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
PREF: 98.01
Default: FALSE
Range: FALSE / TRUE
Inverts the sense of the motor thermistor input. The default FALSE is normally-closed/low impedance.
INVERT ENC TRIP
PREF: 98.02
Default: FALSE
Range: FALSE / TRUE
Inverts the sense of the encoder fail input on the encoder Technology Box.
EXT TRIP MODE
PREF: 98.08
Default: DISABLED
Range: See below
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
PREF: 98.03
Default: FALSE
Range: FALSE / TRUE
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.
