RUN
1 CONTROL MODE=1
G25.1.1 / Control
mode
0 – 1
It allows to select the control mode according to the following information:
OPT. DESCRIPTION
FUNCTION
0 MANUAL
To be used in the commissioning
and tests. It is not thought to be
used in permanent operation since
the protections are not enabled. In
this way the display will show
„OVERRIDE MANUAL‟
With this option it is necessary to
operate from the keypad, but the
speed reference can be entered
using an analogue input or by
keypad.
1 PUMP
The drive will start in pump control
mode. Selection of automatic
operation in regulation mode (it
allows to control flow, pressure).
YES
2 MAN SPD REF= LOCAL
G25.1.2 / Source
selection for
speed reference in
manual mode
LOCAL
AI1
AI2
It allows to select the source for the manual speed reference when the
digital input configured as „MANUAL PROTECTED‟ or the „OVERRIDE
MANUAL‟ are closed according to the following table:
OPT. FUNCTION
LOCAL Speed reference entered by keypad
AI1 Reference by Analogue Input 1
AI2 Reference by Analogue Input 2
YES
3 MAN SPEED=+0.0%
MANUAL SPEED
G25.1.3 / Value of
speed reference
for LOCAL source
in manual mode
-250% to
+250%
It is set as % of the motor speed.
This parameter allows to set the value of the speed reference in manual
mode (protected or not) whether the speed reference is the main
reference or the alternative reference, always that we talk about LOCAL
mode. For that reason, it is possible to select one analogue input as main
speed reference in G25.1.2 (AI1) and configure one alternative speed
reference by keypad in G25.1.4 setting this parameter to „LOCAL‟. For
example, when the digital input configured as Alternative Manual Speed
is activated, the speed of the main pump will be the value set in this
parameter by keypad. This functionality is interchangeable between main
and alternative speed references, that means, we can select the main
speed reference by analogue input and the alternative by keypad and
vice versa.
YES
4 ALT MAN S R=LOCAL
G25.1.4 / Source
for the Alternative
speed reference in
manual mode
LOCAL
AI1
AI2
It allows to select the source for the alternative speed reference between
the keypad or the analogue inputs, according to the following table:
OPT. FUNCTION
LOCAL Speed reference introduced by keypad
AI1 Reference by Analogue Input 1
AI2 Reference by Analogue Input 2
NO
