Extended functions of group A
Group A comprises a variety of functions, among them functions for adjusting the frequency set value,
functions for setting up multistage speed settings, as well as functions for configuring parameters for a DC
brake, etc.

Function description / parameter setting range

Setting range 0.5Hz–360Hz (resolution +/-0.1Hz).
The frequency can be set using the following methods:
Using F 01 and A 20 : Enter the parameter 02 under A 01 .
By means of a voltage of 0–10 V or a current of 4–20mA at input
terminals O or OI. Enter the parameter 01 under A 01 .
Using the digital input terminals configured as CF1–CF4. After
selecting the desired frequency stage by applying logic levels to the
Y
digital inputs, the frequency for the selected stage can be entered.
(Note: Multistage speed settings can also be entered using A21 - A35 ).
The frequency set value display is independent of the method with
which the set value was entered.
Setting range 0.1s–3000s. (Resolution 0.1s in the range of 0.1 through
Y
999.9. Resolution 1s in the range of 1000 through 3000).
Setting range 0.1s–3000s. (Resolution 0.1s in the range of 0.1 through
Y
999.9. Resolution 1s in the range of 1000 through 3000).
After pressing the RUN key the motor starts in forward running mode
N
(parameter 00) or in reverse running mode (parameter 01).

Main functions
There are three different ways to set the output frequency:
00: NOT IN USE
N
01: using analog input terminals O (0-10V) or OI (4-20mA)
02: using functions F 01 or A 20
The command for starting the motor can be issued via:
01: the digital inputs configured as FW or RV
N
02: the RUN key on the digital operator
The base frequency is the frequency where the output voltage has its
N
maximum value. Setting range 50Hz–360Hz.

Chapter 8 – Using the digital operator
If there is a need for a frequency
range with a constant voltage that
lies beyond the base frequency
entered using A 03 , this range can
be configured using A 04 . The
f
maximum frequency must not be
smaller than the base frequency
(Setting range 50Hz–360Hz).
