Programmable relay output
The drive has one programmable relay output. It is possible to add three additional
relay outputs with the optional MREL-01 output relay module. For more information,
see
MREL-01 output relay 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 the 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).
