Parameter Descriptions
INPUT 2 BREAK
A general purpose signal designed to be internally wired to the function block ANALOG INPUT 4, 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 DISABLED WORD parameter).
This parameter is not saved in the Drive's non-volatile memory and thus is reset to the default setting at power-up.
THERMISTOR
The current state of the motor thermistor trip input, modified by INVERT THERMIST input.
ENCODER
The current state of the encoder feedback card (Option F) error trip input. TRUE is tripped.
EXTERNAL TRIP
If external trip mode is set to Coast or Trip then this shows the state of the latched trip caused by external trip, (digital input
5). If the external trip mode is set to Disabled, this output will be
STO ACTIVE
Indicates if the STO (Safe Torque Off) circuit is active: i.e., STO prevents the drive from running.
This parameter is available in firmware version 3.9 and greater.
COMMS BREAK
Setting this parameter to True causes the COMMS BREAK trip.
Functional Description
The I/O TRIPS function block allows trips to be generated by signals on the input terminals of the Drive. Refer to Chapter 11
for a description of the trips supported by the Drive.
