I/O TRIPS
SETUP::TRIPS::I/O TRIPS
This function block is designed to operate in conjunction with the Analog and Digital Input function blocks to trip the Drive on
a loss of setpoint input or safety control input.
Parameter Descriptions
INVERT THERMIST
Inverts the sense of the motor thermistor input. The default FALSE is normally-closed/low impedance.
INVERT ENC TRIP
Inverts the sense of the encoder fail input on the encoder Technology Box.
EXT TRIP MODE
Determines the special function of digital input 5.
Enumerated Value : External Trip Mode
0 : TRIP - A low at digital input 5 will cause an external trip
1 : COAST - A low at digital input 5 will cause the motor to coast to stop. The drive will not trip.
2 : DISABLED - Digital input 5 does not have any special function.
INPUT 1 BREAK
A general purpose signal designed to be internally wired to the function block ANALOG INPUT 3, 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 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.
