Curtis Drive F2A parameter adjustment guide

1. Scope of Application

This article is relevant to debugging and configuring the Curtis-F2A.

Second, Debugging Resources

  1. Software debugging:



This software license code can only be installed and used on one computer. If it is used on other computers, it needs to be re-authorized, and the license activation code is charged.

  1. PEAK (No license is required for this software)

Note: No license is needed for the software PEAK

Software Name: PcanView.exe
You can download the PEAK drivers and software from the official PEAK website or use the drivers and software included in the following packages.
PEAK Software.rar

  1. Tools for Debugging:

  • PEAK Data cable connection

Step Three: Wiring and Parameter Modification

3.1 Electrical Connection

The wiring is done according to the motor schematic diagram of the actual project.

3.2 Parameter Modification Procedure

  1. Connection Peak

Connect the PEAK device to the F2A drive, taking note of the distinction between CANH and CANL. The meaning of these terms is:

  1. Launch the PcanViewe.exe software.

  • Configure the baud rate to 250K.

  • After clicking OK, I can read the data above in PCAN-view.

  1. Launch Curtis Integrated ToolKit

  • Must be loaded first: CurtisF2A. The corresponding firmware program can fully unlock the internal parameters: F2A.

  • Select Communication and click Connect.

  • Select Node 0x26 and wait for device load to complete.

  • Click Programmer.

3.3 Attention Items

Notice:

  1. Always verify that the connections to PEAKCANH,CANL, andF2Aare correct before connecting.

  2. For Cortez's softwareCurtis Integrated ToolKit, the company only has one authorized computer. Other engineers must purchase software authorization to debug on other computers.

Four, Drive Configuration

4.1 F2A Drive Working Mode

We utilize the Curtis-F2A Series of drives for implementation with the F2A. The velocity pattern is optimized for performance.

Note:
F2AThere is a problem with the position mode. When stopping, the walking motor will hold current, which will cause abnormal walking data feedback and motor aging.

Some problems you may encounter when using servo mode:

  1. When lifting the load fork (vehicle walking in a static state), there may be abnormal speed feedback on the walking motor, causing the alarm "out of path". In serious cases, it may cause lost positioning, which is dangerous during delivery.

  2. The walking motor has holding current. If it is blocked or stopped abruptly when starting multiple times, the F2A current cannot be attenuated and the F2A driver will report an error.

4.2 F2A Internal Parameters Requiring Modification

  1. Speed Mode Express - Improved speed mode

  • KP should be set to 30%. If the walking wheel does not appear to shake, it can be adjusted to 40%.

  • KI should be set to 40%.

  • Brake Rate should be set to 0.1 seconds.

  1. Speed Mode - Response - Fine Tuning

  • Max Speed Acceleration set to 0.1 seconds;

  • Max Speed Deceleration set to 0.1 seconds;

  1. Restraint - Position Hold

  • Soft Stop Speed should be set to 0 RPM;

  • Position Hold Enable should be set to ON;

  • KP should be set to 50%;

  • Kd should be set to 15%;

  1. Application Setup - EM Brake Control

  • Zero Speed Threshold should be set to 70rpm.

  • Brake Set Time should be set to 304ms.

  • Torque Release Time should be set to 200ms -- 100ms or even 50ms if the overshoot is bad;

  • Brake Release Time should be set to 48ms;

  1. Parameters related to descending proportional valve

  • Driver_1_Ki set to 2.5%.

  • Driver_1_Kp set to 25%.

  • Driver_1_Max_Current set to 0.8.

  • Driver_1_Min_Current set to 0.
