DGN 355 Communication alarm ignore counter (separate type)
DGN 356 Link processing counter (built-in type)
DGN 357 Link processing counter (separate type)
The number of times a communication error occurred during serial
communication with the detector is indicated.
Data transmitted during communication is guaranteed unless another
alarm occurs. However, if the counter value indicated in this
diagnosis information increases in a short period, there is a high
probability that serial communication is disturbed by noise. So, take
sufficient measures to prevent noise.

MOTOR αi series.
DGN 358 V ready-off information
This information is provided to analyze the cause of the V
ready-off alarm (servo alarm SV0401).
Convert the indicated value to a binary representation, and check bits
5 to 14 of the binary representation.
When amplifier excitation is turned on, these bits are set to 1
sequentially from the lowest bit, which is bit 5. If the amplifier is
activated normally, bits 5 to 14 are all set to 1.
Therefore, check the bits sequentially from the lowest bit to find the
first bit that is set to 0. This bit indicates that the corresponding
processing could not be completed and so the V ready-off alarm was
caused.
