Advice:
- The controls show the message numbers via
one or more rhythmically flashing LEDs.
The message number is found by adding
together the numbers next to the flashing
LEDs.
- During programming, all status messages and
other messages are suppressed. The messages
in programming mode are never ambiguous.
10.3 Fault messages
10. Messages
The message numbers serve two purposes:
1. They indicate why the controls were unable to carry out
the drive command given.
2. They indicate which components are faulty.
This facilitates better and faster service on site, and only
the control components identified as being faulty need be
replaced.
The controls remain in message mode until they switch to
operating mode or diagnostic mode.
