Parameter definition
The K1 relay output’s function can be configured using parameter P-18
(default setting = 1: RUN). Meanwhile, the new K2 relay output’s function
can be configured using parameter P-25 (default setting = Analog output
AO1).
￫
Depending on the type of load, we recommend the use of a
suppressor circuit when using the relay outputs (￫ figure 53,
page 80).
￫
Parameter P-25 must be set to a value between 0 and 7 in order
for the output to function as a digital output.
If the parameter is set to a value greater than 7, relay output K2
will not work properly.
￫
For detailed instructions on how to install the module, please
refer to instruction leaflet IL04012015Z.
NOTICE
Internal relay K1 is connected to the expansion module,
meaning it can only conduct a relatively low current (≦ 1A).
DANGER
Dangerous voltage!
Expansion module DXC-EXT-2RO1AO must not be placed into
operation until all mounting and installation work has been
completed (plugged in and connected to the DC1-S variable
frequency drive’s control signal terminals). Any other use will be
considered to be an inappropriate use.
