Digital Outputs - Eaton M-Max Series User Manual

Parameters
Digital Outputs (P5)
The M-Max series frequency inverters have three digital
outputs in different specifications:
Relay RO1: N/O contact R13–R14, control signal terminals
●
22 and 23
Relay RO2: changeover contact R21–R22 (N/C contact,
●
control signal terminals 25 and 24)/R21–R24 (N/O contact,
control signal terminals 25 and 26)
Transistor output DO: control signal terminal 13 (DO–).
●
Control signal terminal 20 (DO+) = Input of the supply
voltage for the transistor output
Notes on electrical connections are found on Pages 44
and 45.
The messages listed under parameter P5.1 can be assigned
multiple times. These are independent of the selected
control level and operating mode.
