300743 Function not with this 611D control module
Scan
When powering up the control.
Effect
The power–up procedure is interrupted, the pulses remain disabled.
Explanation
The 611D performance control module is required for SINUMERIK Safety Integrated (see SINUMERIK Safety
Integrated documentation). This alarm is output if the hardware is not installed.
This alarm also occurs if 1PH2/4/6 motors are connected and no 611D performance control module is installed.
Remedy
Replace the 611D control module.
Note
Applies as from SW 5.4.
300744 Checksum error safe monitorings
Scan
When powering up the control.
Effect
The power–up procedure is interrupted, the pulses remain disabled.
Explanation
The actual checksum calculated by the drive and stored in MD 1398 via the safety–related MDs has a different
value to the reference checksum stored in MD 1399 on the last machine acceptance. The safety–related data
have been modified or an error has occurred.
Remedy
Check all safety–related MDs and make any necessary corrections. Then execute a POWER ON. Carry out an
acceptance test.
Note
Applies as from SW 5.4.
300745 Limit values for safe end position interchanged
Scan
When powering up the control.
Effect
The power–up procedure is interrupted, the pulses remain disabled.
Explanation
The data for the upper limit for SE monitoring contains a value less than that stored in the data for the lower limit.
Remedy
Check machine data
MD 1334 upper limit value for safe end position and
MD 1335 lower limit value for safe end position,
and change them such that the upper limit is greater than the lower limit. Then execute a POWER ON.
Note
Applies as from SW 5.4.
300746 No SBH/SG enable
Scan
When powering up the control.
Effect
The power–up procedure is interrupted, the pulses remain disabled.
Explanation
The SBH/SG function is not enabled in MD 1301, although the SE/SN function is selected in this MD.
S
Explanation
The SBH/SG function is not enabled in MD 1301, although the SE/SN function is selected in this MD.
S
Cam synchronization enabled without function SN active.
Remedy
Enable the SBH/SG function in MD 1301.
Note
Applies as from SW 5.4.
300747 Monitoring cycle MD 1300 invalid
Scan
When powering up the control.
Effect
The power–up procedure is interrupted, the pulses remain disabled.
Explanation
MD 1300 was not set to a multiple of the NC position control cycle.
Remedy
Set the monitoring cycle in MD 1300 to n * NC position control cycle, where n must be 1.
Note
Applies as from SW 5.4.
