4-16 Diagnostics, Troubleshooting, and Start-Up Guidelines
Step 2. Using the Monitor I/O screen, force a value within the range configured to
each UDC register being output on the meters.
Step 3. Use a voltmeter to verify that the signal on the terminal points (-10V to +10V)
of each meter port is proportional to the value in the corresponding register.
Step 4. Unforce the registers being output on the meter ports to zero.
4.7.8.6 Testing PMI Regulator Meter Ports
This section describes how to test the PMI Regulator meter ports. Use the AutoMax
Programming Executive software Monitor Setup UDC/PMI screen.
Step 1. Select parameter 19 (Application Data) for all of the PMI Regulator ports
being used. Set the minimum and maximum values to -2048 and +2047,
respectively.
Step 2. Return to the I/O Monitor screen. Display register 106/1106 (PMI_DA%).
Step 3. Check each PMI Regulator meter port being used as follows:
a. Write a value between -2047 to +2047 to register 106/1106.
b. Use a voltmeter to verify that the signal (-10V to +10V) on each set of
Meter Port terminal points is proportional to the value written in step b
above.
4.7.9 Performing Uncoupled Motor Tests (Vector)
The following tests are performed with the motor uncoupled from the load. Ensure
that the limit values entered through the parameter entry screens are correct.
Step 1. Verify that the parameter screen information (Power Module data, motor
data, speed feedback data, and meter port setup) is correct.
Step 2. Calculate the values for local tunables STATOR_R_E4% (stator resistance),
STATOR_T_E4% (stator time constant), and STATOR_IZ_E1% (no load
stator current) by setting the Enable Tuning bit (register 100/1100, bit 1,
PMI_TUN@). The Automatic Tuning Complete bit (register 200/1200, bit 1,
PMI_ATC@) will be on to indicate the values have been calculated. Reset
the PMI_TUN@ bit after the test is complete.
Note that if you are using a high slip motor, the value calculated for the
tunable STATOR_IZ_E1% may not be correct. Appendix G in the SA3100
Drive Configuration and Programming manual (S-3056) provides the
procedure to verify the value in this tunable if you are using a high slip motor.
Step 3. Perform the resolver gain calibration procedure. This procedure is described
in the PMI Regulator instruction manual (S-3057). The Resolver Gain
Calibration Completed bit (register 201/1201, bit 6, RES_GAN@) will be set
to indicate the procedure is complete. Check the value in the local tunable
RES_GAN%. Large gain values (close to 255) may indicate a problem with
the resolver wiring or connections. Refer to the SA3100 Drive Configuration
and Programming instruction manual (S-3056) for a list of the resolvers that
may be used with SA3100 drives.
