the internal parameter set to
the external memory.
It has loaded the internal pa-
rameter set to its RAM.
• External parameter
memory is not connected.
• Data transmission error.
• Internal parameter set too large
to be copied to the external me-
mory (memory is full).
• The external parameter memo-
ry is defective.
• Ensure that the external pa-
rameter memory is connected
correctly (free wiring: check
wire assignment).
• Repeat the startup procedure.
