311716 Axis %1 drive %2 SSI measuring system without incremental signals not
possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: With the present module, it is not possible to use SSI encoders without incremental signals.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Use newer module.
Program Switch control OFF - ON.
Continuation:
311717 Axis %1 drive %2 SSI transmission timeout
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: SSI transmission must be able to finish within one position control cycle. This is not possible with its
current parameterization.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Either increase the position control cycle of the NC or increase the SSI transmission rate (MD 5011
$MD_ACTUAL_VALUE_CONFIG bits 14 and 15).
The following transmission rates are possible: 100 kHz, 500 kHz, 1 MHz and 2 MHz. Caution: It might
be possible that the length of the encoder cable does not allow an increase in frequency!
Program Switch control OFF - ON.
