Output Off / Fault Condition
The controller LED will tun On solid to signal that the output stage is off as a result of a any
of the recoverable conditions listed below.
•
Over temperature
•
Over Voltage
•
Under Voltage
•
“Dead man” switch activation (See “Using the Inputs to turn Off/On the Power
MOSFET transistors” on page 50.
The controller will resume the normal flashing pattern when the fault condition disappears.
A rapid continuously flashing pattern indicates that the controller’s output is Off and will
remain off until reset or power is cycled. Activating the emergency stop will cause the con-
troller to stop in this manner. A permanent error will also be triggered if the encoder mod-
ule is mounted and an encoder error is detected. Note that while the controller is Off, it will
continue to respond to commands if in the RS232 mode, and can thus be reset by sending
the %rrrrrr command.
