Command Editor: The Command Editor is a primary tool for actuator control, command configuration, and motion status display. It allows users to control the movement of the electric actuator, including backward and forward movements, initialization, error resets, and servo toggling. Users can import and export point configurations between controllers.
Status Bar: Displays real-time data such as position, velocity, torque, and force of the electric actuator. It helps in monitoring the actuator's movement and making necessary adjustments.
Command Items: Includes features like Backward/Forward for fine-tuning, Stop to halt movements, Initialize for setting up post-power on, Reset Error for clearing alarms, and Save/Load commands to/from the controller.
Command Types: Detailed explanations of command types such as Absolute Move, Relative Move, Push, and Precision Push are provided. Each command type has specific parameters like position, velocity, acceleration, and force, which need to be configured according to the actuator's requirements.
Absolute Move Command: Moves the actuator to a set position using the origin as a reference. Parameters include position, velocity, acceleration, and deceleration.
Relative Move Command: Moves the actuator to a set position using the current position as a reference. Similar parameters as Absolute Move are used.
Push Command: Starts movement from the current position with a rated output force until the set force is reached. It is crucial for adaptive gripping in electric grippers.
Precision Push Command: Similar to Push but focuses on maintaining an exact force value. It is used for precision force control type actuators.
Example Usage: An example of using the Absolute Move command for adjusting an electric gripper's position is provided, detailing the steps and parameter settings required.
Command Editing Examples:
  • Rapid Positioning: The document provides examples of using the [Absolute Move] and [Relative Move] commands to adjust the position of the RM-GB-11-20 gripper. For [Absolute Move], the position is set to 0mm, velocity to 80mm/s, acceleration/deceleration to 500mm/s², and band to 0.1mm. For [Relative Move], the distance is adjusted based on the current and target positions, with similar settings for velocity and acceleration.
  • Rapid Flexible Pushing and Pressing: This section describes using a combination of [Absolute Move] and [Push] commands to grip a workpiece. The [Absolute Move] command is used to position the gripper close to the workpiece, and the [Push] command applies additional force to ensure a secure grip.
Offline Data Collection Interface:
  • Data Collection Settings: The interface allows for real-time data collection, including current position, output, and force. Data can be exported to Excel for analysis.
  • Data Collection Commands: Commands include [Start Current Collect], [Start Persistence Collect], and [Execute Command and Collect], which gather data during specific command executions.
Status Monitor Interface:
  • Left Side Status Bar: Displays the current action execution status of the motor, indicating whether commands like [Absolute Move] or [Push] have been completed successfully.
  • Right Side Status Bar: Shows the status of external I/O inputs and outputs, useful for troubleshooting I/O control issues.
Parameter Editor Interface:
  • Change Station Number & Baudrate: Users can modify the controller's station address and baudrate settings via the Modbus RTU connection.
  • Change MAC Address: Each device on the bus requires a unique MAC address, which can be set through the Parameter Editor.
  • Change IP Address: For Modbus TCP communication, the controller's IP address can be changed similarly.
  • External I/O Input and Output Configuration: Users can configure I/O mappings within the controller to match their specific needs.
Pulse Parameter Adjustment: To configure pulse parameters, connect the software using Modbus RTU. In the Command Editor, enable parameters [planner.pulse_control] and [planner.pulse_mode]. The default pulse unit is 1mm per pulse, adjustable as needed. Save changes to the controller and restart for them to take effect.
Power-Up Home Position Setting: The actuator defaults to returning to the home position on power-up. To enable or disable this, connect via Modbus RTU, search for 'auto' in the Parameter Editor, and adjust [cmd_manager.auto_start_command_index] to '34' to enable or '-1' to disable. Save changes and restart.
Home Position Direction Reversal: To reverse the home position direction, connect via Modbus RTU, search for 'logic' in the Parameter Editor, and change [driver.logic_dir] between '1' and '-1'. Save changes and restart.
I/O Mapping Interface: Use the I/O Mapping interface for configuring I/O input and output. Connect input and output parameters via the interface for customization. Changes synchronize with external I/O configurations.
Modbus RTU Communication Guide: Modbus RTU is used for controlling electric grippers and modifying parameters. Function codes like 02H, 03H, 04H, and 05H are used for reading input statuses, holding registers, input registers, and forcing single coils, respectively. Each function code has specific addresses and data types for various operations like reading alarms, setting positions, and executing commands.
Modbus Communication Message Example: Modbus RTU messages consist of a device address, function code, data field, and checksum. An example message '01 04 00 00 00 02 71 CB' reads the current position from a device with address 1 using function code 04.
Overview: This document is a technical guide on Modbus RTU communication, focusing on reading and writing data to slave stations, particularly for controlling electric actuators. It covers various function codes and their applications in reading positions, velocities, torques, and setting parameters.
1. Reading Data:
  • Current Position/Velocity/Torque: Use function code 03 to read holding registers. Example: Reading current torque from address 2154.
  • Alarm Signals: Use function code 02 to read input status, such as current alarm status from address 0.
2. Writing Data:
  • Positioning Parameters: Use function code 10 for writing multiple registers. Example: Writing a floating-point number requires conversion to hexadecimal and endian conversion.
  • Trigger Actions: Use function code 05 to force a coil, such as triggering an error reset.
3. Positioning Mode:
  • Introduction: Requires parameters like distance, acceleration, and velocity before writing the target position.
  • Execution: Actions are triggered based on differential detection of written values versus current values.
  • Example: Setting parameters for "Absolute Move" and "Pressing Motion" with specific velocity, acceleration, and torque values.
4. Precautions and FAQs:
  • Data Types: Ensure correct data types to avoid improper parsing.
  • Position Verification: Compare current and target positions with a deviation of ±0.1mm and velocity below 2mm/s.
  • Torque Mode: Judgments based on position deviation and velocity thresholds.
  • Safety Factor: Affects torque percentage to prevent damage.
  • Interruption Handling: Optimization measures for command interruptions.
Interrupt Handling:
1. Initialize Interrupt: When interrupted by an Initialize command, wait for the completion signal, then update the position register with the current actuator position.
2. Stop or Servo Toggle Interrupt: Introduce a 15-30ms delay for stability, then update the position register with the current actuator position.
Maintenance Guidelines:
1. General Principles: Apply WD-40 lubricant if the actuator hasn't been used for over half a month, especially in winter.
2. First Time Use: Use WD-40 on unused travel ranges.
3. Long Term Non-use: Use WD-40 only in specific situations; for regular maintenance, use NSL grease.
4. Maintenance Frequency: Regular checks and grease replenishment are recommended at specified intervals (1 month, 6 months, 1 year, and every half year thereafter).
