135 • HRVS-DN Communication (ModBus Protocol)
_______________________________________________________________________________________________
16.7 Actual Data (3X References & 4X references)
Actual data includes measured values such as voltage, current and insulation resistance. It includes both
logic and statistical information. All parameters are word (two bytes) parameters. The protocol supports only
reading of these parameters.
Parameter # is "1 based". The actual parameter address is 1 lower than parameter #. For example the
address of parameter #1 is 0 (30000).
The parameters have double mapping, at the following 3x & 4x references:
Note: Function 4 should be used to read 3x references and function 3 to read 4x references.
Parameter # (3x) # (4x) Comment
Logic Status 1 257 Logic status of HRVS-DN. 1 indicates:
d15: HRVS-DN Trip.
d14: Motor Stopped.
d13: Motor in Soft Stop Process.
d12: Motor in Start Process.
d11: Motor is Running.
d10: Motor is running with Closed By_Pass.
d9: Up_To_Speed. Like d10 and I reduced (once) below
115% of FLA.

Note: After bypass is closed, trip (d15) and running (d11),
can be ON together. See Trip_after_By-Pass setting
parameter at fault parameters page.
