Figure A-6. Shutdown Input Circuit Configuration
The Shutdown input circuit forms a filter that introduces an approximate 1mS delay, which
reduces the chances of false triggering of the Shutdown input.
Fault Ouputs
The individual Fault 1, 2 & 3 outputs indicate an over-current fault has occurred on a
particular axis (1, 2 or 3). The Fault output can be reset by toggling (turning OFF and ON)
the axis Shutdown input. If a supply rail fault occurs, all three axes Fault outputs will signal a
fault. In this situation you may either reset each individual axis or cycle the power to the
drive to clear the fault indication.
Composite Fault Output
This output is used to alert a controller that a fault has occurred on one or more axes of the
drive.
Zero Phase Outputs
The individual Zero Phase outputs 1, 2 & 3 indicate the zero phase condition for each
individual axis, that occurs once every electrical cycle or 50 times per mechanical revolution
of the motor.
LED Indicators Function
The bi-coloured LED indicates the state of the drive, as shown in Table A-4.
