Setting F: Through Mode
When set to F, an input does not affect any drive function, but the input level can still be read out by a PLC via APOGEE
FLN, BACnet, MEMOBUS/Modbus, or Metasys N2 communications.
Setting 16: Differential PI Feedback
If an analog value is set for this function, the PI controller is set for differential feedback. The difference of the PI feedback
input value and the differential feedback input value builds the feedback value used to calculate the PI input.
n
H5-01: Drive Slave Address
Sets the drive slave address used for communications.
Note:
Cycle the power after changing this parameter to enable the new setting.

Each slave drive must be assigned a unique slave address for serial communications to work. Slave addresses do not need to
be assigned in sequential order, but no two drives may share the same address.
n
H5-02: Communication Speed Selection
Sets the communications speed for APOGEE FLN, BACnet, MEMOBUS/Modbus, and Metasys N2.
Note:
1. Cycle the power after changing this parameter to enable the new setting.
2. When Metasys N2 communications are selected (H5-08 = 1), selecting a baud rate other than 9600 bps will trigger an oPE29 error.
3. When APOGEE FLN (P1) communications are selected (H5-08 = 2), selecting a baud rate other than 4800 bps will trigger an oPE29
error.
4. When BACnet communications are selected (H5-08 = 3), selecting 115200 bps (Setting 8) will trigger an oPE29 error.
