Parameter 1-74 Start Speed [RPM]
Table 126: Parameter 1-74 Start Speed [RPM]
1-74 Start Speed [RPM]
Default value: Size related
Conversion index: 67
Set a motor start speed. After the start signal, the output speed leaps to set value. Set the start function in parameter 1-72 Start
Function to [3] Start speed cw, [4] Horizontal operation, or [5] VVC+ /Flux clockwise, and set a start delay time in parameter 1-71 Start
Delay.
Parameter 1-75 Start Speed [Hz]
Table 127: Parameter 1-75 Start Speed [HZ]
1-75 Start Speed [HZ]
Default value: Size related
Conversion index: -1
This parameter can be used for hoist applications (cone rotor). Set a motor start speed. After the start signal, the output speed leaps
to the set value. Set the start function in parameter 1-72 Start Function to [3] Start speed cw, [4] Horizontal operation, or [5] VVC+/Flux
clockwise, and set a start delay time in parameter 1-71 Start Delay.
Parameter 1-76 Start Current
Table 128: Parameter 1-76 Start Current
1-76 Start Current
Default value: 0 A
Conversion index: -2
Some motors, for example cone rotor motors, need extra current/starting speed to disengage the rotor. To obtain this boost, set the
required current in parameter 1-76 Start Current. Set parameter 1-74 Start Speed [RPM]. Set parameter 1-72 Start Function to [3] Start
speed cw or [4] Horizontal operation, and set a start delay time in parameter 1-71 Start Delay. This parameter can be used for hoist
applications (cone rotor).
