Introduction

The CM-H8M-8108-85KV brushless power system is an industrial version power system that adopts a single-axis load of 2.5-3.5kg. 12 The blinking of the light The maximum pulling force of a single axis is 7.4kg and is suitable for a 30mm carbon fiber tube arm with an overall waterproof level protection rated at IP45. The efficient heat dissipation provides a one-stop power solution for small professional aerial photography, police, security, surveying and mapping, emergency, and other multi-field rotor drone applications. FOC ESC adopts CAN communication, dual redundant design of digital throttle and PWM throttle, with power-on self-test, fault storage, over-current protection, stall protection, and other protection functions.

Precautions

• Please stay away from crowds, high-voltage lines, obstacles, etc. when using, and be sure to follow safety regulations when using.

• The power system contains an FOC drive ESC, which needs to strictly match the motor parameters. The program is unique. It is only suitable for one combination of propellers and is not compatible with
  multiple combinations at the same time. If you need to change it, please contact the manufacturer. Unreasonable combinations will trigger ESC protection and make it unusable.

• The ESC is equipped with a CAN function. When using the CAN function, the ESC ID and the throttle channel of the same aircraft cannot be the same, otherwise, the multiple ESCs will be recognized
  as the same.

• Do not bring Propellers for ground testing to avoid unnecessary danger.

• Be sure to connect all parts carefully. If the connection is poor, you may not be able to control the aircraft normally, or other unpredictable situations such as equipment damage may occur.

• If you need to weld the input and output wire plugs of the ESC, please ensure that the welding is reliable and use welding equipment with sufficient power.

• Do not use it when the external ambient temperature exceeds 50°C. The high temperature will destroy the ESC and may cause damage to the motor and cause the machine to explode.

• The steering of the power system has been set at the factory. Please observe the motor steering mark. It is not supported to change the sequence of the motor phase wires due to the packaging and sealing process.

• The motor temperature is measured by running the throttle at the rated point for 10 minutes, for reference only.

ESC protection function

This ESC is specially designed for industrial drones, without low-voltage protection and over-heat protection.

• Stall protection
  When the ESC detects that the motor is locked, the ESC will completely turn off the output and repeatedly try to restart the motor. Please land the aircraft as soon as possible if the motor is unable to be restarted. The power output can only be resumed after the power is turned off and restarted, and the fault is eliminated.

• Current protection
  When the instantaneous phase current abnormality reaches 100A, the ESC will turn off the output and keep trying to restart the motor. If the motor does not restart, it will return to normal after power on again.

• Over-heat warning
  A fault message will be sent out through the data interface when the MOS or capacitor temperature is higher than 100°C. Please land the aircraft in time or reduce the throttle output when the ESC reports an over-heat fault, if the temperature continues to rise, electronic components may be damaged.

• Low voltage protection
  This ESC has no low-voltage protection. Some electronic components of the ESC will work abnormally when the voltage falls below 24Vxs. Please land the aircraft in time.

• Throttle signal loss protection
  When the ESC detects that the throttle signal is lost, the output will be turned off immediately to avoid greater losses caused by the continued high- speed rotation of the propeller. After the signal is restored, the ESC will resume normal operation immediately.

ID setting

• If there is no requirement, the default factory ID of the ESC is 1, the throttle channel is 1, and the bus speed is 500KHz.
• This function requires the additional purchase of a DataLink data box.
• Before using this function, ensure that the computer system has installed Microsoft Visual C++ 2013 software in advance, otherwise, it cannot operate normally.

1. Connection
   • ESC—->DataLink data box “yellow gray green”—->”—CH1 CL1″;
   • Connect the data box to the computer via USB.
   • When changing the ID, please remove the Propeller to avoid danger.
   • For the same aircraft, different ESC IDs and throttles cannot be the same to avoid the same ID recognizing as one ESC when using the CAN function.

Fault data read

The ESC has its fault storage function to store the times upon powering on, flight time, and fault times information. It is convenient for flight fault analysis. This function needs to use a DataLink data box, serial port assistant, and DataLink host computer software.

Note:
DataLink software can be obtained from Hobbywing’s official website, dealers, Hobbywing sales, and Hobbywing after-sales.

• DataLink data box firmware version requirements: LINK-01.2.15-C or later; serial port assistant requirements: USB to TTL protocol; DataLink host computer software requirements: fault storage version. It can be obtained on the official website, WeChat official account, or after-sales service.

The DataLink box has three power supply methods (+5V), USB data cable, serial port assistant, and external power supply cable. You can choose one of the power supply methods, and you don’t need to repeat the power supply.

Note:
For detailed steps, please refer to the DataLink user manual.

1. Connection
   • Serial port assistant —-> DataLink data box “GND 5V TX RX” —-> “— + RX2 TX2” (please click here for the corresponding line sequence);
   • ESC—->DataLink data box “yellow gray green”—->”— CH2 CL2″, multiple ESCs can be used in parallel.
2. Software operation

Firmware upgrade

Firmware upgrade is divided into two ways: computer online upgrade and flight controller remote upgrade. It supports the online upgrade of multiple ESCs at the same time, and the upgrade port is CAN-ESC (Fast).

• The upgrade of the flight control needs to cooperate with the flight control(not explained here).
• This function needs to use a DataLink data box, special DataLink software for the upgrade package, and a USB data cable.
• DataLink data box version requirements, LINK-01.2.15-C or later; DataLink software can be obtained from Hobbywing’s official website, distributors, Hobbywing sales, and Hobbywing after-sales.
• Note: Please ensure that the computer system has installed Microsoft Visual C++ 2013 software before using this function, otherwise it cannot be used. An upgrade package usually only contains one program for one type of ESC. For other ESCs, please re-obtain the upgrade package for the corresponding ESC model.

1. Connection
   • Connect the computer and the DataLink data box with the USB data cable;
   • ESC—->DataLink data box “yellow gray green”—->”— CH1 CL1″.
2. Firmware acquisition
   • It can be obtained at the place of purchase, Hobbywing official website, dealers, Hobbywing sales, and Hobbywing after-sales offices.
   • Note: It can only be upgraded from the existing program, and software and hardware cannot be upgraded together.
