4.13 Main Menu - Data Readouts 2 - Group

18
Parameters in this group are array parameters, where up to
10 fault logs can be viewed. [0] is the most recent logged
data, and [9] the oldest. Error codes, values, and time
stamp can be viewed for all logged data

4.13.2 18-5* Ref. & Feedb.
18-50 Sensorless Readout [unit]
View the pressure or flow resulting from the sensorless
calculations. This value is not the value used for control. The
value will only be updated if sensorless data supports both flow
and pressure.

This parameter group is used for configuring the closed
loop PI Controller, that controls the output frequency of
the frequency converter.
4.14.1 20-0* Feedback
This parameter group is used to configure the feedback
signal for the closed loop PI control of the frequency
converter.

MG03N102 - Rev. 2013-12-02
Function:
This parameter allows a conversion function to
be applied to Feedback 1.
[0] Linear has no effect on the feedback.
[1] Square root is commonly used when a
pressure sensor is used to provide flow
feedback
( ).
flow ∝ pressure
l/s
Function:
[0 - 0 ] View information about the sensorless data.
Function:
to decrease when the feedback is greater than the
setpoint reference. This is common for pressure-
controlled supply fan and pump applications.
to increase when the feedback is greater than the
setpoint reference. This is common for
temperature-controlled cooling applications, such
as cooling towers.
Function:
[ 0 - Enter the motor speed to be attained as a
200.0 Hz] start signal for commencement of PI control.
Upon power up, the frequency converter
operates using speed open loop control.
When the Process PI start speed is reached,
the frequency converter changes to PI control.
