2.6: Protection
2.6.1: Safe Torque Off & Motor Torque Off
The XE2, XP2, and XM2 models have the Safe Torque Off (STO) function. Two inputs are provided
which, when de-energized, prevent the upper and lower devices in the PWM outputs from being
operated by the digital control core. This provides a positive OFF capability that cannot be overridden
by the control firmware, or associated hardware components. When both inputs are energized, the
control core will be able to control the on/off state of the PWM outputs. The STO feature in these
models was developed in accordance with several functional safety standards and has both SIL and
Category/Performance Level ratings. For more information on STO for the Xenus Plus Dual Axis
models, see the
Xenus Plus Dual-Axis STO Manual
The XEL, XPL, and XML models have the Motor Torque Off (MTO) feature. The MTO circuit in these
models was designed using guidance from IEC 61800-5-2.
It operates in the same way as STO but does not have the certifications of STO..
2.6.2: Faults
Overview
Xenus Plus detects and responds to a set of conditions regarded as faults, such as drive over
temperature and excessive following error. When any fault occurs, with the exception of a following
error, the drive’s PWM output stage is disabled, the fault type is recorded in the drive’s internal
error log (which can be viewed with CME), and the status LED changes to indicate a fault condition
exists. A digital output can also be programmed to activate on a fault condition. The following error
fault behaves with slight differences, as described in
Following Error Fault Details (p.53)
The drive’s PWM output stage can be re-enabled after the fault condition is corrected and the drive
faults are cleared. The process for clearing faults varies depending on whether the fault is
configured as non-latched or latched. The fault-clearing descriptions below apply to all faults
except for the following error fault, which is described in
Following Error Fault Details (p.53)
Clearing Non-Latched Faults
The drive clears a non-latched fault, without operator intervention, when the fault condition is
corrected.
DANGER
Risk of unexpected motion with non-latched faults.
After the cause of a non-latched fault is corrected, the drive re-enables the PWM
output stage without operator intervention. In this case, motion may re-start
unexpectedly. Configure faults as latched unless a specific situation calls for non-
latched behavior. When using non-latched faults, be sure to safeguard against
unexpected motion.
Failure to heed this warning can cause equipment damage, injury, or death.
