Axis %1 drive %2 multiturn SSI motor measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The configuration of a linear SSI motor measuring system is incorrect: A linear measuring
system cannot have any multiturn information.
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Set MD_1021 $MD_ENC_ABS_TURNS_MOTOR (resolution number revolution) to 0.
Program Con- Switch control OFF - ON.
tinuation:
301713
Axis %1 drive %2 resolution SSI direct measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Configuration of the direct measuring system is faulty for SSI encoder: MD_1032
$MD_ENC_ABS_RESOL_DIRECT must not be 0.
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Set MD_1032 $MD_ENC_ABS_RESOL_DIRECT to the correct value:
• Rotary encoder: Singleturn resolution (increments per revolution).
• Linear encoder: Resolution of an increment (in nanometers).
Program Con- Switch control OFF - ON.
tinuation:
301714
Axis %1 drive %2 transmission length SSI direct measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Configuration of the direct measuring system is faulty for SSI encoder: MD_1041
$MD_NO_TRANSMISSION_BITS_DM (SSI transmission length) is smaller than the num-
ber of all parameterized bits in MD_1031 $MD_ENC_ABS_TURNS_DIRECT (multiturn),
MD_1032 $MD_ENC_ABS_RESOL_DIRECT (singleturn) and MD_1037
$MD_ENC_CONFIG_DIRECT Bit 14 (alarm bit) and MD_1037
$MD_ENC_CONFIG_DIRECT Bit 12 (parity bit).
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Set parameters correctly for all associated machine data:
• MD_1041 $MD_NO_TRANSMISSION_BITS_DM (SSI transmission length): number of
bits in an SSI protocol, including all bits such as alarm bit and parity bit.
