This alarm also occurs if 1PH2/4/6 motors are connected and no 611D performance control module is installed.
Replace the 611D control module.
Applies as from SW 5.4.
300744 Checksum error safe monitorings POWER ON
When powering up the control.
The power–up procedure is interrupted, the pulses remain disabled.
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.
Check all safety–related MDs and make any necessary corrections. Then execute a POWER ON. Carry out an
acceptance test.
Applies as from SW 5.4.
300745 Limit values for safe end position interchanged POWER ON
When powering up the control.
The power–up procedure is interrupted, the pulses remain disabled.
The data for the upper limit for SE monitoring contains a value less than that stored in the data for the lower limit.
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.
Applies as from SW 5.4.

When powering up the control.
The power–up procedure is interrupted, the pulses remain disabled.
The SBH/SG function is not enabled in MD 1301, although the SE/SN function is selected in this MD.
S 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.
Enable the SBH/SG function in MD 1301.
Applies as from SW 5.4.
300747 Monitoring cycle MD 1300 invalid POWER ON
When powering up the control.
The power–up procedure is interrupted, the pulses remain disabled.
