30.0 s / real32 Defines the time for the pump-motor to decelerate
from the speed set in parameter
46.2 Frequency scaling
down to 0.
Note: If parameter 75.23 Ramp switch speed is set to
greater than 0, then this parameter ramp time setting
is used while speed reference is in lower speed region.
Deceleration time 2 75.25
1 = 1 s / 10 = 1 s Deceleration time 2 in seconds. 0.0 ... 1800.0 s
ESP CW bit 4 / unit32 Defines the source for Acceleration assistance enable
signal.

20.0% / real32 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 75.42
10 = 1% / 10 = 1% Acceleration assistance speed limit. 0.0 ... 100.0%
100.0% / real32 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 current .
Acceleration
assistance current 75.46
10 = 1% / 10 = 1% Acceleration assistance current. 0.0 ... 300.0%
ESP CW bit 5 / unit32 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.
For further information, see section Kick-start.
