General Provisions Except as specifically modified by this warranty statement, all MTS Automation Conditions of Sale and Warranty shall apply. 3 Introduction The 306 Spindle Amplifier was designed to be used with the MPM1902R-1368 spindle motor. This motor is wound in a WYE configuration with four windings in each leg. The legs are connected by a system of relay switches mounted on the side of the motor that change the motor KE and KT. This allows up to 10 horsepower in four speed ranges, eliminating the need for any complex mechanical gear reductions. The TAC output of the amplifier is scaled to the speed ranges as follows: Low Speed 1690 rpmTAC output = .69 volts Med Low Speed 21630 rpmTAC output = 1.63 volts Med High Speed 33300 rpmTAC output = 3.3 volts High Speed 45000 rpmTAC output = 5.0 volts The amplifier has overcurrent sensing which will cause the amplifier to shut down and produce a stall fault if the continuous current rating of the amplifier is exceeded by 20%. The stall fault also occurs if a speed variation between Command and actual TAC Feedback occurs. This is factory set to 20%. The amplifier also has an I/O selectable orient feature. This causes the motor shaft to rotate at a fixed rate of 1 rev per second in a CCW direction viewed from the shaft end of the motor. Ramping of the command input signal for a time period of 2 to 10 seconds is user selectable. A DIP switch allows ramping to be enabled and disabled through the I/O connector. An analog dc voltage output that is proportioned to the output current is also supplied.
