Reset (RST)
A fault message can be acknowledged by activating and
subsequently deactivating (i.e. resetting) the digital input
configured as RST.
X
Program one of the digital inputs 1 to 5 as RST by entering the
value 18 under the corresponding PNU (C001 to C005).
By default, RS is assigned to digital input 1.
Under PNU C103, you can select how the frequency inverter
responds after the reset signal drops out. You can specify whether
the frequency inverter synchronizes to the frequency set under
PNU b007 or starts at 0 Hz.

Here, set a time which is to expire before an automatic
restart is initiated after a fault signal. This time can also be
used in conjunction with the FRS function. During the delay,

Warning!
If a reset is carried out after a fault, the motor will start
immediately if a start signal is applied simultaneously. To
avoid the risk of serious or fatal injury to personnel, you
must ensure that the start signal is not present before
acknowledging an error message with a reset .
h
When a fault has occurred, the OFF key on the keypad
acts as a RESET key, and can be used instead of the RST
input to reset the fault.
h
If the RST input is active for more than four seconds, it can
cause a false trip.
h
The RST input is always a make (NO) contact and cannot
be programmed as a break (NC) contact.
h
Alternatively, you can acknowledge a fault message by
briefly switching the supply voltage off and on again.
h
If a reset is initiated during operation, the motor coasts to
a stop.
