Parameter P2253 allows the user to select the source of the PI setpoint.  Normally a digital PI setpoint is selected using either a Fixed PI
setpoint or an active setpoint.  The most common settings are as follows:

755

=

Analog input 1

2224

=

Fixed PI setpoint (see P2201 to P2207)

2250

=

Active PI setpoint  (see P2240)

Sets the ramp up time for the PI setpoint.

time (s)

Ramp up time

(P2257)

Setting the ramp – up time too short may cause the inverter to trip, on overcurrent for
example.

If PI control is enabled, the normal ramp-up time (P1120) is disabled.
The PI ramp time is only effective on the PI setpoint and only active when the PI setpoint is
changed, or when a RUN command is given (when the PI uses this ramp to reach its value
from 0%).
