n H4-07, H4-08: Multi-Function Analog Output Terminal FM, AM Signal Level Selection
Sets the voltage output level of U parameter (monitor parameter) data to terminal FM and terminal AM using parameters
H4-07 and H4-08.
Set jumper S5 on the terminal board accordingly when changing these parameters.

u H5: Serial Communication (APOGEE FLN, BACnet, MEMOBUS/Modbus,
and Metasys N2)
Serial communication is possible in the drive using the built-in RS-422/RS-485 port (terminals R+, R-, S+, S-) and
programmable logic controllers (PLCs) or similar devices running the APOGEE FLN, BACnet, MEMOBUS/Modbus, and
Metasys N2 protocols.
The H5-oo parameters set the drive for APOGEE FLN, BACnet, MEMOBUS/Modbus, and Metasys N2 communications.
Refer to the different communication protocol chapters for detailed descriptions of the H5-oo parameters.
