6-345
Remedy Enable the function SBH/SG via MD 1301: $MD_SAFE_FUNCTION_ENABLE
(enable safe functions)
Program continuation Power-down the control and power-up again.
300747 Axis %1, drive %2 Invalid monitoring cycle clock for MD 1300
Parameter %1 = NC axis number
%2 = drive number
Explanation MD 1300: $MD_SAFETY_CYCLE_TIME (monitoring clock cycle) was not set
as a multiple of the NC position controller clock cycle.
Interrogation: When the control runs-up.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
NC stop for alarm
Alarm display
Interface signals are set
Remedy Using MD 1300, set the monitoring cycle to n * NC position control cycle. Note
that n must be >= 1.
Program continuation Power-down the control and power-up again.
300748 Axis %1, drive %2 Monitoring cycle not identical for both axes
Parameter %1 = NC axis number
%2 = drive number
Explanation The monitoring clock cycle in MD 1300: $MD_SAFETY_CYCLE_TIME
(monitoring time) for the two axes of a 2-axis module has not been set to the
same value.
Interrogation: When the control runs-up.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
NC stop for alarm
Alarm display
Interface signals are set
Remedy Set MD 1300: $MD_SAFETY_CYCLE_TIME (monitoring cycle) the same on all
drives of the module.
Program continuation Power-down the control and power-up again.
300749 Axis %1, drive %2 conversion factor between motor and load too
large
Parameter %1 = NC axis number
%2 = drive number
Explanation The factor to convert from the motor system [increments] to the load system
[µm/mdeg] is larger than 1 or the factor which converts the load system to the
motor system is larger than 65535.
Conditions:
The condition for the factor to convert from the load system to motor system is:
µm_to_incr <= 65535
The condition for the factor to convert from the motor system to load system is:
inkr_to_µm <= 1 with µm_to_inkr = 1 / inkr_to_µm
Formula for rotary axis:
The following applies for rotary motor encoder and rotary axis:
inkr_to_µm(n) = (MD1321 SAFE_ ENC_ GEAR_ DENOM(n) / (MD1322 SAFE_
ENC_NUMERA(n)) * inkr_to_µm_rot_rund
with n = 0 ... 7 (gear stage) and
inkr_to_µm_rot_rund = (360000 / 8192) * (1 / MD1318 SAFE_ENC_RESOL)
