Enabling Analog Commands
For safety reasons, the Analog command mode is disabled by default. To enable the Analog mode, use the PC
utility and set Analog in Command Priority 2 or 3 (leave Serial as priority 1). Note that by default the additional
securities are enabled and will prevent the motor from starting unless the potentiometer is centered, or if the
voltage is below 0.25V or above 4.75V. The drawing shows suggested assignment of Pot 1 to ANA1 and Pot 2 to
ANA4. Use the PC utility to enable and assign analog inputs.
USB communication
Use USB only for configuration, monitoring and troubleshooting. USB is not a reliable communication method
when used in a electrically noisy environments and communication will not always recover after it is lost without
unplugging and replugging the connector, or restarting the controller. Always prefer RS232 communication when
interfacing to a computer. USB and CAN can operate at the same time on the FDC3260. Plugging USB to a com-
puter will not disable the CAN interface.
Status LED Flashing Patterns
After the controller is powered on, the Power LED will tun on, indicating that the controller is On. The Status LED
will be flashing at a 2 seconds interval. The flashing pattern provides operating or exception status information.
Additional status information may be obtained by monitoring the controller with the PC utility.
