Positioner errors are used to trigger consequences on the system, for instance
disable, emergency break, etc. Positioner hardware status information is mainly
provided for information purposes.
Positioner hardware status description:
General inhibition detected: This refers to the General Inhibition connector at the rear
panel or the Stop All button at the front panel of the XPS controller. The General
Inhibiton connector is a safety feature and can be used for a custom STOP ALL
emergency switch. Inhibition (pin#2), must always be connected to GND during normal
operation of the controller. In this case, inhibition is not detected. An open circuit is
equivalent to pressing STOP ALL on the front panel, in which case, inhibition is
detected.
ZM high level: This refers to the mechanical zero signal used with some stages. The ZM
signal is high during one part of the travel and low during the other part of the travel.
The detection of the ZM high/low transition in combination with an encoder index pulse
signal allows a fast and repeatable origin search
(MechanicalZeroAndIndexHomeSearch).
Minus end of run activated: Refers to the hardware minus end of run limit switch.
During normal operation, this end of run switch should never be activated and any
motion will be stopped by the detection of the minus software limit.
Plus end of run activated: Refers to the hardware positive end of run limit switch.
During normal operation, this end of run switch should never be activated and any
motion will be stopped by the detection of the positive software limit.
