7.2. Control functions (for pumps with brushless
DC motor)
7.2.1. Speed control
DC-B (constant speed)
The motor drives the pump at a constant, unchangeable speed
across the entire permissible pressure range.
.29DC-B (regulated speed)
The motor drives the pump at a changeable speed between n
min
and n
max
. Speed is specified via the control voltage.
7.2.1.1. Speed input (.29 versions)
The speed range of n
min
… n
max
is shown scaled to the control
voltage U
c
:
▪
Uc
min:
0.1V
▪
Uc
max:
5.0V
If the control voltage is less than Uc
min
, the motor is
OFF.
Fig. 13: Control-voltage/speed curve (standard)
Speed is specified through the 8-pin controller connection, Pin 2
(see Table in Fig. 12).
Optional analog settings for control voltage input
The following additional settings can be made at the factory upon
request:
▪
Modify control voltage values U
cmin
and U
cmax
▪
If the control voltage is less than Uc
min
, the motor will be
ON.
