Table 9-1: LED Indicators
To clear a fault, the enable input needs to be lowered, and then raised. Faults can
also be cleared by the PC software. Faults that result in a blinking red LED indicator,
are cleared automatically once the fault condition is no longer present.
9.2 Fault descriptions and Recovery
Faults are divided into Safety Faults and Critical Faults.
Safety Faults are configurable. If the fault is configured as a stop motion, the fault
will be cleared automatically once the fault condition is no longer present. If a safety
fault is enabled and configured for disable motor, the fault will be latched until it is
cleared in the same manner as the critical faults described at left.
All Critical Faults will disable the motor when they occur. To clear these faults, the
fault condition cannot be present and the enable input line must be lowered and
then raised to proceed with motion.
