690+ Series Frequency Inverter
I/O TRIPS
This function block is designed to operate in
conjunction with the Analog and Digital
Input function blocks to trip the Inverter on a
loss of setpoint input or safety control input.
Functional Description
The I/O TRIPS function block allows trips to be generated by signals on the input terminals of
the Inverter. Refer to the Installation Product Manual, Chapter 6 for a description of the trips
supported by the Inverter.

Parameter Descriptions
INVERT THERMIST
Range: FALSE / TRUE
Inverts the sense of the motor thermistor input. The default FALSE is normally-closed/low
impedance.
INVERT ENC TRIP
Range: FALSE / TRUE
Inverts the sense of the encoder fail input on the encoder Technology Box. FALSE for
normally-closed.
EXT TRIP MODE
Range: TRIP /COAST
When set to TRIP, DIN8 (EXT TRIP) will trip the drive when +24V is not present, causing
EXTERNAL TRIP to be displayed on the MMI.
When set to COAST the drive will not trip, but “coasts to stop” when +24V is not present.
INPUT 1 BREAK
Range: FALSE / TRUE
A general purpose signal designed to be internally wired to the function block ANALOG
INPUT 1, BREAK parameter. When this signal goes TRUE this causes an INPUT 1 BREAK
trip to occur, (unless this trip is disabled within the TRIPS STATUS function block, see the
DISABLE TRIPS parameter).
This parameter is not saved in the Inverter’s non-volatile memory and thus is reset to the
default setting at power-up.
INPUT 2 BREAK
Range: FALSE / TRUE
A general purpose signal designed to be internally wired to the function block ANALOG
INPUT 2, BREAK parameter. When this signal goes TRUE this causes an INPUT 2 BREAK
trip to occur, (unless this trip is disabled within the TRIPS STATUS function block, see the
DISABLE TRIPS parameter).
This parameter is not saved in the Inverter’s non-volatile memory and thus is reset to the
default setting at power-up.
THERMISTOR
Range: FALSE / TRUE
The current state of the motor thermistor trip input, modified by INVERT THERMIST input.
ENCODER
Range: FALSE / TRUE
The current state of the encoder Technology Box error trip input. TRUE is tripped.
EXTERNAL TRIP
Range: FALSE / TRUE
The current state of the External Trip input (terminal 19). Note that this input is inverted, so is
TRUE if 0V is on the terminal.
