SINUMERIK 840D/840Di/810D Diagnostics Guide (DA), 10.04 Edition
• Example:
• SSI encoder with 25 bits transmission length, 12 bits multiturn, 12 bits singleturn, one
alarm bit:
• $MD_NO_TRANSMISSION_BITS_DM = 25
• $MD_ENC_ABS_TURNS_DIRECT = 4096
• $MD_ENC_ABS_RESOL_DIRECT = 4096
• $MD_ENC_CONFIG_DIRECT.Bit 14 = 1
• $MD_ENC_CONFIG_DIRECT.Bit 12 = 0
Switch control OFF - ON.
Axis %1 drive %2 multiturn SSI direct measuring system invalid
%1 = NC axis number
%2 = Drive number
Configuration faulty for a linear and direct measuring system with SSI: A linear measuring
system cannot have any multiturn information.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Set MD_1031 $MD_ENC_ABS_TURNS_DIRECT (resolution number revolution) to 0.
Switch control OFF - ON.
Axis %1 drive %2 SSI direct measuring system without incremental signals not
possible
%1 = NC axis number
%2 = Drive number
With the present module, it is not possible to use SSI encoders without incremental sig-
nals.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Use newer module.
Switch control OFF - ON.
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.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
