Quick Start Guide

Getting started with the HV Pro ESC.

In the Box

The following items are included in the box with each APD HV Pro ESC.

  • 1 x APD HV Pro Electronic Speed Controller

  • 1 x Quick Start Guide Card

Required for Setup (Not Included):

  • 2 x Power Cable (8 - 12 AWG)

  • 3 x Motor Cable (8 - 12 AWG)

  • 1 x Signal Telemetry Cable (3 Pin 0.1" Female)

  • 1 x Micro USB Cable

Firmware Check

Before starting up the HV Pro ESC, it is important that the ESC contains the latest firmware, ensuring maximum performance and that the most up to date features are included.

The APD ESC Configuration Tool is used to update ESC firmware, adjust ESC settings and view/manage logs stored from previous device usage.

The latest Configuration Tool can be downloaded from here: Download

  1. Download the Configuration Tool to a Windows PC from the link supplied

  2. Connect the HV Pro to the computer using a Micro USB cable (not included), and run the Configuration Tool

  3. (Optional) Make sure the firmware is updated if supplied by APD

  4. Check relevant settings are applied

  5. Disconnect the ESC, perform the wiring setup

Wiring the ESC

When wiring the HV Pro ESC, we recommend you use highly flexible and high-temperature silicon insulation for the power cables. This ensures unnecessary stress is not applied to the ESC terminals, and maximum thermal reliability is achieved.

8 AWG, 10 AWG or 12 AWG wires are recommended, depending on the current draw of your application

If the final desired ESC location is further than 1 meter from the power source, we recommend the use of a local capacitor bank (sold separately) to reduce DC bus voltage ripple. This also reduces voltage spikes occurring during regenerative braking.

If running the HV Pro from a power supply that can not absorb current (when the HV Pro is regen braking), this can cause damage to the unit or supply if the Synchronous Rectification is enabled. It can be disabled in the configuration tool, under the Advanced tab.

Input voltage ripple must be managed to a maximum of +/- 5% of your total input to the ESC. Longer input leads require a larger capacitor bank capacitance

Assembly Instructions

The following images are a recommended soldering technique for the HV Pro with no capacitor bank connected.

Powering Up

Before powering on the HV Pro unit, be sure to check all the power connections for cold solder joints. In addition to this, test the motor phase cables for shorts with a multi-meter.

Make sure input polarity is correct! Connecting the ESC incorrectly will damage the unit, and void any APD warranty.

End Points

In order for your ESC to perform correctly when using a PWM input, make sure that the end-points coming from the receiver are between 1000-1020 uS for the lower end-point and 1980-2000 uS for the upper-end point.

If the lower end-point is above 1020 uS, the ESC will not arm. Similarly, if the receiver is outputting less than 1980 uS, you will not experience the full power range.

The ESC's can receive up to 500Hz PWM, with standard TTL 3.3V or 5V inputs. If the input voltage is less than 2.7V, the drive voltage of the receiver is not high enough and the ESC will not respond to signal inputs.
