Deceleration Ramp Type [338]
Sets the ramp type of all deceleration parameters in a
parameter set Fig. 102.
Communication information
Fig. 102 Shape of deceleration ramp
Start Mode [339]
Sets the way of starting the motor when a run command is
given.
Communication information
Spinstart [33A]
The spinstart will smoothly start a motor which is already
rotating by catching the motor at the actual speed and
control it to the desired speed. If in an application, such as
an exhausting fan, the motor shaft is already rotating due to
external conditions, a smooth start of the application is
required to prevent excessive wear. With the spinstart=On,
the actual control of the motor is delayed due to detecting
the actual speed and rotation direction, which depend on
motor size, running conditions of the motor before the
Spinstart, inertia of the application, etc. Depending on the
motor electrical time constant and the size of the motor, it
can take maximum a couple of minutes before the motor is
caught.

339 Start Mode
Default: Normal DC
Fast 0
The motor shaft starts rotating
immediately once the Run command is
given. The motor flux increases gradually.
Normal
DC
1
After a Run command the motor will be
magnetised first and the stator resistance
is measured
. Depending on the motor
time constant and the size of the motor it
can take up to 1.3 s before the motor
shaft starts to rotate.
This will provide
better control of the motor when starting.

33A Spinstart
Default: Off
Off 0
No spinstart. If the motor is already running
the AC drive can trip or will start with high
current.
On 1
Spinstart will allow the start of a running
motor without tripping or high inrush
currents. If encoder feedback is used, both
encoder speed and current signals are used
to perform spinstart function.
Encoder 2
Only encoder speed used for detecting
rotating machine, i.e. no rotating machine
detection via initial motor current.
Note: Only active if encoder is present. If no
Encoder, functionality is equal to selection
Off.
