You have a two part question, allow me to address the larger issue first.
FP86 is premium efficient which is fine to use with vfd but you have to consider the following:
Premium efficient motors without INVERTER GRADE insulation meet minimum NEMA®† MG-1, Section IV, Part 31.4.4.2. These motors can be used with Variable Frequency Drives (with a reduced warranty period) under the following parameters:
I'd recommend an actual VFD duty motor to void any issues with inverter use.
Like the HK18

Now as far as use in HVAC and belt driven:
This is a sticky question and one only your application engineer can answer because of the many variables.
First you have to be positive ODP is ok for your application or you'll destroy the motor and warranty with it.
Second you have to make sure your belted stress load isn't more than the bearing can manage as typically you'd want roller bearings instead of ball bearings on the shaft end for belted applications.

- On NEMA®† frame motors, 10:1 speed rating on variable torqueloads & 4:1 speed range on constant torque loads.
- Then there is a cable distance according to voltage and switching frequency to keep in mind.
