Configuration
The coding of the jumpers enables different driving possibilities and different internal
functions in accordance to specific error messages.
In the following different definitions are explained which result from the specific possibili-
ties of coding!
a) „Switch on“ - „Switch off“
„Switch off“ means that the driving of the semiconductors and the power feedback will be
interrupted. A braking operation of the frequency inverter with power feedback is no long-
er possible.
„Switch-on“ is the activation of driving the semiconductors.
b) „Storage“
The unit is equipped with an error storage where special failures can be assigned to. Stored
error messages have to be confirmed by RESET or interruption of mains supply. "Storage"
always leads to a "switch-off" and to a collective-error-relay tripping.
c) Reset
After the failure is removed, a stored error has to be reset by pushing the RESET-button or
rather by switching-off and on again the main circuit voltage (3-ph.)
Danger!
A reset in case of too high DC-bus voltage during the braking operation is not recommended. If
it is done nevertheless, the power semiconductors are exposed to increased stress, which may
lead to accelerated aging.
d) „Phase failure“
The phase-failure-supervision monitors the mains supply in all 3 phases.
In case of a breakdown of one phase the unit stays still in function, but with reduced feed-
back power.
