Increase Uptime with Fault Indication

See exactly what is at fault so you can find root cause with confidence. No more guessing or replacing only to have the problem occur again.

• Insufficient Voltage: Sense supply voltage changes and low voltage conditions that are otherwise difficult to detect.
• Cable Integrity: Catch encoder cable ‘open’ faults such as cable breaks or loose conductors.
• Shaft Slip: Detect clamping collar slip, between the shaft and encoder physical connection, prior to coupling failure. 
• Overspeed: Detect shaft speed exceeding predetermined limit.
• Electronic Failure: Continuously monitor electronics which may result in irregular pulse output.
• Over-Temperature: Measure ambient temperature to provide early indication of operating condition changes.

See product datasheet to learn more about fault conditions, fault LED operation and potential corrective actions.

No More Guess Work Thanks to Recent Fault History

The HS35iQ encoder is an industry first to offer smart diagnostics with storage of recent faults. Connect a PC via dedicated USB fault output. Use PulseIQ™ Encoder Software to access:

• Recent events by time stamp and a description of specific faults triggered. 
• Device info including model number, build date and runtime.
• Current encoder configuration including resolution, index pulse position/gating, output phasing.

See product software manual section "PulseIQ™ Encoder Software Screens and Functionality" section 3, Event Log for more information

Troubleshoot Confidently with Visuals

No more trial and error. Quickly review fault conditions and diagnostic the problem without wasting time.

Visual indication of fault condition is provided by 4 fault status LEDs. Additional details and fault history can be viewed by connecting to the diagnostics port via USB cable and opening PulseIQ™ Encoder Software. Digital fault output is also provided via a dedicated output signal, which can be connected to a PLC. 

See an example of how to connect fault output to a PLC here.

Program Encoder Output to Match Your Needs

PulseIQ™ Technology allows the option to customize encoder specifications to meet your needs. Adjust encoder resolution, phase, index pulse output and more with PulseIQ™ Encoder Software. Simplify and consolidate inventory by stocking fewer encoder part numbers with programmable output.

• Programmable resolution up to 20,000 PPR (pulses per revolution)
• Set output phase direction A leads B from encoder clockwise or counter-clockwise
• Specify output voltage to TTL or HTL
• Determine Home Index (Z Pulse) position and gating and edit to current position via software
• See ordering information in datasheet for a full list of programmable features

Please note, programmable functionality is optional and dependent on part number ordered. Please see product datasheet for more details.

Easily Mount to Any Shaft

Hollow-shaft encoders can directly mount to motors or driven shafts without the need for couplings, flowerpots or matching flanges, eliminating additional components and points of failure.

The HS35iQ encoder offers comparable mounting options to our existing HS35R hollow-shaft encoder. Simply match the bore size to the desired motor or driven shaft size and install the encoder via a single point rod tether or slotted flexible tether. Use the included nylon washers to help protect the encoder from motor shaft currents.

See our installation manual to learn more about proper hollow-shaft encoder installation techniques.
