnostic indicators
• Motor thermal protection
• AC, I/O and bridge transient suppression
• Totally self contained space efficient design
• Simple screw terminal interface
• AC inrush protection
• Simple one turn visual adjustments
• MOV overvoltage Bus surge protection

Motor/Amplifier Speed and Load
Relationship
The motors maximum speed is
dependent on the bus voltage and
motor KE by the following relationships.
In the Velocity Mode of operation, the
TAC Gradient also would limit the
speed.
(AC Input)/(Motor KE vrms) = Max no load speed.
Max no load speed *.75 = Maximum speed at continuous full
load.
