AC890PX AC Drive
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.
INPUT 2 BREAK PREF: 98.04 Default: FALSE Range: FALSE / TRUE
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.
