Functional Description 93
Deceleration Ramp Type [338]
Sets the ramp type of all deceleration parameters in a
parameter set Fig. 79.
Communication information

Start Mode [339]
Sets the way of starting the motor when a run com-
mand 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 appli-
cation, 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.
Communication information
Stop Mode [33B]
When the VSD is stopped, different methods to come to
a standstill can be selected in order to optimize the
stop and prevent unnecessary wear, like water ham-
mer. Stop Mode sets the way of stopping the motor
when a Stop command is given
.

No spinstart. If the motor is already running
the VSD can trip or will start with high current.

Spinstart will allow the start of a running
motor without tripping or high inrush currents.

Decel 0
The motor decelerates to 0 rpm according
to the set deceleration time.
Coast 1 The motor freewheels naturally to 0 rpm.
