"A" Group: Standard Functions Section 3-5
There are two ways for speed selection, that are "binary operation" and "bit
operation".
For binary operation (
A019=00), you can select 16 speeds by combination of 4
digital inputs. And for bit operation (
A019=01), you can select 8 speeds by
using 7 digital inputs. Please refer to the following figures for detailed explana-
tion.
Binary operation ("1"=ON)
Note When choosing a subset of speeds to use, always start at the top of the table,
and with the least-significant bit: CF1, CF2, etc
The example with eight speeds in the figure below shows how input switches
configured for CF1-CF3 functions can change the motor speed in real time.
A021

A035
Multi-speed freq. 1 to 15 (for both
motors)
Defines 15 more speeds, range
is 0.0 / start frequency to 400
Hz.

C169 Multi-speed/position determina-
tion time
Masks the transition time when
changing the combination of
inputs. Range is 0 to 200
