Parameter 1-74 Start Speed [RPM]
Table 125: Parameter 1-74 Start Speed [RPM]
1-74 Start Speed [RPM]
Default value: Size related
Parameter type: Range, 0 - 600 RPM
Setup: All setups
Conversion index: 67
Data type: Uint16
Change during operation: True
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 126: Parameter 1-75 Start Speed [HZ]
1-75 Start Speed [HZ]
Default value: Size related
Parameter type: Range, 0 - 500.0 Hz
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
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 127: Parameter 1-76 Start Current
1-76 Start Current
Default value: 0 A
Parameter type: Range, 0 - par. 1-24 A
Setup: All setups
Conversion index: -2
Data type: Uint32
Change during operation: True
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).
5.2.9 1-8* Stop Adjustments
Parameter 1-80 Function at Stop
Table 128: Parameter 1-80 Function at Stop
1-80 Function at Stop
Default value: [0] Coast
Parameter type: Option
Setup: All setups
Conversion index: –
Data type: Uint8
Change during operation: True
Select the drive function after a stop command or after the speed is ramped down to the settings in
parameter 1-81 Min Speed for
Function at Stop [RPM]
.
