Selection number Selection name Selection description
0 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: Size Related 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: Size Related 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] Parameter type: Selection
Parameter
number:
422 Unit: –
Data type: enum Access type: Read/Write
The following are the selections for the parameter.
