Connect the other end to the GPIB interface in your PC. Figure 7. GPIB (IEEE-488) Interface ABOUT THE GPIB INTERFACE (General Purpose Interface Bus) D1 1 13 D5 Magtrol instruments use the GPIB (IEEE-488 Standard) for computer-to-instrument interfacing because: • The GPIB parallel interface is faster than serial interfaces. • The GPIB enables testers to access up to 15 instruments on one port. Because typical motor testing requires that at least five separate parameters must be synchronized, a system of easy, fast access to more than one instrument is essential. • The GPIB has rigid data formatting and hardware standards. These standards help to ensure that all functions will work properly when the hardware and software are installed.

An interface card and driver software must be installed. Magtrol recommends National Instruments Corporation hardware and software. An IEEE-488 cable must be installed between the computer and the 6200. INSTALLING CABLE THE GPIB (IEEE-488) CONNECTOR CHANGING THE GPIB PRIMARY ADDRESS Each instrument serviced by the GPIB has its own Primary Address code, which enables the computer to obtain readings from the instrument. The factory default setting on the 6200 is 15. Some PC interfaces can access from one to fifteen 4-bit primary addresses. Other interfaces can access as many as thirty-one 5-bit primary addresses. The 6200 uses the 4-bit format. 1. Press the SHIFT button and release. 2. Press SETUP. 3. Press DOWN " twice.

Connect one end of a high-quality, double-shielded cable to the 6200 GPIB connector. 11 Chapter 4 - The 6200 with a PC (Remote Control) CHECKING THE 6200-TO-PC CONNECTION NOTE: Make sure that the 6200 and its host computer are communicating before acquiring data. Magtrol Model 6200 Dynamometer Controller/Readout 2. Set the timeout for at least one second, if you are asked to set a communication fault delay timeout. • If the communication fault delay timeout is too short, or if the computer resets the interface too quickly, the host instrument may stop responding. 6200 COMMAND SET 1. Make sure the primary address is set correctly for the 6200. 2. Set the input variable to 15 characters (13 variable characters and the two required data termination characters CR and LF. (See “Programming” in this chapter.) 3. Issue output data command "OD" and read 15 characters according to the instructions for your GPIB interface. Desired results: • Torque/speed data will be returned NOTE: If the desired results did not occur, please see Chapter 6 Troubleshooting. PROGRAMMING NOTE: Check the manual provided with your software for full instructions. 1. Use the following information to answer the formatting questions asked when installing your GPIB software. • All GPIB data acquisition systems requires the use of data termination characters. The 6200 uses the GPIB standard termination characters "Carriage Return (CR)-Line Feed (LF)." Provide them in that order. CODES FOR CR - LF BASIC 12 H EX D EC CR = CHR$(13) 0D 13 LF = CHR$(10) 0A 10 When entering a command code: 1. Type all characters in uppercase ASCII format. 2.

A Radio Shack #26-152 cable and #26-264 null modem adapter are known to work. The null modem adapter must be used on the computer end of the cable. 15 5 - Calibration CLOSED-BOX CALIBRATION The 6200 features closed-box calibration. The advantage of closed-box calibration is that the user does not have to disassemble the case or make mechanical adjustments. However, the calibration of the Accessory Torque Output must be done internally with Offset and Gain trim pots. The Torque readout and Auxiliary Input can be calibrated using external reference sources. Correction factors for Offset and Gain are stored in nonvolatile memory. They remain in effect until the user or the calibration house updates them. The front panel displays the actual values for the ZERO and GAIN correction factors. Record these values before calibration. In the unlikely event of a Controller/ Readout failure, it can re-initialized by pressing and holding the STORE and RECALL buttons while turning the power on. All internal memory and setups will be lost. After re-initializing, reprogram the GAIN and ZERO values into memory. CALIBRATION SCHEDULE INITIAL CALIBRATION PROCEDURE NOTE: Record the actual correction factors displayed before proceeding with calibration. 1. Allow the 6200 to stabilize in an environment with: • An ambient temperature of 18°C to 25°C • Relative humidity less than 80% 2. Turn on the 6200. 3. Allow the 6200 to warm up for at least 30 minutes. 4. Enable the calibration mode as follows: • Turn instrument power OFF • Press in and hold the UP ! and DOWN " arrow buttons simultaneously • Turn instrument power ON 5. Continue pressing the UP ! and DOWN " arrow buttons until the display shows the software revision date. 6. Press the SHIFT button once. NOTE: To exit CALIBRATE mode without making any changes, press the SHIFT button six times. Calibrate your 6200: • After any repairs are performed • At least once a year; more frequently to ensure required accuracy TORQUE OFFSET BASIC CALIBRATION PROCESS 1. Connect the external voltage reference common to Pin 13 of the dynamometer input connector. The basic calibration process consists of four procedures which must be performed them in the following order: 2. Connect the external voltage reference high to Pin 14 of the dynamometer input connector. 1. Initial Procedure 3. Apply +2.000 VDC. 2. Torque Offset and Gain 4. Press the DISPLAY button. 3. Accessory Torque Output Offset and Gain 5. Adjust the gain by turning the Decrease/Increase Dial until the displayed voltage equals the reference voltage. 4. Auxiliary Input Offset and Gain To calibrate the 6200, you will need: • External voltage reference of 0 to 5 Volts DC • Digital multimeter (DMM) with VDC accuracy of 0.05% or better 16 NOTE: AND GAIN The magnitude of change per revolution can be increased by pressing the UP ! button or decreased by pressing the DOWN " button.

ACCESSORY TORQUE OFFSET ALTERNATE CALIBRATION PROCEDURE AND GAIN 1. Connect the DMM common to Pin 4 of the Accessory Torque-Speed Output connector. 2. Connect the DMM high to Pin 2 of the Accessory Torque-Speed Output connector 3. Apply 0.000 VDC 4. Adjust R24 (OFFSET) on the circuit board for 0 mVDC on the DMM. 5. Apply +2.000 VDC. 6. Adjust R25 (GAIN) on the circuit board for +2.000 VDC on the DMM. AUXILIARY INPUT OFFSET AND GAIN 1. Press the SHIFT button once. Display indicates AUX INPUT calibration. 2. Connect the external voltage reference to the Auxiliary Input BNC connector. 3. Apply +5.000 VDC. 4. Press the DISPLAY button. 5. Adjust the gain by turning the Decrease/Increase Dial until the displayed voltage equals the reference voltage. NOTE: The magnitude of change per revolution can be increased by pressing the UP ! button or decreased by pressing the DOWN " button. The 6200 can also be calibrated by using a certified dynamometer, calibration beam, and weight instead of an external voltage reference. NOTE: Magtrol suggests you do NOT use this method. By using the alternate calibration procedure, you are calibrating the 6200 to a specific dynamometer, not to a reference standard. If you connect the 6200 to a different dynamometer, the resulting torque reading may be incorrect. 1. Connect the chosen dynamometer to the 6200 using the 14-pin signal cable and the 2-pin brake cable. 2. Attach the calibration beam to the dynamometer shaft. 3. Enter the calibration mode. 4. Press the BRAKE ON/OFF button ON to apply full loading to the dynamometer. 5. Hang the weight on the calibration beam pin and level the beam. 6. Press the DISPLAY button. 7. Adjust the gain by turning the Decrease/Increase Dial until the displayed voltage equals the reference voltage. 6. Apply 0.000 VDC. 7. Press the UNITS DISPLAY button. 17 Chapter 5 - Calibration NOTE: The magnitude of change per revolution can be increased by pressing the UP ! button or decreased by pressing the DOWN " button. Magtrol Model 6200 Dynamometer Controller/Readout Figure 9. Alternative Calibration Torque = Weight (W) x Distance (D) Weight (W) = Torque / Distance (D) D 8. Remove the weight for ZERO adjustment. 9. Press the UNITS DISPLAY button. 10. Adjust the Increase/Decrease Dial until the display indicates 0 mVDC. NOTE: The mV output of the dynamometer will be equivalent to the Weight times Distance on the calibration beam, disregarding any decimal point. Example: Magtrol’s HD-400-6 Dynamometer has a fullscale torque of 40.0 oz.in. The distance from the center of the dynamometer shaft to the pin on the calibration beam is 5 inches. Placing an 8 oz. weight on the pin will produce a torque of 40.0 oz.in. The mV output of the dynamometer will be equivalent to 8 oz. multiplied by 5 inches, yielding an output signal of 400 mV. 11. Repeat steps 5 through 10. 12. After completing calibration: • Press the BRAKE ON/OFF button OFF to remove loading from the dynamometer. 13. Remove the calibration beam from the dynamometer shaft. 14. Proceed with your desired motor testing. 18 W Be sure the shaft flat is facing down, tighten the cal-beam screw against the shaft flat only. 6 - TTroubleshooting roubleshooting PROBLEM REASON SOLUTION Returned data indicates COMMAND ERROR Command does not match the unit's programmed set of instructions Use correct command and format Mechanical power reads much higher or lower than expected Torque units are incorrect No GPIB communication Setup error and/or hardware fault No RS-232 communication Setup error and/or hardware fault Dynamometer shaft does not turn smoothly when BRAKE is OFF Salient poles were set up on the rotor by having brake current applied with no shaft rotation Set torque input units to match the specifications on dynamometer nameplate Check: • GPIB address of Controller/Readout • GPIB cable: should be functioning and attached to Controller/Readout and computer interface card Check: • Baud rate of Controller/Readout • Pinout of serial cable • Cable attachment to Controller/Readout and serial interface port of computer Start the motor and bring up to speed.
