Programmable digital inputs
The drive has five programmable digital inputs. The update time for the digital inputs
is 2 ms.
It is possible to delay the state change of digital inputs with delays defined in group
Group 18: Freq in & tran out
. This enables very simple program sequences by
connecting several functions with the same physical wire, eg, to remove branches
and leaves from a pipe by running the fan in reverse before normal operation.
One digital input (DI5) can be programmed as a frequency input. See section
Frequency input on page 111 .
