Fagor handwheels: HBA, HBE and LGB
7.15 Fagor handwheels: HBA, HBE and LGB
Fagor handwheels HBA, HBE and LGB have:
• a pulse generator (encoder).
• an emergency output.
• One or two enable buttons.
• An axis selector switch.
• A resolution selector switch.
The encoder signals must be taken to the specific connectors of the CNC.
The signals from the 24V HBA and HBE models may also be taken to the PLC digital inputs located
at the central unit (not remote).
In the example on the left, the handwheel signals are taken to the feedback input (connector). Set
the corresponding general parameter AXIS , for example: AXIS4(P3)=11.
In the example on the right, the handwheel signals are taken to the digital PLC input. Set general
parameters HANDWIN (P111) = 65 and HANDWHE1 (P112) = 11.
The emergency button must be used in the safety chain of the electrical cabinet.
The HBE handwheel has one contact and the HBA and LGB models have a dual safety contact.
The enable push button (or buttons), the axis selector and resolution selector switches are always
handled by the PLC.
