RTD The system has the capability of displaying real-time feedback from an optional RTD (Resistance
Temperature Detector) module. Up to 16 RTD channels can be monitored. The warning and trip
level (in degrees Celsius) can be set individually for each RTD channel. Setting the trip level to
zero for any channel indicates that no RTD is connected, and the value will not be displayed.
Digital Output 0 from the RTD Module must be wired to one of the digital inputs of the drive as an
enable signal in order for the Drive to respond to RTD trips.

Configured as a Run Enable will stop the motor according to the programmed Stop Mode
whenever an RTD Trip occurs.

Configured as a Drive Enable will cause the Drive to coast to a stop whenever an RTD Trip
occurs, regardless of Stop Mode setting.
Digital Output 1 of the RTD module indicates when any RTD temperature is above the WARNING
level, and may be interfaced to customer control logic.
Digital Output 2 of the RTD module indicates when any RTD temperature is above the TRIP level,
and may be interfaced to customer control logic.
NOTE : If no RTD module is connected, the warning and trip levels can still be adjusted. This can
cause the HMI to display an RTD trip, but it will have no effect on the operation of the Drive.
