Sinumerik Alarm 301717 Axis %1 drive %2 SSI transmission timeout
%1 = NC axis number
%2 = Drive number
The SSI transmission must be completed within an NC clock cycle. This is not possible with its current parameterization.
– Mode group not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
Either increase the clock cycle length of the NC or increase the SSI transmission rate (MD_1030 $MD_ACTUAL_VALUE_CONFIG_DIRECT.Bits 14 and 15). The following transmission rates are possible: 100 kHz, 500 kHz, 1 MHz and 2 MHz. Notice: It might be possible that the length of the encoder cable does not allow an increase in frequency!
Switch control OFF – ON.
