Model 1000AR Regenerative Brushless DC Motor Control INSTALLATION AND OPERATION INSTRUCTION MANUAL JUNE, 2001
Model 1000AR Installation and Operation Manual PAGE 1 INTRODUCTION W HAT I S A G E N E S I S S E R I E S B R U S H L E S S D C D R I V E ? The GENESIS series of Brushless DC (BLDC) motor controls (drives) were developed to operate very large Brushless DC motors. Large BLDC motors were first made by POWERTEC Industrial Corporation in the late 1980’s. POWERTEC was acquired by Powertec in 1993. Small BLDC motors have been in use for many years.

Model 1000AR Installation and Operation Manual PAGE 3 RE GE NE RATIV E V E RS US NON-RE GE NE RATIV E OP E RATION Traditional AC induction motors and brush-type DC motors have windings on the rotor. They also have stationary windings on the frame that produce magnetic fields if we energize them. When the motor rotates, the windings move through the magnetic field. If we externally force the shaft to turn, this movement through magnetic fields produces a potential at the motor’s power terminals.

Model 1000AR Installation and Operation Manual PAGE 15 HOW DO I … CONNE CT THE MOTOR TO THE 1 0 0 0 AR DRIV E ? We ship every drive from the factory with A STANDARD CONNECTIONS card. Connect the motor lead marked T1 to the T1 terminal on the drive. Connect the T2 lead to T2 on the drive, and connect T3 to T3. Other connections to T1, T2, and T3 at the motor will vary with the motor. The motor will not operate if the power wires from motor to drive are not in the proper order.
Page 16 Model 1000AR Installation and Operation Manual RE G E NE RAT I V E RE S I S T O RS Regenerative motor controllers require a method of handling energy that is generated by the motor and returned to the drive. Traditionally, this has been handled by two methods: (1) using the power lines as a power sink by dumping excess energy back into the power source, and (2) dissipation as heat.

The bus loader mounts on the lower left-hand side panel and it plugs directly to the driver board. The power components for the bus loader are on the lower third of the chassis.
Page 18 Model 1000AR Installation and Operation Manual C O N TAC TO R S P E C I F I C ATI O N S If you want to operate an Output or DB Contactor directly from the Model 1000AR, you must choose a coil that draws less than 50 milliamps DC. The Output Contactor drawing on page 11 shows the connections for direct operation of the contactor (use the same connections for Dynamic Braking). The coil must be 48VDC and draw less than 50 ma DC (2.4 Watts).

Model 1000AR Installation and Operation Manual PAGE 23 The RUN relay contact at TB2 terminals 7 and 8 is a dry contact rated at 1 Amp (Resistive load) at 125VAC. You may use it in an external circuit as long as the voltage does not exceed 125 VAC (limitation of the terminal strip). You may use an auxiliary relay if you need more power, or if you need more contacts, as shown in the drawing at the left. You should use a 48VDC coil (highly recommended) since this reduces the burden on one supply.

Model 1000AR Installation and Operation Manual PAGE 25 HOW DO I … CO NNE CT AN ANALO G S P E E D RE F E RE NCE ? The analog speed reference for the Model 1000AR is 10 VDC to +10 VDC with the positive connection on TB2 terminal 5 and the common connection on TB2 terminal 16. Voltages less than -10 VDC become non-linear and voltages greater than 10 VDC become non-linear. The input impedance is about 100K.
Page 26 Model 1000AR Installation and Operation Manual D I G I TAL M O D E N O TE S Since the Brushless DC motor control system is inherently digital, the performance in the digital mode of operation far exceeds the performance in the analog mode. In the digital mode the control and motor respond to a frequency signal fed to the control from an external source. In the digital mode, we use the same digital control circuitry for the speed control as we do in the analog mode.
Model 1000AR Installation and Operation Manual PAGE 27 HOW DO I … C O N N E C T A D I G I T AL S P E E D R E F E R E N C E ? Apply +24VDC to TB1 terminal 10 (TB1-10) with respect to TB1-9 to operate the Model 1000 with a digital reference. Terminal 9 on TB1 is NOT the same as drive common. A jumper from TB2-10 will NOT switch to digital mode unless you connect TB1-9 to a drive common terminal (TB1-16). With +24VDC on TB1-10, a pulse train at TB111 (with respect to TB1-9) commands the motor movement.
Page 28 Model 1000AR Installation and Operation Manual AN AL O G V E R S U S D I G I TAL O P E R ATI O N The choice between ANALOG and DIGITAL operation comes down to performance. In ANALOG mode, a voltage sets the speed of the motor. Due to analog component tolerances, the best accuracy you can expect is on the order of +/- 1%. It is typically 0.1% or better. The biggest problem with Brushless DC is not the following of an analog source. It is the obtaining of a clean and stable analog source to follow.
Model 1000AR Installation and Operation Manual PAGE 29 HOW DO I … C O N N E C T A D I G I M AX ® ? ® The DIGIMAX is a crystal-based Speed or Ratio controller. It creates a train of pulses to command the movement of a motor when the drive is operating in digital speed mode. A suitable train of pulses applied at TB1 terminal 11 (with respect to TB1-9) of the Model 1000 commands the drive to turn the motor 3° for each pulse.

Since the Model 1000AR is a regenerative drive (see page 3), the motor does not coast when the speed reference is reduced. The deceleration ramp is enforced by removing energy from the motor. This is accomplished by treating the motor as a generator and applying a load to it.
