"Undervoltage in the DC link"
♦ The DC link voltage has fallen below the permissible limit value.
From drive status (°011) fault message (F008) "DC link
undervoltage" is additionally output.
Refer to the Section "Fault- and alarm messages"
The main contactor (AC unit)/precharging contactor (DC unit) (option) is
operated.
♦ The main contactor/precharging contactor (option) can be driven
with the appropriate wiring and parameterization.
Ramp-function generator active
♦ The ramp-function generator output (r480 / KK0073) is not equal to
the ramp-function generator input (r460 / KK0072).
A hysteresis, which can be parameterized (P476 as %, referred to
the rated system frequency P352), can only be taken into account
for an analog setpoint input.
♦ When the "synchronizing" function is selected, alarm A069 is
initiated, as long as the ramp-function generator is active in the
setpoint channel of the synchronizing converter.
The synchronizing operation is not started as long as the ramp-
function generator is active.
Clockwise rotating field
♦ The frequency setpoint for the closed-loop control (speed/frequency
setpoint, r482 / KK0075) is greater than or equal to 0.
Counter-clockwise rotating field
♦ The frequency setpoint for the closed-loop control (speed/frequency
setpoint, r482 / KK0075) is less than 0.
The kinetic buffering (KIP) function or flexible response (FLN) is active.
♦ KIP:
A brief power failure is bypassed using the kinetic energy of
the connected load.
♦ FLN:
The converter can be operated up to a minimum DC link
voltage of 50% of the rated value.
