Description
Defines the time for the pump-motor to decelerate
from the speed set in parameter
down to 0.
Note: If parameter 75.23 Ramp switch speed
greater than 0, then this parameter ramp time setting
is used while speed reference is in lower speed region.
Deceleration time 2 in seconds.
Defines the source for Acceleration assistance enable
signal.
For further information, see section Acceleration
assistance .
Acceleration assistance is inactive.
Acceleration assistance is active.

Defines the speed limit at which acceleration assistance
is automatically disabled.
The assistance current boost is produced only once. If
the speed is below the value set in the parameter, then
no repeated current boost is applied.
Acceleration assistance speed limit.
Defines motor current reference used when the
acceleration assistance routine is active. The base value
to calculate the acceleration assistance current is
parameter 99.6 Motor nominal
Acceleration assistance current.
Defines the source for Kick-start enable signal.
Note: If used with step-up transformer, Kick-start
function provides pre-magnetization for the motor to
increase starting torque. Else, it can be used to improve
the motor performance during start.
