Working Principle

The module receives differential pulse signals from an incremental encoder and processes them through internal counting circuits. It supports 1x, 2x, and 4x pulse multiplication to improve position resolution. The internal counter accumulates pulse counts to calculate current position, and measures pulse frequency to derive speed values. It transmits position and speed data to the main controller via serial communication, and supports hardware trigger signals for precise position latching.

Installation Requirements

• Install in a standard industrial control rack with proper backplane connection
• Use shielded twisted-pair encoder cables with proper grounding
• Keep encoder cables away from high-voltage power lines and motor cables
• Ensure encoder supply voltage matches the module’s output specification
• Mount the module in a vibration-damped location for reliable operation
• Maintain adequate clearance for wiring and heat dissipation

Usage Notes

• Encoder cable length must not exceed the maximum rated distance
• Shielding must be connected only at one end to avoid ground loops
• Do not exceed the maximum input pulse frequency
• Set counting parameters correctly according to encoder specifications
• Regularly inspect encoder connections for wear and looseness
• Perform periodic calibration of position measurement accuracy
