- These adjustment parameters can be modified with the speed controller stopped or
running. Ensure that changes made during operation do not present any danger.
Changes should preferably be made with the speed controller stopped.
Code Assignment
- - - - L L L L F F F F r r r r Speed reference via the display module.
This parameter appears with the remote display module option if control of
the speed controller via the display module is enabled : LCC parameter in
I-O- menu.
- - - - r r r r P P P P I I I I Internal PI reference
This parameter appears if analog input AIC/AI2 is assigned to the internal PI
function (AIC = PII).
The adjustment range of rPI is a percentage of AI max. (internal value of the
frequency reference).
AI max. depends on the voltage applied at AI2 or on the input current in AIC
and the CrL and CrH parameter settings in the I/O menu (see page 81).
To define rPI:
(AIC x FbS) - CrL
rPI = 100
Example: process control with 10 mA of feedback on input AIC configured
as 4 mA - 20 mA.
10 - 4
rPI = 100

- - - - A A A A C C C C C C C C Acceleration and deceleration ramp times
- - - - d d d d E E E E C C C C Defined to range from 0 to nominal frequency bFr
Ensure that the value of DEC is not too low in relation to the load to be
stopped.
The parameters in shaded boxes appear if the corresponding functions have been configured
in the drC- or I-O- menus.
