Digital output (P5)
The frequency inverters of the M-Max
TM
series 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 page 48 and 49.
The messages listed under parameter P5.1 can be assigned
multiple times. These are independent of the selected control level
and operating mode.
