UHV and HV Pro Configuration

To configure settings on the HV Pro and UHV ESCs, the APD Config tool can be downloaded and used with a Micro USB cable (not included). Connect the ESC to the PC, with no power from external sources.

Configuration Options

This section of the guide outlines the various configurable elements of the UHV and HV Pro through the configuration tool, along with their default factory settings. All settings are persistent between ESC power cycles.

Motor Drive Settings

Motor Type and Direction

The type of motor that is connected to the ESC (small or large based on kV), and the desired direction the motor will be operated with.

Default setting is: Size is Large <1000kV, Direction is normal

Motor Start Power

The speed the motor will spool up to immediately after arming the ESC.

Default setting is: Medium

Timing Advance

Increased timing advance can reduce ESC running temperatures with some motors. The recommended setting is auto.

Default setting is: 15 Degrees

PWM Drive Frequency

Forces the output frequency to the motor. Recommended is auto setting enabled where possible.

Default setting is: 30 KHz

Throttle Response/Ramp Settings

Acceleration and braking rates for the ESC, which are applied on every change of throttle input to the ESC.

Default setting is: 50 % for both

ESC Limits

Bus Current Limit

The upper current limit the ESC can reach on the input from the power supply. Configurable from 150 to 400 Amps, depending on ESC model.

Default setting is: 300 Amps

Phase Current Limit

The upper current limit the ESC can reach on the output to the motor. Configurable from 150 to 400 Amps, depending on ESC model.

Default setting is: 300 Amps

Temperature Limit

The temperature limit for the ESC as measured internally. Configurable to ranges from 75 to 130 degrees Celsius.

Default setting is: 100 Degrees Celsius

Capacity Limit

The lower limit for the power supply input, to avoid under-voltage of battery packs.

Default setting is: 50,000 mAh

Cut Off Response

The response to going over/under the preset limits, with separate responses for different limits. Options are None, Hard Shutdown, Gradual Shutdown, 75% Power Limit, 50% Power Limit and 25% Power Limit.

Default setting is: Hard Shutdown temperature cut off, None for the rest

Logging Settings

Enable or Disable logging of data to the internal memory of the ESC.

Default setting is: Disabled

Additional Settings

PWM Throttle Endpoints

Adjust the input ranges of the PWM endpoints, can either be manually adjusted or automatically.

Default setting is: Auto Detected

Synchronous Rectification

Toggle the regenerative braking functionality of the ESC. Enabled results in the return of power up to 10% of the maximum current capacity of the ESC (model dependant). Disabled results in no return of power to the supply, but reduces the thermal performance of the ESC. This must be disabled if running the ESC on a power supply that cannot absorb power.

Default setting is: Enabled

Feed-Forward Compensation

ESC will automatically add throttle when voltage drops occur to help maintain a linear throttle response.

Default setting is: Disabled

Motor Beep

Enable or Disable the motor beep status tones.

Default setting is: Enabled

Input Signal Type

Depending on firmware supplied by APD, the input type can be forced between listed protocols.

Default setting is: Normal PWM
