ero electronic LFS - Operative Parameters: Servomotor and Gradient; Servomotor Limits and Gradient Settings

26
GB
SNHL Servomotor high limit
This parameter is available only when
P5 = Sm.CL
Range from SnLL to 100 (in % of the
feedback potentiometer span).
CY1 Output 1 cycle time
This parameter is available only if P5 is
equal to "REU" or "DIR".
Range:From 1 to 200 s.
CY3 Output 3 cycle time
This parameter is available only if P7 is
equal to "REU" or "DIR".
Range:From 1 to 200 s.
RC Relative Cooling gain.
This parameter is available only if device is
configured with two control outputs and
A) Pb is different from 0 or.
B) device is in manual mode
Range: from 0.20 to 1.00
Note: When the device is working with
SMART algorithm and P37 is set to ON
the RC value is limited in accordance with
the selected type of cooling media:
- from 0.85 to 1.00 when P25 = AIR
- from 0.80 to 0.90 when P25 = OIL
- from 0.30 to 0.60 when P25 = H2O
OLAP Dead band/Overlap between H/C
outputs.
This parameter is available only if device
is configured with two control outputs and
A) Pb is different from 0 or.
B) device is in manual mode
Range: from -20 to 50 % of the
proportional band.
A negative OLAP value shows a dead
band while a positive value shows an
overlap.
RL Set point low limit
Range: from min. range value (P3) to RH.
Note: When P3 has been modified, RL
will be realigned to it
RH Set point high limit
Range:from RL to full scale value (P4)
Note: When P4 has been modified, RH
will be realigned to it.
GR.A1 First gradient used to increase the set
point when the measured value is
lower then
CH.GrCH.Gr
CH.GrCH.Gr
CH.Gr
Range: from 1 to 100 units per minutes.
Above this value the display shows “INF”
meaning that the transfer will be done as
a step change.
CH.Gr Threshold for automatic gradient
selection.
Range: within the input range.
GR.A2 Second gradient used to increase the
set point when the measured value is
higher then
CH.GrCH.Gr
CH.GrCH.Gr
CH.Gr
Range: from 1 to 100 digits per minutes.
Above this value the display shows “INF”
meaning that the transfer will be done as
a step change.
GR.b1 First gradient used to decrease the set
point when the measured value is
lower then
CH.GrCH.Gr
CH.GrCH.Gr
CH.Gr
For other details see GR.A1 parameter.
GR.b2 Second gradient used to decrease the
set point when the measured value is
higher then
CH.GrCH.Gr
CH.GrCH.Gr
CH.Gr
For other details see GR.A2 parameter.
OLH Output high limit
This parameter is not available when P5 =
SM.CL or SM.OL.
Range:
- From 0 to 100% when the device is
configured with one control output.
