1-72 Start Function
Option: Function:
start current in parameter 1-76 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.
[4] Horizontal
operation
Only possible with VVC
+
.
For obtaining the function
described in parameter 1-74 Start
Speed [RPM] and
parameter 1-76 Start Current during
the start delay time. The motor
rotates in the reference direction. If
the reference signal equals 0,
parameter 1-74 Start Speed [RPM] is
ignored and the output speed
equals 0. The output current
corresponds to the setting of the
start current in parameter 1-76 Start
Current.
[5] VVC+
clockwise
For the function described in
parameter 1-74 Start Speed [RPM]
only. The start current is calculated
automatically. This function uses
the start speed in the start delay
time only. Regardless of the value
set by the reference signal, the
output speed equals the setting of
the start speed in
parameter 1-74 Start Speed [RPM]. [3]
Start speed/current clockwise and [5]
VVC
+
clockwise are typically used in
hoisting applications. [4] Start
speed/current in reference direction is
particularly used in applications
with counterweight and horizontal
movement.
[7] VVC+ counter-
cw
1-73 Flying Start
Option: Function:
NOTICE
This parameter cannot be
adjusted while the motor is
running.
This function makes it possible to
catch a motor which is spinning
freely due to a mains dropout.
1-73 Flying Start
Option: Function:
[0] Disabled No function.
[1] Enabled Enables the frequency converter to
catch and control a spinning motor.
When parameter 1-73 Flying Start is
enabled, parameter 1-71 Start Delay
and parameter 1-72 Start Function
have no function. When
parameter 1-73 Flying Start is
enabled, parameter 1-58 Flying Start
Test Pulses Current and
parameter 1-59 Flying Start Test
Pulses Frequency are used for
specifying the conditions for the
ying start.

NOTICE
To obtain the best ying start performance, the
advanced motor data, parameter 1-30 Stator Resistance
(Rs) to parameter 1-35 Main Reactance (Xh), must be
correct.
1-74 Start Speed [RPM]
Range: Function:
Size
related*
[0 - 600
RPM]
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
+
clockwise, and
set a start delay time in
parameter 1-71 Start Delay.
1-75 Start Speed [Hz]
Range: Function:
Size
related*
[ 0 - 500.0
Hz]
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
+
clockwise, and
set a start delay time in
parameter 1-71 Start Delay.
