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” .

Programmable Relay Output
The drive has one programmable relay output . It is possible
to add three additional relay outputs with the optional Relay
Output Extension Module MREL-0 . For more information,
see MREL-01 Relay Output Extension Module User’s Manual
(3AUA0000035974 [English]) .
With a parameter setting it is possible to choose what
information to indicate through the relay output: Ready,
running, fault, alarm, etc . The update time for the relay output
is 2 ms .
A value can be written to a relay output through a serial
communication link .

Frequency Input
Digital input DI5 can be programmed as a frequency input .
Frequency input (0…16000 Hz) can be used as external
reference signal source . The update time for the frequency
input is 50 ms . Update time is shorter when information is
transferred to the application program (50 ms -> 2 ms) .
