DeviceNet Serial Communication Bus
Parameter group for DeviceNet-specific parameters.
13-
Smart Logic
Parameter group for Smart Logic Control
14-
Special Functions
Parameter group for configuring special adjustable frequency drive functions.
15-
Drive Information
Parameter group containing adjustable frequency drive information such as operating
data, hardware configuration and software versions.
16-
Data Readouts
Parameter group for data readouts, such as current references, voltages, control, alarm,
warning and status words.
18-
Info and Readouts

the output frequency of the unit.
21-
Extended Closed-loop
Parameters for configuring the three extended closed-loop PID controllers.
22-
Application Functions
These parameters monitor water applications.
23-
Time-based Functions
These parameters are for actions to be performed on a daily or weekly basis, such as
different references for working hours/non-working hours.
25-
Basic Cascade Controller Functions
Parameters for configuring the basic cascade controller for sequence control of multiple
pumps.
26-
Analog I/0 Option MCB 109
Parameters for configuring the Analog I/0 Option MCB 109.

Table 6.1: Parameter Groups
Parameter descriptions and selections are displayed on the Graphic LCP or Numeric LCP in the display area (See Section 5 for details.) Access the
parameters by pressing the [Quick Menu] or [Main Menu] key on the control panel. The quick menu is used primarily for commissioning the unit at start-
up by providing those parameters necessary to start operation. The main menu provides access to all the parameters for detailed application programming.
All digital input/output and analog input/output terminals are multifunctional. All terminals have factory default functions suitable for the majority of water
applications but if other special functions are required, they must be programmed in parameter group 5 or 6.
