SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
Axis %1, drive %2 message frame length invalid for SSI motor measuring
system
%1 = NC axis number
%2 = drive number
The motor measuring system is incorrectly configured for an SSI encoder.
Mode group not ready.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
Alarm display.
Interface signals are set.
Check the following MD and correct if necessary
MD 5028
MD 5021 (Multi-turn): Number of resolvable revolutions
MD 5022 (Single-turn): Number of increments per revolution
MD 5027 Bit 12: Parity bit
MD 5027 Bit 14 Alarm bit
Example:
SSI encoder with 25-bit long message frame, 12 bits multi-turn, 12 bits single-
turn, 1 alarm bit, no parity bit:
MD 5028 = 25
MD 5021 = 4096
MD 5028= 4096
MD 5027 bit 12 = 0
MD 5027 bit 14 = 1
Switch control system OFF and ON again.
Axis %1, drive %2 Invalid multi-turn SSI motor measuring system
%1 = NC axis number
%2 = drive number
The motor measuring system is incorrectly configured for a linear SSI motor
measuring system. A linear measuring system cannot have any multiturn infor-
mation.
Mode group not ready.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
Alarm display.
Interface signals are set.
Set MD 5021 to 0.
