Description

The Allen-Bradley 1746-QS is a specialized motion control module engineered for the SLC 500 programmable logic controller platform. It is designed to provide high-performance Synchronized Axis Control, particularly for closed-loop servo positioning applications. This module is frequently deployed in demanding hydraulic systems where precise movement and synchronized timing across multiple axes are required for operational efficiency. The 1746-QS manages up to four independent or synchronized axes, delivering high-speed updates to maintain exact positioning even during high-velocity motion cycles.

Features

  • Supports control for up to 4 independent or synchronized axes.
  • High-speed 2 ms update time for drive outputs to ensure precise motion tracking.
  • Supports S-curve acceleration and deceleration profiles to minimize mechanical stress and prevent pressure spikes in hydraulic actuators.
  • Allows for dynamic adjustment of motion parameters while the axis is in active motion.
  • Compatible with Linear Displacement Transducers (LDTs) for accurate position feedback.

Applications

The 1746-QS is primarily utilized in industrial automation environments requiring sophisticated motion control, such as hydraulic presses, injection molding machines, material handling systems, and synchronized multi-axis positioning rigs within the SLC 500 ecosystem.

Installation Guidelines

  • Ensure the SLC 500 chassis is powered down before inserting or removing the 1746-QS module to prevent electrical damage.
  • The module should be installed in a slot within the SLC 500 rack; ensure the backplane connector is fully seated.
  • Use shielded cabling for LDT inputs and analog outputs to minimize electromagnetic interference (EMI) from high-voltage lines or variable frequency drives.
  • Maintain proper ventilation in the control cabinet to ensure the module operates within the specified 0 to 60 degC temperature range.
  • Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect sensitive internal circuitry.

FAQ

What type of feedback device does the 1746-QS support?

The module is designed to interface with Linear Displacement Transducers (LDTs) to provide real-time position feedback for the controlled axes.

Can the motion parameters be changed during operation?

Yes, the 1746-QS allows for the dynamic adjustment of motion parameters while the axis is in motion, facilitating flexible process control.

What is the primary power source for this module?

The module draws its power from the SLC 500 backplane, requiring 1.0 A at 5V DC and 0.200 A at 24V DC.
