1.4 Usage Instructions
1.4.1 Cable Connection Procedure
1. Switch R1 and R2 of the blue DIP switch in CAN1 channel ON the left side of the CAN analyzer to the upper OFF position, and R1 and R2 of the red dip switch in CAN2 channel on the right side to the lower ON position. There must be two 120 ohMs terminal resistors on the normal CAN bus, otherwise it will affect the normal operation of the CAN bus, and the actual application resistance can be modified.
2. Connect CANH and CANL in the CAN1 channel of the analyzer with signal lines as A group, where H terminates with signal line a and L terminates with signal line B, as shown in Figure A.
3. Connect the connected CANH and CANL signal line interface 1 to the position of blue debugging board A, the interface 2 of the CAN bus steering gear to the position of blue debugging board B (according to the circuit diagram to distinguish the pins), and the interface 3 of the USB cable to the position of CAN analyzer C. As shown in Figure b.
4. Connect port 4 of the USB cable to the PC, power on the power port, and then open desun CAN steering gear unified upgrade software V1.0.2.
1. Click to start the CAN box.
2. Select the CAN channel corresponding to the steering gear from the CAN port number.
3. Click to connect the CAN port.
4. Click the Angle value in the quick test area below the software to perform Angle debugging on the target steering gear.
Note: When the software version changes, you need to load the upgrade file of the steering gear and click Start upgrade. When the version changes, you need to do it
Upgrades; If you need to rewrite the ID and rewrite the ID, you need to click Restart after the change.
1.5 Common Faults
1.5.1 Faults
Undesirable phenomenon | Possible cause |
non-function | The signal line is damaged, the motor is disconnected, the chip is false welded, the program is not burned or burned incorrectly |
Slow reaction, severe fever | Motor overcurrent, replace the steering motor |
Turn in one direction and get stuck | The positive and negative terminals of the motor or potentiometer are connected incorrectly |
Heavy hand feel | Gear assembly is not smooth, bottom cover pressed to PCBA, short circuit damage inside the motor, excessive grease |
Steering gear jitter | Gear assembly is not smooth, potentiometer damage, program problems |
Loud noise | Gear less oil, stuck teeth, skipping teeth, teeth damage |
Large current | The line sequence or motor line is reversed, the gear is stuck, the bottom cover is short with PCBA, and the tooth box is tight, resulting in the parameter mismatch and can not go to the target position |
Steering engine won't return to center | Potentiometer damaged or poor incoming material, potentiometer and output tooth connection is large, output tooth and customer rocker arm or connecting rod is large or stuck |
Torque deviation is large | There is deviation between selection and specification requirements, and the gear is overheated and worn for a long time |
Large angular deviation | Potentiometer damage or poor incoming material, potentiometer and output tooth connection virtual position is large, the control signal does not meet the specification requirements |
1.5.2 Frequently Asked Questions
Question 1: The steering gear is fixed on the product, and the positioning deviation is large with the housing?
Answer 1: The steering gear assembly is positioned at the center of the output tooth circle, and the ear holes on both sides are fixed as far as possible.
Question 2: The plastic gear of the steering machine is not impact resistant, easy to skip teeth?
Answer 2: It is necessary to consider the steering gear of the clutch tooth to apply, to avoid the external impact of the product is greater than the blocked torque.
Question 3: The output teeth of the steering gear are damaged by external impact, and the output teeth are not strong enough?
Answer 3: Try to use the steering wheel and product structural parts to support the external impact, to avoid the small output teeth to bear its impact greater than the steering gear torque.
1.5.3 Precautions
1, please use within the range of working voltage and current, do not overvoltage or overcurrent, so as to avoid burning out or internal damage to the steering gear.
2, please strictly follow the wiring procedure before wiring, so as not to have no function or can not work normally.
3, the use of large torque steering gear must be careful to prevent personal injury caused by misoperation.
4, remember not to add a new steering gear to the bus when the steering gear is working.
5, this product is a high-precision product, do not manually turn the steering wheel or swing arm, so as to avoid internal damage.
6, do not run the steering gear under ultra-high load, try to choose the appropriate running torque.
