Part III Appendix
Description of Self-Test Items 243
Test the UART communication between the multifunctional FPGA and the PHV Arm. Read the
PHV firmware version and build version.
Test failure analysis
If the test result is Error, the drive malfunctions.
If the test result is FAIL, the communication between the multifunctional FPGA and the PHV serial
port fails.
Troubleshooting suggestion
a If the test result is Error, restart the equipment and re-perform the self-test. If the problem
persists, recover the equipment.
b If the test result is FAIL, replace the main board.
2.12 Z0210 Program-Controlled Power Voltage
Test for the PHV Module
Upper-level test item
PHV Module Communication Test
Test content
On the multifunctional FPGA, set four levels for the PHV program-controlled voltage. Read and
check whether the voltage values at the four levels are within the specified range.
Test failure analysis
If the test result is Error, the drive malfunctions.
If the test result is FAIL, the PHV voltage setting is improper.
Troubleshooting suggestion
a If the test result is Error, restart the equipment and re-perform the self-test. If the problem
persists, recover the equipment.
b If the test result is FAIL, replace the main board.
2.13 Z0211 Fixed High Voltage Test for PHV
Module
Upper-level test item
PHV Module Communication Test
Test content
Enable the fixed power voltage ±100 (HV voltage) for the PHV board. Obtain the monitored board
voltage through the UART of the PHV ARM and check whether the voltage is within the specified
range.
Test failure analysis
If the test result is Error, the drive malfunctions.
If the test result is FAIL, the fixed high voltage does not meet the requirements.
