# HV Pro Configuration Options

## 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.  

{% hint style="info" %}
Default setting is: Size is Large <1000kV, Direction is normal
{% endhint %}

#### Motor Start Power

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

{% hint style="info" %}
Default setting is: Medium
{% endhint %}

#### Timing Advance

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

{% hint style="info" %}
Default setting is: Automatic
{% endhint %}

#### PWM Drive Frequency

Forces the output frequency to the motor. Recommended is auto setting enabled where possible.&#x20;

{% hint style="info" %}
Default setting is: Automatic
{% endhint %}

#### Throttle Response/Ramp Settings

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

{% hint style="info" %}
Default setting is: 50 % for both
{% endhint %}

### 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.

{% hint style="info" %}
Default setting is: 250 Amps
{% endhint %}

#### 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.

{% hint style="info" %}
Default setting is: 250 Amps
{% endhint %}

#### Temperature Limit

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

{% hint style="info" %}
Default setting is: 100 Degrees Celsius
{% endhint %}

#### Capacity Limit

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

{% hint style="info" %}
Default setting is: 25,000 mAh
{% endhint %}

#### 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.

{% hint style="info" %}
Default setting is: Hard Shutdown temperature cut off, None for the rest
{% endhint %}

### Logging Settings

Enable or Disable logging of data to the internal memory of the ESC.&#x20;

{% hint style="info" %}
Default setting is: Enabled
{% endhint %}

### Additional Settings

#### PWM Throttle Endpoints

Adjust the input ranges of the PWM endpoints, can either be manually adjusted or automatically.&#x20;

{% hint style="info" %}
Default setting is: Auto Detected
{% endhint %}

#### 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.

{% hint style="info" %}
Default setting is: Enabled
{% endhint %}

#### Feed-Forward Compensation

ESC will automatically add throttle when voltage drops occur to help maintain a linear throttle response.&#x20;

{% hint style="info" %}
Default setting is: Disabled
{% endhint %}

#### Motor Beep

Enable or Disable the motor beep status tones.

{% hint style="info" %}
Default setting is: Enabled
{% endhint %}

#### Input Signal Type

Depending on firmware supplied by APD, the input type can be forced between listed protocols.&#x20;

{% hint style="info" %}
Default setting is: Normal PWM
{% endhint %}
