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.

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.

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.
