The cable fault LED light will can be falsely tripped to red, even when the cable connection is verified to be correct, if the load impedance of the encoder is too high.
When your HS35IQ encoder detects an acceleration outside of the normal range, the coupling slip fault LED with change to red. You can avoid this occurrence by reducing the acceleration/ deceleration of the motor. For support on a custom configuration file, contact Dynapar technical support.
If faults are disabled, the HS35IQ with PulseIQ Technology will continue to show a green LED rather than red. To ensure faults are not disabled, check the Fault Monitoring tab. Faults should be enabled to be notified for specific faults.
If the DLL file is missing, the PulseIQ Software will not be able to connect or open successfully. Ensure that you have Windows 8 or higher and Dtp-ToolBox.dll is placed in the same folder as the Service Tool .exe file.
If you experience trouble connecting your driver to PulseIQ Software, the driver may not be installed properly or the connection could be lose. Download and install the proper drivers for your OS at https://ftdichip.com/drivers/vcp-drivers/. Also, check all connections and ensure everything is plugged in properly.
Couplings also allow the encoder to compensate for shaft misalignment. Cutouts on the coupling allow flex to occur in the coupling rather than in the motor shaft. The runout from the shaft is absorbed by the coupling to prevent physical damage to the encoder.
Encoder tethers are designed and engineered to allow the encoder to float with the run-out of the motor shaft. If the tether is bolted too rigidly to the motor, then run-out from the motor can damage the encoder bearings. It is critical to use the parts provided with the encoder during installation to ensure the tether is properly placed. Avoid bending the tether from the position in which it is provided from the factory.
Without a functional tether, the wobble from the motor shaft will create additional wear on encoder bearings causing them to fail. Friction from bearing failure will cause encoder electronics to overheat.
