Armature current zero current signal / Ia I=0 signal

DC_CTRL Can be changed: -
Data type: Unsigned8
P-Group: -
Not for motor type: -
Min
-
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.
