XBF-PD02A

Description

Two-axis positioning module for the XGB family, supports position and speed control with linear and circular interpolation, accepts pulse command control. Designed for compact, PLC-integrated motion tasks.

The Polar Energy Assessment:

The PD02A is a 2-axis positioning expansion module providing motion functions including position control, speed control, combined x/speed modes, and linear/circular interpolation for two axes. It stores step sequences (vendors note up to 150 step entries per axis), supports pulse based command units, and integrates with XGB CPUs and the platform’s parameter settings for step changes, homing, and multi-step profiles. This is a straight, PLC-native positioning unit for OEM machines that need simple multi-axis motion without a full servo controller.

Pros

• Two axes with linear and circular interpolation, useful for small gantry and labeling tasks.
• Multiple control modes including position and speed control, and stored step sequences per axis.
• Integrates with XGB toolchain and parameter settings for quick deployment.

Limitations

• Not a full multi-servo motion controller, limited to pulse/step style control and the module’s built-in limits.
• Requires reading the manual for step table programming and axis parameter limits, OEMs should validate step counts for complex moves.

Typical use cases

• Compact gantry control, indexing tables, feeders, labelers, and simple pick-and-place where two coordinated axes are sufficient.
