Digital Output 1
Zero Speed Detected
The operating level of this output can be modified
by the standstill zero threshold parameter to give
the desired accuracy of operation
+24V at zero speed YES B5
Digital Output 2
Drive Healthy (Drive Operational)
This output is true when the controller is Healthy.
+24V when Healthy YES B6
Digital Output 3
Drive Ready
This output is true when the controller is ready to
function, i.e., “locked” into the mains.
+24V when Ready YES B7
Program Stop Input
Program Stop
When the Program Stop input is held at +24V,
the drive operates as required by the inputs.
When the Program Stop is open circuit or at zero
volts, the controller provides a controlled or
program stop as defined by the Program Stop
parameters.
+24V drive run
0V (o/c) drive program stop
Threshold +16V
NO B8
Coast Stop Input
Coast Stop
When the Coast Stop input is at +24V, the
controller operates normally. When the Coast
Stop is at zero volts or open circuit, the main
contactor is open and the drive no longer
operates. The motor coasts to rest.
+24V drive run
0V (o/c) drive coasts to rest.
Threshold +16V
NO B9
