Voltage setpoint for the upper response threshold of the SIMOREG
CCP chopper
[from SW 2.2 and higher]
The set voltage value defines the upper response threshold of the voltage
limiter implemented in the SIMOREG CCP. Within the scope of the turn-off
operation of the CCP, this limits the counter-voltage that occurs - which is
also necessary - when the armature current is reduced to a value that is not
dangerous for the basic unit and the associated SIMOREG CCP. The
required setting value depends on the blocking voltage strength of the
power semiconductors used in the basic converter (SIMOREG DC-
MASTER) and in the SIMOREG CCP and is therefore dependent on the
Unit MLFB.
The following table should be used to correctly set this parameter.
As a result of the unit MLFB for the basic converter and SIMOREG CCP,
two setting values are obtained from which the lower of the two should be
set at U577.
Example:
Basic converter MLFB: 6RA7085-6DV62-0 (r070=9)
⇒
U577=1300 V
SIMOREG CCP MLFB: 6RA7085-6FC00-0 (n570=250)
⇒
U577=1100 V
therefore the following setting is obtained: U577=1100 V
Table to determine the setting value for U577:
Ind: None
FS=1600
Type: O2
P052 = 3
P051 = 40
