How to Program
Function:
This function makes it possible to catch
spinning motor w hich is spinning freely
because of a mains drop-out.
Select Disable if this function is not required.
Select Enable if the freq u ency converter is to be
able to ’catch’ and control a spinning motor.
When par. 1-73 is enabled par. 1-71 and
1-72 have no function.
Flying start is active in VVC+ mode o nly.
NOTE
It is recommended not to u se this function
in hoisting applications.
1-74 Start Spee d [RPM]
Range:
0-600RPM
*
0RPM
Function:
Sets the desired motor start speed.
The motor output speed "leaps" to the set value. This
parameter can be used e.g. for hoist applications
(cone armature motors). Set the start function in
par. 1-72 to [3], [4] or [5], and set a start delay time
in par. 1-71. A reference signal must be present.
1-75 Start S peed [Hz]
Range:
0-500Hz
*
0Hz
Function:
Sets a start speed.
After the start signal, the output speed adjusts
to the set value. This parameter can be used
e.g. for hoist applications (cone rotor motors).
Setthestartfunctioninpar. 1-72to[3],[4]or
[5], and set a start delay time in p ar. 1-71. A
reference signal must be present.
1-76 Start Current
Range:
0.00 - par. 16-36 A
*
0.00A
Function:
Some motors, such as cone rotor motors, need extra
current/starting speed (boost) to disengage the
mechanical brake. For this purpose use par. 1-74
and par. 1-76. Set the required value to disengage
the me chanical brake. Set the start function in par.
1-72 to [3] or [4], and set a start delay time in par.
1-71. A reference signal mus t be p resent.
" 1-8* Stop Adjustments
1-80 Function at Stop

Pre-magnetizing [3]
Function:
Selects the drive function after a stop command
orafterthespeedisrampeddowntothe
settings in par. 1-81.
Select Coasting [0] to leave the motor in free
mode. A ctivate DC hold [1] D C holding current
(par. 2-00). Select Motor check [2] to check
if a motor has been connected.
Select Pre-magnetizing [3] to build up a magnetic
field w hile the motor is stopped. The motor can
now produce a quick torque build-up at start.
1-81 Min Speed for Function at Stop [RPM]
Range:
0-300RPM
*
0RPM
Function:
Sets the speed at which to activate Function
at stop (par. 1-8 0).

Function:
Set the frequency at which the function to activate
function at stop is selected in par. 1-80.
