3.1 Hardware disposition

The articulated motor uses the CAN communication mode and has two communication cables. It is connected to the debugger through the can to USB tool. The debugger needs to be installed with the ch340 driver in advance and works in AT mode by default.

It should be noted that we are based on the specific can to USB tool development of the debugger, so we need to use our recommended serial port tool to debug the debugger, if you want to transplant to other debugger platform can refer to the third chapter of the instructions for development.

The CAN to USB tool is recommended to use the official USB-to-CAN module of RobStride. The frame header of the corresponding serial port protocol is 4154, and the frame tail is 0D 0A.

When using the CAN-to-USB module, pay attention to the settings of the DIP switches on the module: When DIP switch 1 is in the ON position, the module enters Boot mode and cannot establish a connection with the host computer. When DIP switch 2 is in the ON position, a 120Ω terminal resistor is connected to the module port, allowing normal communication with the host computer.

4.2 Motor Function Description

(If the following features are unavailable, please upgrade to the latest version via the official Git repository.)

4.2.1 Active Reporting

• Disabled by default. Enable via Type 24.
• Report type: Type 2 (default interval: 10ms). Adjust interval by modifying EPScan_time via Type 18.

4.2.2 Zero-Point Flag (zero_sta)

• Modify via:
• Host computer (software)
• Type 18 (requires saving via Type 22 for communication)
• Default flag: 0 → Power-on position range: 0–2π.
• If set to 1: Power-on position range: π–π.

4.2.3 Type 2 Update

• Updated to periodic looping within -4π–4π (enables cycle counting).
• Note: Position interface parameters must be adjusted:
• P_MIN: -12.57f
• P_MAX: 12.57f

4.2.4 Protocol Switching (Requires CAN adapter)

• Methods:
• Modify protocol_1 via host computer.
• Send Type 25 command.
• Reboot required after switching.
• Post-switch CAN commands:
• CANopen: Send extended frame (protocol switch frame).
• MIT Protocol: Send standard frame (Command 8).

4.2.5 Post-Power-Off Anti-Backdrive Protection

• Default: Motor imposes damping if rotated rapidly while poweredoff (prevents surge).
• Disable: Set damper = 1.

4.2.6 Zero Calibration Rules

• Supported modes: CSP and Motion Control.
• PP Mode: Zero calibration is blocked.
• Old vs. New Versions:
• Old: Zero calibration causes large deviation → motor immediately moves to target
• New (CSP/Motion Control): Target updates to 0 instantly →motor remains stationary.

4.2.7 Position Offset (add_offset)

• Example: If offset = 1, the current zero shifts to (current position +1rad).
• Use case: Bypass mechanical limits (e.g., set zero at 1 rad →power-on treats 1 rad as new zero).

4.2.8 CANopen ID

• Old version: Fixed to 1.
• New version: Matches the private protocol CAN ID.

Notes for Implementation

• Always save settings (e.g., Type 22 for zero_sta).
• Verify CAN adapter compatibility for protocol switching.
• For zero offsets, ensure mechanical safety limits are respected.

4.3 Control mode instructions

4.3.1 Operation control mode

The motor is in operation control mode by default after power-on.

Send motor Enable Run frame (communication type 3) --> Send operation mode motor control command (communication type 1) --> Receive motor feedback frame (communication type 2)

Operation control mode description: The control logic of the operation and control mode is t_ref=Kd * (v_vset-v_actual)+Kp * (p_set-p_actual)+t_ff. Tref is converted to the expected iq current through an internal formula and output through the current loop Simple control demonstration: Set t_ff to 0, v_vset to1, Kd to 1, p_set to 0, Kp to 0. If there is no external load on the motor, it will run at a speed of 1rad/s. If there is an external load, kd needs to be increased to resist the external load Set t_ff to 0, v_vset to 0, Kd to 1, p_set to 0, Kp to 0, the motor is in damping mode. When the motor is externally rotated, a damping is applied, which increases with the increase of kd. It should be noted that the motor generates electricity under this condition and requires power supply to prevent overvoltage Set t_ff to 0, v_vset to 0, Kd to 1, p_set to5, Kp to 1. If there is no external load on the motor, it will run to the target position of 5. Increasing kp will increase the force required to maintain the target position, and kd is damping. Without kd, the motor will sway to the target position

4.3.2 Current mode

Send motor mode parameter write command (communication type 18) Set the runmode parameter to 3 --> Send motor Enable run frame (communication type 3) --> Send motor mode parameter write command (communication type 18) set the iq_ref parameter to the default current instruction

5. Explanation of Canopen Communication Protocol Types

5.1 Introduction to CANopen Communication

CANopen is a "higher-level protocol" based on the CAN bus. This means that theCAN bus (ISO 11898) acts like a container truck, serving as the "transportation vehicle" for CANopen information. CAN simply implements the transmission of frames with an 11-bit CAN ID, a Remote Transmission (RTR) bit, and 64 data bits(related to higher-level protocols). The CAN bus plays the same role in CANopen as it does in the J1939 protocol. CANopen implements Layer 7 of the OSI model and is compatible with other data link layer protocols besides CAN.Please download the necessary EDS files for CANopen from the official website download center at www.robstride.com.

5.2 Canopen Protocol Message Classification

5.3 State Machine Description

Motor Enable:

When initially powered on, the motor defaults to the SWITCH_ON_DISABLED state. To transition to OPERATION_ENABLE, modify the Controlword(6040H) to 6, 7, or 15 (step-by-step transition), or directly set it to 15 for immediate enablement.

Stopping the Motor:

If the motor is in OPERATION_ENABLE state and needs to stop normally, modify the Controlword (6040H) to 1. The motor will return to the disabled state (SWITCH_ON_DISABLED).

Emergency Stop (Use with Caution—Risk of Voltage Surge):

During operation, an emergency stop can be triggered by setting the Controlword (6040H) to 11.

Fault Clearance:

If the motor enters a FAULT state due to protection mechanisms, modifying the Controlword (6040H) can clear standard errors.

Important Note:

Mode changes for this motor must be performed in the disabled state (SWITCH_ON_DISABLED). Ensure the desired mode is configured before enabling OPERATION_ENABLE to avoid unexpected behavior.

5.4 Status Feedback Parameters

5.5 Homing Mode (Zero Position Setting)

Homing method:

• Set Modes of operation to 6 while the motor is in the disabled state (SWITCH_ON_DISABLED). The motor will then define the current position as the zero point.
• To hold the zero position, modify the Controlword to 15, and the motor will maintain its position at the home location.

5.6 Position Mode (PP - Profile Position)

Steps to Configure Position Mode (PP):

1. While the motor is in the disabled state (SWITCH_ON_DISABLED), set Modes of operation to 1.
1. Mandatory parameters:
1. Target_torque (absolute max torque in position mode)
2. Profile_velocity (absolute speed in position mode)
3. Profile_acceleration (absolute acceleration in position mode)
2. Optional parameters:

2. Position_window_time (if not set, window check is disabled)
2. Set Controlword (6040) to 15 to enable operation.
3. Set Target_position (absolute position) to move the motor to the desired position.

5.7 Position Mode (CSP - Cyclic Synchronous Position)

Steps to Configure Position Mode (CSP):

1. While the motor is in the disabled state (SWITCH_ON_DISABLED), set Modes of operation to 5.
1. Mandatory parameters:
1. Target_torque (absolute max torque in position mode)
2. Profile_velocity (absolute speed in position mode)
2. Optional parameters:
1. Position_window (0 = disabled)
2. Position_window_time (0 = disabled)
2. Set Controlword (6040) to 15 to enable operation.
3. Set Target_position (absolute position) to move the motor to the desired position.

5.8 Velocity Mode

Steps to Configure Velocity Mode:

1. While the motor is in the disabled state (SWITCH_ON_DISABLED), set Modes of operation to 3.
1. Mandatory parameter:
1. Target_torque (absolute max torque in velocity mode)
2. Set Controlword (6040) to 15 to enable operation.
3. Set Target_velocity to reach the desired speed.

5.9 Torque Mode

Steps to Configure Torque Mode:

1. While the motor is in the disabled state (SWITCH_ON_DISABLED), set Modes of operation to 4.
2. Set Controlword (6040) to 15 to enable operation.
3. Set Target_torque to output the desired torque.
