C-10 Description of Self-test Test Items
analyzes whether the waveform belongs to PHV1, and compares the signal-to-noise
ratio of the channel with others’.
 Analysis to test failure
The drive goes wrong if the test result appears Error.
The waveform that the channel transmits is incorrect if the information “Open circuit
emit receive channel: XXX” appears.
The transmission of the channel affects others’ if the information “Open circuit emit
receive channel: XXX” appears.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace TR64 board if the test result is FAIL.
C.1.25 Z0401 DSP FPGA and PHV ARM Interconnection
Test
 Top test items
PC Module and DSP FPGA Interconnection Test
 Test content
Test whether UART communication between DSP FPGA and PHV ARM works well.
Send the order through PHV serial port, and re-read the data via the port.
 Analysis to test failure
The drive goes wrong if the test result appears Error.
UART interconnection between DSP FPGA and SM ARM goes wrong if the test result
is FAIL.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace PHV board if the test result is FAIL.
C.1.26 Z0402 CW Mode Test
 Top test items
DSP FPGA and PHV ARM Interconnection Test
 Test content
Adjust the voltage of CW mode linearly, and set four voltage values. Read PHV1P
and PHV1N voltage value via PHV serial port.
 Analysis to test failure
The drive goes wrong if the test result appears Error.
The voltage value of CW mode does not meet the requirement if the test result is
FAIL.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace PHV board if the test result is FAIL.
