Control functions |
Servo lock/unlock | Creates (Servo lock) or releases (Servo unlock) the position loop on the PCU. |
Position control | Positions to an absolute position or relative position according to the target position and target speed specified from the ladder program. |
|
Origin determination |
Origin search: Establishes the origin using the specified search method. Present position preset: Changes the present position to a specified position to establish the origin. Origin return: Returns the axis from any position to the established origin. Absolute encoder origin: Establishes the origin using a Servomotor that has an absolute encoder, without having to use an origin search. |
|
Jogging | Outputs pulses at a fixed speed in the forward rotation or reverse rotation direction. |
|
Interrupt feeding | Performs positioning by moving the axis a fixed amount when an external interrupt input is received while the axis is moving. |
|
Speed control | Performs speed control by sending a command to the Servo Drive speed loop. | |
Torque control | Performs torque control by sending a command to the Servo Drive current loop. | |
Stop functions | Deceleration stop: Decelerates the moving axis to a stop. Emergency stop: Positions the moving axis for the number of pulses remaining in the deviation counter and then stops the axis. |
|
Auxiliary functions |
Acceleration/ deceleration curves |
Sets one of the following: a trapezoidal (linear) curve, an exponential curve, or an S-curve (moving average). |
Torque limit | Restricts the output torque during axis operation. | |
Override | Multiplies the axis command speed by a specified ratio. Override: 0.01% to 327.67% |
|
Servo parameter transfer |
Reads and writes the Servo Drive parameters from the ladder program in the CPU Unit. |
|
Monitoring function |
Monitors the control status of the Servo Drive, such as the command coordinate positions, feedback position, current speed, and torque. |
|
Software limits | Limits software operation within the positioning range during position control. | |
Backlash compensation |
Compensates for the amount of play in the mechanical system according to a set value. |
|
Deviation counter reset |
The position deviation in the Servo Drive’s deviation counter can be reset to 0 (unit version 1.3 or later). |
|
External I/O |
Position Control Unit |
One MECHATROLINK-II interface port |
Servo Drive I/O | Forward/reverse rotation limit inputs, origin proximity inputs, external interrupt inputs 1 to 3 (can be used as external origin inputs) |
|
Self-diagnostic functions | Watchdog, flash memory check, memory corruption check | |
Error detection functions | Overtravel, Servo Drive alarm detection, CPU error, MECHATROLINK communications error, Unit setting error |
