HAPTER Introduction The AutoMax Distributed Power System SA500 AC Power Modules provide AC power to, and control of, brushless motors and squirrel-cage induction motors from 1–15HP. Each Power Module contains the Power Module Interface (PMI) Regulator printed circuit board and the inverter used to convert DC power to AC power for the motor. Depending upon their power requirements, up to six Power Modules can be daisy-chained together and operated from one SA500 DC Bus Supply, which provides the Power Modules a nominal 325 VDC input power.

2.2.1 Fiber-Optic Ports Transmit (XTM) and receive (RCV) ports are provided on the faceplate of the Power Module for connection to the fiber-optic link with the UDC module in the AutoMax rack. The Power Module is shipped with dust caps covering the fiber-optic ports. To prevent dust accumulation and the resulting loss of signal integrity, the dust caps should not be removed until the fiber-optic cables are installed, and should be replaced if the cables are disconnected.
RIGHT SIDE VIEW POWER RAIL FUSE Figure 2.3 – Location of Rail Fuse on PMI Regulator PC Board 2.2.3 Resolver Feedback Connector The faceplate connector labeled “RESOLVER FEEDBACK” is used to connect the resolver to the Power Module. This connector will also accept a signal from an analog tachometer or other analog field device as long as the signal is within the correct voltage range.
ATTENTION: For brushless motor applications, changing any resolver wiring, breaking the resolver coupling, replacing the resolver, or replacing the motor and resolver for any reason requires that the shaft alignment test be performed again. Resolver wiring changes always affect shaft alignment.

If any of these events occurs, the PMI will wait for 100 msec and then turn off the MCR output. If the RPI signal is removed, the MCR output will be turned off and gate power will be removed under hardware control within approximately 0.5 second to provide an additional level of protection.
HAPTER Power Module Electrical Description DC input voltage to the Power Module is supplied by a DC bus, normally the SA500 DC Bus Supply. The inverter bridge in the Power Module converts the constant potential DC voltage from the DC bus to three-phase AC power for the motor. The inverter bridge consists of six bi-polar transistors.
The PMI will automatically request its operating system from the UDC module as soon as communications are established over the fiber-optic link. After the operating system has been downloaded from the UDC module (a process that takes approximately 0.5 seconds), the PMI Regulator will send a feedback message. The UDC module will respond with a command message and configuration data.
bits resolver data revolution counter Figure 3.2 – Resolver Data Format (14-Bit Mode) The PMI produces a nominal 26 volt rms 2381 Hertz sine wave reference output signal which is capable of driving a 500 ohm load. The stator signals (sine and cosine) are input through a matched isolation transformer pair.

Step 1. Mount the Power Module. Power Modules are designed to be mounted vertically on a flat surface using M5 or #10 screws. The holes in the top flanges are key-hole shaped and the lower hole is U-shaped to facilitate mounting.
Page 33
ATTENTION: To avoid the danger of an electrical shock or burn, only qualified personnel should install or service this equipment. Disconnect all power before working on this equipment. Dangerous voltages may exist after power is removed. Check the DC Bus Supply voltages each time power is removed before servicing.
4.3 Fiber-Optic Connection ATTENTION: Turn off, lock out, and tag power to both the rack containing the UDC module and to its corresponding PMI hardware before viewing the fiber-optic cable or transmitter under magnification. Viewing a powered fiber-optic transmitter or connected cable under magnification may result in damage to the eye.

4.6.1.1 Resolver Calibration The resolver input can be used with X1 and X2 resolvers with cable distances as shown in table 4.4. The PMI contains circuitry to synchronize the reference waveform to within 10 degrees of the returning waveforms. This synchronization corrects for any phase shift which can occur between the reference and stator signal (i.e., stator signals lagging the reference) due to unbalanced wire impedance.
Balance Calibration The balance calibration procedure is initiated by setting UDC register 101/1101, bit 6 (RES_CAL@) after turning the drive on. The procedure takes from a few seconds to one minute to complete. It must be performed while the resolver is rotating at 5 RPM minimum speed (speed does not have to be constant).
The result of the resolver alignment test is written to the reserved tunable RES_ALN% by the PMI. The value in the variable represents the offset. See the SA500 Drive Configuration and Programming instruction manual (S-3044) for more information about the RES_ALN% tunable variable. The alignment test is commanded by the programmer by setting bit 1 in register 100/1100.
Resolver Restrictions The PMI cannot discriminate between X1 and X2 resolvers. It only detects electrical rotations. One mechanical rotation is equivalent to one electrical rotation for an X1 resolver and two electrical rotations for an X2 resolver. The practical limit of electrical speed that the module can detect is dependent both upon the resolver selected and upon the resolution selected during drive parameter configuration.

Step 14. Set the application’s Speed Reference equal to 1023 (reference point 2, STATOR_IZ1E2%). Do not change the value in reference point 1, STATOR_IZ0E2%. Step 15. Start the drive. The motor should come up to speed and go into stable run. Record the motor voltage.

Step 3. Disconnect the DC Bus Supply wires from the Power Module’s POS, NEG, and GND terminals. Disconnect the motor leads from the U, V, and W terminals on the Power Module. Step 4. Remove the screws that attach the Power Module to its mounting surface. Step 5.
HAPTER Diagnostics and Troubleshooting The PMI monitors the Power Module for numerous fault and warning conditions. Faults cause the Power Module transistor gate firing signals to be turned off and bring the motor to a coast-to-rest stop. Warnings indicate problems in the Power Module and PMI, but do not shut down the drive.

Vcc Power Supply Undervoltage (Bit 3) LED indicator: P.M. FLT Bit 3 will be set if the input to the +5V supply for the PMI Regulator drops below the necessary voltage required to maintain regulation. Error code 1019 will also be displayed in the error log of the UDC task in which the fault occurred.
UDC Run Fault (Bit 14) LED indicator: N/A Bit 14 will be set if the UDC task stops while the minor loop is running in the PMI Regulator. Error code 1014 will also be displayed in the error log of the UDC task in which the fault occurred.
PMI Communication Warning (Bit 15) Bit 15 will be set if a fiber-optic communication error is detected between the PMI and the UDC module. Communication errors in two consecutive messages will cause a drive fault. 5.3 Power Module Failure The SA500 Power Module has no user-serviceable parts with the exception of the rail fuse described in section 2.2.2.

PPENDIX Custom DC Bus Supplies The Auxiliary DC Bus Disconnect Panel can be used to facilitate the use of custom DC bus supplies. This panel supplies the necessary capacitance for the Power Module so that bus inductance, normally a concern in applications in which the DC bus supply is not near the Power Module, does not have an adverse affect on Power Module operation.
