If the test result is Error, the drive is abnormal.
If the test result is FAIL, the prompted voltage does not meet the requirements.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, replace the main board.
Z0210 PHV Communication Test
• Upper-level test item
Communication Test Between PC Module and MF FPGA
• Test Items
Test the UART communication between the MF FPGA and the PHV Arm. Read the PHV
firmware version and build version.
• Test failure analysis
If the test result is Error, the drive is abnormal.
If the test result is FAIL, the communication between the MF FPGA and the PHV serial port
fails.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, replace the main board.
Z0211 PHV Programmable Power Voltage Test
• Upper-level test item
PHV Communication test
• Test Items
On the MF FPGA, set four levels for the PHV program-controlled voltage. Monitor whether the
voltage values at the four levels are within the specified range through the UART of the PHV
ARM.
• Test failure analysis
If the test result is Error, the drive is abnormal.
If the test result is FAIL, the PHV voltage setting is improper.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, replace the main board.
