P-32
t-DCBrake@Stop
0.0 s
25.0 s
Duration of DC braking at Stop and before Start.
Setting “0” disables DC braking. The braking level
is set using P-68.
0.0 s
DCBrake
0
2
Sets the instances when DC braking is enabled.
0: DC braking on Stop
1: DC braking before Start
2 : DC braking before Start and on Stop
0
P-33
Spin Start Enable
0
2
Spin Start Enable
Enables spin start, where the drive starts from the
detected motor speed. A short start delay is
possible if the rotor is stationary.
Recommended for applications where the motor
spins when applying the FWD/REV signal to the
drive (high inertia loads, fans ...)
0: Spin start disabled
1: Spin start enabled
2 : Spin start enabled in the event of a fault,
network outage, or coast to stop (P-05 = 1)
Note:
The settings for P-33 will be adjusted if parameter
P-13 is changed. (P-33 = 0 if P-13 = 0 or 1, P-33 = 2
if P-13 = 2)
0
P-34
Brake Chopper
0
4
Enable Brake Chopper
Enables the brake chopper for size FS2. Software
protection can be selected for brake resistors with
a 200 W nominal power rating.
0: Brake chopper not enabled
1: Brake chopper enabled with software protection
2 : Brake chopper enabled without software
protection
3: Brake chopper enabled during speed setpoint
change only (with software protection)
4: Brake chopper enabled during speed setpoint
change only (without software protection)
Note:
This parameter can only be set to a value > 0 on
devices of size FS2. Devices with frame size FS1 do
not feature an internal braking chopper

AI1 Gain

2000.00%
Scaling of the Analog Input 1
Output value = Input value * Scaling.
Example: P-16 = 0 - 10 V, P-35 = 200 %:
at 5 V the motor would run at max. speed (P-01)
(5 V x 200 % = 10 V)
In slave mode (P-12 = 14) the slave speed is scaled
with P-35.
