P 5.6.2 Start Function
Use this parameter to select the start function during start delay, in case a non-zero value is set in P 5.6.1 Start Zero Speed Time.
Default value:
2 [Coast/delay time]
Parameter
172
number:
Data type:
enum
The following are the selections for the parameter.
Selection number Selection name
0 DC Hold/delay time
1 DC-Brake/delay time
2 Coast/delay time
3 Start speed clockwise
4 Horizontal operation
5 VVC+ clockwise
P 5.6.3 Enable Flying Start
Use this parameter to control the flying start function. This function makes it possible to catch a motor which is spinning freely due to a
mains dropout.
Default value:
0 [Disabled]

Selection description
Energize motor with a DC hold current (P 5.7.6 DC Hold Current
%) during the start delay time.
Energize motor with a DC break current (P 5.7.4 DC Brake Current
%) during the start delay time.
Motor coasted during the start delay time (inverter off ).
Only possible with VVC+. Regardless of the value applied by
the reference signal, the output speed applies the setting of the
start speed in P 5.6.4 Start Speed [Hz] and the output current
corresponds to the setting of the start current in P 5.6.5 Start
Current. This function is typically used in hoisting applications
without counterweight and especially in applications with a
cone-motor, where the start is clockwise, followed by rotation in
the reference direction.
Only possible with VVC+. For obtaining the function described
in P 5.6.4 Start Speed [Hz] and P 5.6.5 Start Current during the
start delay time. The motor rotates in the reference direction. If
the reference signal equals 0, P 5.6.4 Start Speed [Hz] is ignored
and the output speed equals 0. The output current corresponds
to the setting of the start current in P 5.6.5 Start Current.
The start current is calculated automatically. This function uses
the start speed in the start delay time only.
