Overview

Specifications

• Number of Channels: 4 independent channels, each programmable independently.
• Resolution: 24-bit resolution per channel.
• Counting Frequency:Input Type: Differential (RS-422) or single-ended (TTL/CMOS).
  • General counting mode: DC to 10 MHz.
  • Quadrature counting mode: DC to 1.2 MHz (higher in X1 and X2 modes).
• Prescaler: Programmable to X1, X2, or X4.
• Interrupt Capability: Supports borrow interrupts and match interrupts.

Product Features

• Flexible Input Configuration: Supports RS-422 differential input and TTL single-ended input, with programmable polarity.
• Dynamic Reading Capability: A 24-bit output latch enables accurate dynamic reading of quadrature position values.
• Interrupt Function: Each channel is equipped with a 24-bit capture/match register, which can be used for hardware capture or interrupt generation.
• Low-Power Design: Full CMOS design ensures low power consumption.
• Scalability: Each VME slot can support up to 16 counter channels.

Structure and Composition

• Input Circuit: Includes an RS-422 differential receiver and a detachable termination resistor network.
• Counter Module: Each channel contains a 24-bit up/down counter, a preset/compare register, and an output latch.
• Interrupt Logic: Supports multiple interrupt conditions, such as borrow interrupts and match interrupts.
• Interface Logic: Interfaces with the host system to enable data transmission and control.

Application Fields

• Industrial Automation: Used for measuring and monitoring physical quantities such as rotation angle and displacement.
• Motion Control: Enables precise position and speed control in equipment like robots and CNC machine tools.
• Process Control: Controls equipment such as valves and pumps in fields like chemical engineering and pharmaceuticals.
• Building Automation: Controls systems such as lighting and HVAC (Heating, Ventilation, and Air Conditioning).
• Transportation Systems: Used for controlling equipment like traffic lights and elevators.

Installation and Maintenance

Installation

1. Ensure the input signal type (RS-422 or TTL) matches the configuration.
2. Adjust the termination resistor network as needed.
3. Configure the channel’s counting mode, polarity, and interrupt settings via software.

Maintenance

1. Regularly check input connections to ensure stable signal transmission.
2. Clean the equipment to prevent dust from affecting performance.
3. Update firmware and software to ensure system compatibility and security.
