Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP) BACnet points list

Updated 4 November 2026

Short answer

The MD5 VFD speaks native BACnet MS/TP on its built-in RS-485 port (embedded fieldbus). The object list is fixed: relay and digital input status, relay and analog output commands, run/stop, direction, run enable and override commands, two references, drive measurements, energy and run-time counters, fault history and a parameter mailbox (AV25/AV26 with BV15/BV16). Most commands only act when the matching drive parameter is set to COMM.

This page lists 72 BACnet objects for the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP) — 28 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Daikin Applied’s own free documentation, linked below.

BMS integration notes: Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP)

Integration in brief

Set 9802 = BACNET (5), the baud in 5303, the device instance in 5311/5317 and the MAC in 5302 (set 5302 last). Set 1001 = COMM and 1103 = COMM, then command BV10 RUN/STOP CMD and AV16 INPUT REF 1. Read BV0, BV2, AV1, AV4 and AV6, and reset faults with BV14. Set 3018/3019 for comm-loss behaviour.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Enable & remote start

Start/stop (BV10) needs parameter 1001 = COMM (EXT1) or 1002 = COMM (EXT2); INPUT REF 1 (AV16) needs 1103 = COMM; run enable (BV12) needs 1601 = COMM; fault reset (BV14) needs 1604 = COMM. BV18 CTL OVERRIDE CMD hands drive control to BACnet from its normal source; panel HAND has priority over it.

Heartbeat & communication loss

3018 COMM FAULT FUNC sets what the drive does on a communication loss (0 not selected, 1 fault, 2 constant speed 7, 3 last speed) and 3019 COMM FAULT TIME sets the delay before it acts.

Sensors & values from the BMS

AV27 EXT PID STPT lets the BMS write the external PID setpoint when 4210 = 19 (INTERNAL).

Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the MD5 Variable Frequency Drive (embedded BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP)

How many BACnet points does the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP) have?

This list has 72 BACnet objects: 2 analog inputs, 2 analog outputs, 28 analog values, 12 binary inputs, 6 binary outputs, 22 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP) BACnet points are writable?

28 of the 72 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.

Where is the official Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP) BACnet documentation?

The source is Daikin Applied MD5 Variable Frequency Drive Controller - Operations Manual (OM 1191-2), revision 2023-08, published free by Daikin Applied at https://tahoeweb.daikinapplied.com/api/general/DownloadDocumentByName/media/OM%201191-2.pdf.

What are the minimum BACnet points to integrate the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP)?

Start with BV 10 RUN/STOP CMD (Start/stop from the BMS); AV 16 INPUT REF 1 (Speed reference in %); BV 14 FAULT RESET (Reset a tripped drive); BV 0 RUN/STOP ACT (Running status); BV 4 HAND/AUTO ACT (Shows if the panel has the drive in Hand); AV 1 OUTPUT FREQ (Output frequency in Hz); AV 4 CURRENT (Motor amps); AV 6 POWER (Drive power in kW); BV 2 FAULT ACT (Any active drive fault); AV 18 LAST FLT (Most recent fault code).

How do I enable BMS control of the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP)?

Start/stop (BV10) needs parameter 1001 = COMM (EXT1) or 1002 = COMM (EXT2); INPUT REF 1 (AV16) needs 1103 = COMM; run enable (BV12) needs 1601 = COMM; fault reset (BV14) needs 1604 = COMM. BV18 CTL OVERRIDE CMD hands drive control to BACnet from its normal source; panel HAND has priority over it.

Does the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?

3018 COMM FAULT FUNC sets what the drive does on a communication loss (0 not selected, 1 fault, 2 constant speed 7, 3 last speed) and 3019 COMM FAULT TIME sets the delay before it acts.

Can the BMS supply sensor values to the Daikin Applied MD5 Variable Frequency Drive (embedded BACnet MS/TP)?

AV27 EXT PID STPT lets the BMS write the external PID setpoint when 4210 = 19 (INTERNAL).

How do I check these points on the real MD5 Variable Frequency Drive (embedded BACnet MS/TP)?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
