The two relay outputs (control signal terminals 22 to 26)
enable the frequency inverter to generate galvanically
isolated feedback signals in control circuits with other
potentials:
●
maximum switching capacity: 250 Vdc, 0.4A (DC voltage),
●
maximum switching capacity: 250 Vac, 2A (AC voltage).
With voltages greater than 48V, you should fasten the
connection cables of the relay in the opening on the right
(housing).

The functions for which parameters can be defined are
described in “Digital Outputs (P5)” on Page 78.
The factory setting causes N/O contact R13/R14 (control
signal terminal 22/23) of relay RO1 to indicate operation
(RUN).
N/O contact R21/R24 (control signal terminal 25/26) of relay
RO2 indicates a detected fault (ERROR = FAULT).
If the supply voltage of the frequency inverter is switched off
upon the occurrence of an error message, the N/O R21/R24
opens again (relay drops out).
The functions for which parameters can be defined for both
relays RO1 and RO2 are described in “Digital Outputs (P5)”
on Page 78.
