Converter voltage-frequency test
This menu option allows you to run the converter voltage-frequency test (or VFC) of the CPU-C1C.X board. When you access this
option, the display shows digits AAA BBB, as shown in figures F2.12 and F2.13.
Figure F2.12: VFC Test Message
Figure F2.13: VFC value message
Value AAA refers to pick-up VFC A, whereas value BBB refers to pick-up VFC B. The values displayed must be stable (operators should
not touch or knock the machine) and must range within the tolerance levels indicated in table T10.2. When the machine is touched
or knocked both VFC channels will vary and should stabilize once the mechanical disturbance is over.
To exit the voltage-frequency converter test program, press [F+P9] .
