Cause Of The Torque Direction / Cause M_Dir - Siemens SINAMICS DCM List Manual

4: The firing angle received from the parallel switching master was issued.
5: The firing angle received from the parallel switching master was no longer able to be realized, as this point in time
has already been passed.
6: For a 12-pulse series circuit, a firing pulse delayed by 30 ° was output.
7:The firing angle specified by the thyristor check function was realized.
8:The master firing angle specified by the sequential phase control was realized.
9:The slave firing angle specified by the sequential phase control was realized.
1x:
firing angle = next possible point in time: firing angle update was not able to be realized.
2x:
firing angle = next possible point in time: new firing angle was not able to be realized.
3x:
firing angle = next possible point in time: calculated firing angle was not able to be realized.
Note: This parameter is only for internal SIEMENS troubleshooting.

Description: Displays the cause of the torque direction.
0: M0 no torque direction, as not in the operating mode.
1: M0 no torque direction as a firing angle > 165 ° was specified.
2: M0 no torque direction as the wait time according to p50160 is running.
3: M0 no torque direction as the signal selected with p50165 does not permit the required torque direction.
4: M0 no torque direction as the I=0 signal was 125 µs long but however was present for less than 625 µs. The
torque-free interval is extended.
5: M0 no torque direction as the thyristor blocking voltage monitoring signals "thyristor conductive". The torque-free
interval is extended.
6: M0 no torque direction as the immediate pulse inhibit according to p50177 has been selected.
7: M0 no torque direction, as an emergency stop is present.
8: M0 no torque direction, as the line supply is not OK.
9: M0 no torque direction, as a valid firing instant was not found (for example, this can occur in the slave connected in
parallel if the master is lost).
10, 11, 12:
M0, MI, MII torque direction = r52106.
15: M0 no torque direction as the selected thyristor pair is inhibited during the thyristor check.
16: M0 no torque direction, as the slave connected in parallel is not in the operating state.
17: M0 no torque direction, as an immediate pulse inhibit was executed, because either an emergency stop is
present or the CCP was triggered.
21, 22:
MI, MII Alpha-W pulse with second pulse in the old torque direction.
Cause: Ia was still not 625 µs long = 0.
23, 24:
MI, MII Alpha-W pulse with second pulse in the old torque direction.
Cause: thyristor blocking voltage monitoring signals "Thyristor conductive"
31, 32:
MI, MII Alpha-W pulse without second pulse in the old torque direction.
Cause: Ia was still not 625 µs long = 0.
33, 34:
MI, MII Alpha-W pulse without second pulse in the old torque direction.
Cause: thyristor blocking voltage monitoring signals "Thyristor conductive"
