Page 6: Introduction
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. -

Page 12: Motors And Commutation
Motors and Commutation The amplifier can commutate 4-pole, 6-pole, 8-pole, and brush motors in its standard configuration and other factory options are practical. JP3 and JP4 allow for configuration changes. Drives are shipped set for 6-pole operation. Never change these jumpers with power on. -
Page 13: Diagnostic Indicators
Diagnostic Indicators MOTOR THERMAL FEEDBACK WIRING SHORTS POWER ON CONTINUOUS SIG BAL RESP CUR There are four faults that will reduce amplifier current to zero. INDICATION CONTINUOUS If a load condition exists that causes the amplifier to produce more than its continuous rating, this fault occurs. -
Page 14: I/O Wiring And Descriptions
I/O Wiring and Descriptions The amplifier has three inputs and two outputs. These inputs and outputs are designed to interface to a 24-volt logic system. The amplifier is shipped so that the operation of the inputs are as follows. With no wires connected to VEL/TORQUE, ENABLE, or START, the amplifier is disabled and normal operation will not occur. -

The simple guideline is to divide the KE into the AC input voltage. AC Input -------------- = MAX no load speed KE Motor This maximum speed must be derated by .75 at full load. TAC Gradient Limit If the drive is being used in the velocity mode, the TAC gradient, as determined by the R-D converter resolution jumpers, would limit speed.

Page 18: Analog Input And Adjustments
Analog Input and Adjustments There is one analog input channel for command. This has differential inputs and is summed with a TAC feedback differential amplifier that controls velocity if the Velocity Mode is selected. Normal operation of the command signal is to apply a + voltage (pin #9) with respect to GND (pin #11) and get clockwise rotation of the shaft. -
Page 19: Ac Input And Internal Protection
AC Input and Internal Protection A branch circuit disconnect must be provided in front of the drive. Model Single Phase MPA-03 SL 5 amps MPA-06 SL 10 amps AC power wiring must be consistent with any local codes, national electric codes, and be able to withstand the voltage current ratings applied. -
Page 20: Stator Wiring
The locked rotor stator current is equal to the drive's continuous rating, and for either low speed or locked rotor conditions, the stator must withstand this continuous rating. Model Locked Rotor MPA-03 SL 3 amps MPA-06 SL 6 amps It is acceptable and recommended that four conductor shielded cable be used. -
Page 21: Start-Up
Start-Up Once normal wiring is verified, power can be applied to the amplifier. Assure the input settings are what are required. Jumper default settings are for 6-pole motors. The ENABLE Input will disable the drive if it is not connected. The CUR and RESP adjustments are turned down (CCW). -
