I2t Control Word
Control word for the i
2
t power section
0 Response of the i
2
t monitor for the power section (i.e. 100% of
the i
2
t value has been reached) results in an automatic
reduction of the limit for the current setpoint to the rated DC
current (in infeed direction or at 92% of the rated direct current
in regenerative feedback direction) until the absolute value of
the current setpoint has dropped below the rated DC current
before its limit (or 92% of that in regenerative feedback
direction) and the calculated equivalent junction temperature
rise is again below the unit-specific response threshold. The
current setpoint limit is then raised again.
1 Response of the i
2
t monitor for the power section (i.e. 100% of
the i
2
t value has been reached) results in fault F022 and
disconnection.

P793 Line Voltage Delay
Stabilizing time for the line voltage
If the "Switch-on" command is given, the unit waits in status
o
010 for
voltage to be applied to the power section. The line voltage is not assumed
to be applied to the power terminals until amplitude, frequency and phase
symmetry lie within the permissible tolerance range for longer than the time
set with this parameter. The parameter applies to both the rectifier and
regenerative power terminals.
