7.3.1 Soft-stopping Mode (The P2 item is not set as"0",this stopping mode
is valid) When using this mode to stop the motor, the power
to
motor will be transferred from the by-pass contactor to the controlled
silicon of soft starter, and the output voltage of starter will be reduced
gradually so that the running speed of motor can be cut down smoothly
in case of the mechanical shock. The output ending voltage is the same
as the initial voltage. Soft-stopping mode can reduce or remove the surge
of the loading equipments such as the water pump. You can set the soft-
stopping limit-current value through the PF item to reduce the big-current
shock to the motor when stopping. This limit-current value is a percentage.
7.3.2 Free-stopping Mode (The P2 item is set as"0",this stopping mode
is valid) When using this mode to stop the motor, the Soft Starter will
cut off the connection to the by-pass contactor and forbid the controlled
silicon outputting voltage as soon as receiving the order of stopping.
The motor stops gradually because of its Inertia. Generally, if the soft-
stopping mode is not necessary, please choose the free-stopping mode
to length the service life of the soft starter. This mode will completely
forbids the instantaneous output, in case the instantaneous big-current
shock to the motor in special application state.
