p51583 CCP test turn-off command / CCP turn-off command
Description:
Setting to issue a turn-off command to the Converter Commutation Protector
(CCP) for test purposes.
Value:
0: No turn-off command
1: Issue in torque direction I
2: Issue in torque direction II
Notice:
After a turn-off command has been issued to the CCP, this parameter
automatically sets itself back to the value 0.
Note:
If the test command is issued during operation (i.e. in the operating state o0.1
or o0.2), then the turn-off operation of the SIMOREG CCP acts on the thyristor
bridge that is presently enabled. This is independent of issuing the turn-off
command in torque direction I or II.

Low byte: Command to the SIMOREG CCP
Bit0 = Fire turn-off thyristors
Bit1 = Line supply voltage (armature) is in the tolerance range
Bit2 = This SIMOREG CCP is connected to the parallel switching master
Bit3 = Main contactor CLOSE
Bit4 = Torque direction 1 active
Bit5 = Torque direction 2 active
Bit6 = always 1
Bit 7 = always 1
High byte: Diagnostics information about the monitoring of the blocking voltage-time
integral
The monitoring of the blocking voltage-time integral results in the SIMOREG CCP being
triggered (and A030 or F030 with fault value 1), if
bit 8 OR bit 9 = 1 AND ALL additional bits = 1 (i.e. the condition is fulfilled)
Bit 8 = Torque direction I AND EMF <= +5% (i.e. regenerative feedback)
Bit9 = Torque direction II AND EMF >= -5% (i.e. regenerative feedback)
Bit 10 = delay angle > 90° (i.e. regenerative feedback)
Bit 11 = no return pulse jump
Bit12 = Armature current flows
(The I = 0 signal has been present for a maximum of 0.6 ms)
Bit13 = The blocking voltage-time integral is too low
(< 50% of the theoretical value)
Bit14 = Decision-making criteria 1 is evaluated (see U580)
Bit15 = "No parallel operation" or "Parallel switching master"
(U800 = 0 OR U800 = 1 OR [U800 = 2 AND U806 > 10])
Note:
Bits 8 and 9 are always updated.
For all other a bits, the following applies: The bits after the first bit with the value zero
are invalid!
