CF1 – CF4: Multistage speed settings
Terminal function
Using the digital inputs configured as CF1 – CF4 one of up to 16 freely selectable frequencies (including the
set value) can be sent to the motor depending on which terminals are activated or deactivated (refer to table
below). It is not necessary to use all four multistage speed setting terminals at the same time. If you need for
example only up to eight different frequencies it is sufficient to configure only CF1 – CF3; if only up to four
different frequencies are needed only 2 multistage speed setting terminals have to be configured.
The multistage speed settings have a higher priority than most of the other means of providing the set value.
Only when the jogging run is activated the jogging frequency priority is even higher than the priority of the
multistage speed settings. The multistage frequencies can be activated using the inputs CF1 – CF4 at any
time and need not be enabled in any way.

Configuration
A 21 – A 35
C 01 – C 05
Configure one or more of the digital inputs 1 – 5 as CF1 – CF4 input by entering one or more parameters
under C 01 – C 05 (parameter setting range is 02 – 05).
Following this, the multistage frequencies can be programmed by one of two ways:
A) Enter the multistage frequencies under A 21 – A 35.
B) Activate those multistage speed inputs that are necessary for the desired frequency to be configured
(refer to table above) and enter the desired frequency under F 01 (note that the motor must be stopped
first e.g. using the STOP key or deactivating the FW input). The entered frequency value must be stored
using the STR key.
Remarks
• If you want one ore more of the multistage frequencies to be greater than 50Hz the maximum frequency
has to be raised first using A 04.
• A multistage speed setting of 0 (inputs CF1 – CF4 are all deactivated) corresponds to the frequency set
value. This set value can be configured either using the built-in potentiometer, the terminals O
respectively OI, or by configuring F 01 and A 20.
