Disabled
No function.
1
Enabled
Enable the frequency converter to catch and control a spinning
motor. When
P 5.6.3 Enable Flying Start
is enabled,
P 5.6.1 Start
Zero Speed Time
, and
P 5.6.2 Start Function
have no function.
2
Enabled Always
Enable flying start at every start command.
3
Enabled Reference Direction
Enable the frequency converter to catch and control a spinning
motor. The search is performed only in the reference direction.
4
Enabled Always Reference Direction
Enable flying start at every start command. The search is
performed only in the reference direction.
P 5.6.4 Start Speed [Hz]
Use this parameter to set the motor start speed. After the start signal the output speed leaps to the set value. This parameter can be used
for vertical movement applications (such as cone rotor). Set the start function in
P 5.6.2 Start Function
to
[3] Start Speed Clockwise
,
[4]
Horizontal Operation
, or
[5] VVC+ Clockwise
, and set a start delay time in
P 5.6.1 Start Zero Speed Time
.
Default value:

Parameter type:
Range (0.0–500.0)
Parameter
number:
175
Unit:
Hz
Data type:
uint16
Access type:
Read/Write
P 5.6.5 Start Current
Use this parameter to set the boost current for the motor. Some motors, for example cone-rotor motors, need extra current or starting
speed to disengage the rotor. To obtain this boost, set the required current in
P 5.6.5 Start Current
. Set the start speed with
P 5.6.4 Start
Speed [Hz]
. Set parameter
P 5.6.2 Start Function
to
[3] Start Speed Clockwise
or
[4] Horizontal Operation
, and set a start delay time in
P
5.6.1 Start Zero Speed Time
.
Default value:

Parameter type:
Range (0.00–1000.00)
Parameter
number:
176
Unit:
A
Data type:
uint32
Access type:
Read/Write
P 5.6.6 Breakaway Current Boost
Use this parameter to set the breakaway current boost. The frequency converter provides higher current than normal current levels to
enhance breakaway-torque capacity.
Default value:
0 [Off]
