CNC 8055 I CONFIGURATION
SOFT: V02.2X
CNC structure
Protection at the connectors
It detects over-currents or short-circuits at the +5 V of the feedback of the handwheels, spindle and
probe and it issues the relevant error message.
Besides this, it also detects the 24V of the external supply at the digital outputs.
Hardware protections
The axis board installed in the CNC includes the recognition of the 24V at the inputs and outputs.
Signal adapters
The following signal adapters are available to be used with the feedback inputs.
SA-TTL-TTLD Adapter for "Non-differential TTL" to "differential TTL" signals
SA-FS-P Adapter for Fagor sinusoidal signal to Vpp signal.
