Quick Start Guide
Getting started with the HV Pro ESC.
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
All HV_Pro units have the following pin configurations, alongside the relevant electrical properties.

When wiring the HV_Pro ESC, we recommend you use highly flexible and high-temperature silicone insulation for the power cables. This ensures unnecessary stress is not applied to the ESC terminals, and maximum thermal reliability is achieved. When operating the higher voltage units (85V+), it is recommended that a pre-charge system is used to avoid damage to the ESCs or connectors due to sparking from abrupt battery connections.
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.
The following images are a recommended soldering technique for the HV_Pro with no capacitor bank connected.
Phase cables soldered on motor side. Note which side of the tab each cable is soldered to.
Power cables soldered input side. Note both cables soldered on top of tabs.

The minimum requirements for controlling the throttle to the HV_Pro ESC are the PPM (Signal Input), VCC (Signal Power) and GND pins. This will ensure the ESC will correctly respond to throttle inputs. An absence of one of these three connections will result in the No Signal error tones while the unit is powered.
The USB is used when connecting the ESC to a PC for configuration and accessing data logs. When the USB is connected, the ESC will lock out the motor drive. Once the unit is powered on with main power, the USB will be locked out.
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.
- 1.Download the Configuration Tool to a Windows PC from the link supplied.
- 2.Connect the UHV to the computer using a Micro USB cable (not included), and run the Configuration Tool.
- 3.All the released firmware versions can be found under the Firmware tab once the ESC is connected. Ensure that the desired firmware (or latest) is installed on the unit.
- 4.Check relevant settings are applied. Settings can be saved to a file, for easy installation to other units.
- 5.Disconnect the ESC, perform the wiring setup.
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.
Powering up procedure:
- 1.Ensure the motor is connected to the phase connections.
- 3.Power on the signal source, ensure it is sending 0% throttle on startup of the ESC, end-point details below.
- 4.Power on the ESC.
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.
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.
