r7251[0...4]

Par_circuit power unit rated current / PU PI_rated

B_INF (Parallel), Can be changed: -
VECTOR_G (Parallel)
Data type: FloatingPoint32
P-Group: Converter
Not for motor type: -
Min
- [Arms]
Description: Displays the rated current of the individual power units connected in parallel for various load duty cycles.
The sum of the rated currents of all power units connected in parallel is displayed in r0207.
Index: [0] = Rated value
[1] = Load duty cycle with low overload
[2] = Load duty cycle with high overload
[3] = S1 cont duty cyc
[4] = S6 load duty cycle
Dependency: Refer to: p0205
r7252[0...4]

Par_circuit maximum power unit current / PU I_max

B_INF (Parallel), Can be changed: -
VECTOR_G (Parallel)
Data type: FloatingPoint32
P-Group: Converter
Not for motor type: -
Min
- [Arms]
Description: Displays the maximum output current of the individual power units connected in parallel.
The sum of the maximum currents of all power units connected in parallel is displayed in r0209.
Index: [0] = Rated value
[1] = Load duty cycle with low overload
[2] = Load duty cycle with high overload
[3] = S1 cont duty cyc
[4] = S6 load duty cycle
Dependency: Refer to: p0205
r7740[0...n]

IGBT power cycling counter valve 1 / IGBT load count 1

B_INF, VECTOR_G Can be changed: -
Data type: Unsigned16
P-Group: -
Not for motor type: -
Min
-
Description: Displays the status of power cycling counter for valve 1.
For repairs, this parameter serves as internal documentation for service personnel.
The counter state corresponds to the valve wear. A maximum of 650% of the specified service life is displayed.
10000 corresponds to the nominal service life (100%). When this value is reached, the IGBT is theoretically at the
end of its service life and must be replaced.
Dependency: Refer to: p7786
Notice: After a valve has been replaced, the corresponding power cycling counter must be reset.
Note: The IGBT power cycling counter can only be set to 0.
Procedure when replacing valve 1:
1. Switch off the system and replace valve 1.
2. Switch on the system and acknowledge that valve 1 has been replaced (p7786.1 = 1).
--> the power cycling counter of valve 1 is reset (r7740 = 0).
3. Carry out a POWER ON (power off/on).
--> as a consequence p7786.1 is automatically set to 0.
