3
F-23 Start Speed [Hz]
Range:
0 Hz* [0.0 - 500.0 Hz]
F-24 Holding Time
Range:
0.0 s* [0.0 - 10.0 s]
F-25 Start Function
Option:
[0] DC Hold/delay time
[1] DC Brake/delay time
[2] * Coast/delay time
[3] Start speed cw
[4] Horizontal operation
[5] Adv. Vector Control/Flux Clockwise
[6] Hoist Mech. Brake Rel
F-26 Motor Noise (Carrier Freq)
Select the inverter switching frequency. Changing the switching frequency can help to reduce acoustic noise from the motor. Default depend on power size.
Option:
[0] 1.0 kHz
42
Function:
Set a motor start speed. After the start signal, the output speed leaps to set value. Set the start function
in par. F-25 Start Function to [3], [4] or [5], and set a start delay time in par. F-24 Holding Time.
Function:
Set a motor start speed. After the start signal, the output speed leaps to set value. Set the start function
in par. F-25 Start Function to [3], [4] or [5], and set a start delay time in par. F-24 Holding Time.
Function:
This parameter refers to the start function selected in par. F-25 Start Function.
Enter the time delay required before commencing acceleration.
Function:
Select the start function during start delay. This parameter is linked to par. F-24 Holding Time.
Energizes motor with a DC holding current (par. B-00 DC Hold Current) during the start delay time.
Energizes motor with a DC braking current (par. B-01 DC Brake Current) during the start delay time.
Releases shaft coasted converter during the start delay time (inverter off).
Only possible with .
Connect the function described in par. F-22 Start Speed [RPM] and par. F-29 Start Current in the start delay
time.
Regardless of the value applied by the reference signal, the output speed applies the setting of the start
speed in par. F-22 Start Speed [RPM] or par. F-23 Start Speed [Hz] and the output current corresponds to
the setting of the start current in par. F-29 Start Current. This function is typically used in hoisting appli-
cations without counterweight and especially in applications with a Cone-motor, where the start is
clockwise, followed by rotation in the reference direction.
Only possible with .
For obtaining the function described in par. F-22 Start Speed [RPM] and par. F-29 Start Current during the
start delay time. The motor rotates in the reference direction. If the reference signal equals zero (0), par.
F-22 Start Speed [RPM] is ignored and the output speed equals zero (0). The output current corresponds
to the setting of the start current in par. F-29 Start Current.
for the function described in par. F-22 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 par. F-22 Start Speed [RPM].Start speed/
current clockwise [3] and Advanced Vector Control/Flux clockwise [5] are typically used in hoisting appli-
cations. Start speed/current in reference direction [4] is particularly used in applications with counter-
weight and horizontal movement.
For utilizing mechanical brake control functions, par. B-24 Stop Delay to par. B-28 Gain Boost Factor. This
parameter is only active when par. H-41 Motor Control Principle is set to [3] Flux w/ motor feedback.
