The following items are included in the box with each APD UHV ESC.
1 x APD UHV Electronic Speed Controller
5 x M6 (16mm) Cable Lugs (Wurth 5580616)
1 x Signal Connector with Crimp Terminals (Harwin M80-4601442)
1 x Quick Start Guide Card
Required for Setup (Not Included):
2 x Power Cable (7 or 8 AWG)
3 x Motor Cable (7 or 8 AWG)
1 x Micro USB Cable
Before starting up the UHV 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.
Download the Configuration Tool to a Windows PC from the link supplied
Connect the UHV to the computer using a Micro USB cable (not included), and run the Configuration Tool
(Optional) Make sure the firmware is updated if supplied by APD
Check relevant settings are applied
Disconnect the ESC, perform the wiring setup
When wiring the UHV ESC, we recommend you use high-temperature silicon insulation for the power cables. This ensures maximum thermal reliability is achieved.
The UHV ESCs contain an electrolytic capacitor bank that is designed for up to 3 meters of input power cable. Longer runs of cable should have the DC bus voltage measured to ensure this remains below +-10% of the input voltage. Extra capacitance can be added to minimise ripple.
When attaching cables to the screw terminals of the ESC, care must be taken not to over-torque the terminal and cause a shear. The maximum recommended torque to be used when attaching the cables is 3.9Nm.
Before powering on the UHV 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.
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.
