41, 42:
MI, MII Alpha-W pulse with second pulse in the old torque direction.
Cause: additional Alpha-W pulses according to p50179.
51, 52:
MI, MII Alpha-W pulse without second pulse in the old torque direction.
Cause: additional Alpha-W pulses according to p50161.
60, 61, 62:
M0, MI, MII torque direction according to p51840 (simulation operation).
71: MI the command "simultaneously fire all thyristors" (according to p50176) was performed.
81: MI the torque direction specified by the thyristor check was realized.
82: MII the torque direction specified by the thyristor check was realized.
95, 96, 97:
M0, MI, MII the torque direction of the parallel switching master was realized.
Note: This parameter is only for internal SIEMENS troubleshooting.
Description: Displays the number of zero current signals of the armature current.
For scan values below the threshold I = 0, the counter is incremented.
The counter is reset in the following cases:
- firing pulse.
- scan value above the threshold for I = 0.
Note: This parameter is only for internal SIEMENS troubleshooting.
The scan values are every 62.5 µs.
The threshold for I = 0 is 1 % of the rated unit current.
Description: Displays the thyristor code.
Bit 0 = 1: Thyristor 1 was fired
...
Bit 5 = 1: Thyristor 6 was fired
Bit 6 = 1: thyristors were fired for torque direction 1
Bit 7 = 1: thyristors were fired for torque direction 2
Note: This parameter is only for internal SIEMENS troubleshooting.
