• Resulting setpoint
The reading is a percentage of the external setpoint
range.
• Motor load
The reading is a percentage of the range between 0
and 200 % of the maximum permissible load at the
actual speed.
• Motor current
The reading is a percentage of the range between 0
and 200 % of the rated current.
• Limit 1 exceeded and Limit 2 exceeded
The Limit-exceeded function is typically used for
monitoring of secondary parameters in the system. If
the limit is exceeded, an output, warning or alarm is
activated.
• Flow rate
The reading is a percentage of the range between 0
and 200 % of the nominal flow.
Factory setting
See section 30. Factory settings.
13.14 "Controller" ("Controller settings")
The pumps have a factory setting of gain, K
p
, and
integral time, T
i
.
However, if the factory setting is not the optimum
setting, you can change the gain and the integral
time.
• Set the gain within the range from 0.1 to 20.
• Set the integral time within the range from 0.1 to
3600 seconds. If you select 3600 seconds, the
controller functions as a P controller.
Furthermore, you can set the controller to inverse
control. This means that if the setpoint is increased,
the speed is reduced. In the case of inverse control,
the gain must be set within the range from -0.1 to
-20.
