Setting
Selection Code Description
Search direction during
flying restart process C0140 = 0 Lenze setting
Only search in the direction of the applied setpoint
C0140 = 1 Only search against the direction of the applied
setpoint
C0140 = 2 Only search in positive direction of rotation
C0140 = 3 Only search in negative direction of rotation
C0140 = 4 Search at first in the direction of the applied setpoint
and then against the direction
C0140 = 5 Search at first against the direction and then in the
direction of the applied setpoint
C0140 = 6 Search at first in positive then in negative direction
of rotation
C0140 = 7 Search at first in negative then in positive direction
of rotation
Reference speed for
starting the search
process C0145 = 0 Flying restart circuit referenced to the maximum
speed (C0011).
Recommended when the motor speed is unknown
C0145 = 1 Lenze setting
Flying restart circuit referenced to the last current
motor speed
C0145 = 2 Speed setpoint, recommended when motor speed is
known
Value of current during
search process C0146 Influences the value of current during the search
process. Reduce the value in case of motors with low
centrifugal mass (speed already increases during
search process ).
Search speed C0147 Influences the search speed. A search process takes
approx. 1 ... 2 s. It may be required to reduce the
search speed to achieve a successful search process
(reduce value).
Activation
Selection Code Description
Start protection C0142 = 0 The flying restart circuit is inactive. protection
against unexpected start−up means that a restart
requires signal change for enabling the controller (e.
g. LOW−HIGH edge at X5/28).
Automatic start C0142 = 1 Lenze setting
Automatic start, flying restart circuit is inactive
Start after deactivating
the switch−on inhibit C0142 = 2 Flying restart circuit is started after resetting c
(mains connection, cancel of messages, (t > 0.5 s) or
TRIP RESET) and renewed controller enable (e. g.
LOW−HIGH edge at X5/28)
Starting without
protection against
unexpected start−up C0142 = 3 Flying restart circuit gets active immediately. No
renewed controller enable required (e. g. LOW−HIGH
edge at X5/28).
