Servo motion feedback instructions and driver control servo motor movement commands mainly involve multiple aspects.
These instructions and commands enable the servo system to accurately control the movement of the motor and realize functions such as positioning and speed control.
The following is a detailed summary of these instructions and commands:
Servo motion feedback instructions
Servo motion feedback instructions are mainly used to read the status information of the servo system for monitoring and adjustment. Common servo motion feedback instructions include:
1. Position information reading instructions:
POS: used to read the actual position information of the servo motor.
CMD_POS: used to read the command position, that is, the target position information.
2. Speed information reading instructions:
VEL: used to read the actual speed information of the servo motor.
CMD_VEL: used to read the command speed, that is, the target speed information.
3. Torque information reading instructions:
TORQ: used to read the actual torque information of the servo motor.
CMD_TORQ: used to read the command torque, that is, the target torque information.
Driver control servo motor movement commands
Drive control servo motor movement commands are mainly used to control the start, stop, speed, position, etc. of the servo motor. These commands include, but are not limited to:
1. Start and stop commands:
START or equivalent start command: starts the servo motor moving.
STOP, ABORT and EMERGENCY_STOP: are used to stop the servo motor normally, forcibly and urgently, respectively.
2. Position control commands:
ABS: absolute position control command, which moves the servo motor to a specified absolute position.
INC: incremental position control command, which moves the servo motor a certain amount relative to the current position.
-Specific PLC instructions, such as P0, P1, etc. (may vary for different PLC brands and models), are used to set the target position of the servo motor.
3. Speed control commands:
VEL: sets the maximum speed of the servo motor.
ACCL and DECEL: set the acceleration and deceleration of the servo motor, respectively, to achieve a smooth acceleration and deceleration process.
JERK: sets the smoothness of the speed to reduce the impact when the acceleration changes.
4. Torque control commands:
TORQ_LIMIT: sets the maximum torque value of the servo motor.
TORQ_GAIN: Adjust the torque gain coefficient of the servo drive.
5. Other control commands:
HOME and INDEX: Calibration commands used to calibrate the position of the servo motor to the origin or specified position.
DDRVI and DDRVA: Relative and absolute position drive instructions commonly used in PLC, used to control the servo motor to move to the specified relative or absolute position.
Notes
- Different servo drive brands and models may have different instruction sets and command formats, so it is necessary to refer to the specific servo drive manual or technical documentation in actual applications.
- When writing the control program, it is necessary to ensure the accuracy and rationality of the instructions to avoid abnormalities or damage to the servo motor caused by instruction errors.
- The commissioning and maintenance of the servo system requires professional technicians to ensure the stable operation and efficient operation of the system.
In summary, the servo motion feedback instructions and the commands for the driver to control the movement of the servo motor are important components of the servo system, and they together realize the precise control of the servo motor.
