Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP) BACnet points list
Updated 12 November 2026Unofficial source
The HVAC Drive H300 has BACnet MS/TP on board. Its fixed object list covers drive analog and digital I/O, a commandable speed reference and run-forward command, reset, output current, torque, frequency, speed and power, status word and last trip, two PID loops, filter-change timers, an energy meter and ten user-selectable AVs that map any drive parameter.
This page lists 57 BACnet objects for the Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP) — 30 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Nidec Control Techniques’s documentation hosted by BACnet International, not by Nidec Control Techniques itself, so treat it as unofficial.

Integration notes
- Object names are listed as printed, including the #AI_01-style prefix.
- AV 28-37 map drive parameters chosen in Pr 29.010-29.019; their access follows the mapped parameter (printed R/W).
- Binary I/O 1-3 are bi-directional; each can be an input or an output at a time.
- The PICS prints the BV descriptions copied from the BO rows; BV descriptions here follow the object names.
- The SI-BACnet IP option module uses a different AV numbering (see that list).
- Object instantiation is static; objects cannot be created or deleted.
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 HVAC Drive H300 (onboard BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP)
How many BACnet points does the Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP) have?
This list has 57 BACnet objects: 2 analog inputs, 2 analog outputs, 34 analog values, 7 binary inputs, 6 binary outputs, 6 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP) BACnet points are writable?
30 of the 57 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 Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP) BACnet documentation?
Nidec Control Techniques does not publish it on its own website. This list comes from H300 PICS BACnet V1 R15, revision 2023-11-14, a copy hosted by BACnet International at https://www.bacnetinternational.net/catalog/manu/nidec%20control%20techniques%20ltd./H300_PICS_BACNET_V1_R15.pdf. Ask Nidec Control Techniques or its representative for the current revision.
What are the minimum BACnet points to integrate the Nidec Control Techniques HVAC Drive H300 (onboard BACnet MS/TP)?
Start with BV 3 #BV_03 Drive Run Fwrd (Run forward command); AV 4 #AV_04 Speed Ref (Speed reference, Hz); BV 6 #BV_06 Drive Reset (Trip reset (write active)); BI 7 #BI_07 Drive Binary IP7 (Drive enable input state); AV 8 #AV_08 Output Frequency (Output frequency, Hz); AV 6 #AV_06 Output Current (Motor current, A); AV 10 #AV_10 Output Power (Output power, kW); BV 4 #BV_04 Drive Healthy (Drive healthy (no trip)); BV 5 #BV_05 Drive Warning (Drive warning active); AV 13 #AV_13 Last Trip (Last trip code).
How do I check these points on the real HVAC Drive H300 (onboard 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.
