Description
Defines the fifth underload point.
See parameter 37.21 ULC underload point 1
Underload point.
Defines the first of the five points on the Y-axis that together
with the corresponding point on the X-axis
table point 1...37.15 ULC speed table point 5
speed table point 5...37.20 ULC frequency table point
define the overload (higher) curve.
At each of the five points the value of the underload curve
point must be equal to or smaller than the value of the
overload curve point. See parameter
point 1.
Overload point.
Defines the second overload point.
See parameter 37.31 ULC overload point
Overload point.
Defines the third overload point.
See parameter 37.31 ULC overload point
Overload point.
Defines the fourth overload point.
See parameter 37.31 ULC overload point
Overload point.
Defines the fifth overload point.
See parameter 37.31 ULC overload point
Overload point.
Defines the time period for which time the monitored signal
must remain continuously below the overload curve.

Defines the time period for which time the monitored signal
must remain continuously above the underload curve.

Parameter values for process PID control.
The drive output can be controlled by the process PID. When
the process PID control is enabled, the drive controls the
process feedback to the reference value.
Two different parameter sets can be defined for the process
PID. One parameter set is in use at a time. The first set is
made up of parameters 40.07...40.50, the second set is
defined by the parameters in group
The binary source that defines which set is used is selected
by parameter 40.57 PID set1/set2

To set the PID customer unit, select Menu - Primary settings
- PID - Unit on the panel.
Displays the output of the process PID controller. See the
control chain diagram on page 431.
This parameter is read-only.
