1.2. SPA description and explanation
Mounting the spindle position display (SPA) is by docking hollow shaft onto spindle shaft (max.14 mm in
diameter).The hollow shaft is fixed to the spindle shaft by hexagon screw and secured by power grip.
This way, the SPA is mounted in an overhung position and secured against torsion by torque support provided at
rear of the housing. The SPA features an absolute multiturn sensing system capable of detecting the position
after several spindle turns even in powerless state. Position data will be retained even in case of power failure
(min. 10 years).
The current position value is indicated in the two-line backlit LCD display (2x 5 digits, numeric), optionally
together with the target transmitted by the control (master). Two arrows indicate the editing engineer the
direction the spindle must be turned to for aligning actual value with target. As soon as actual value is in
alignment with target and within the permitted tolerances, the target will disappear. By corresponding master
parameterization the display can be turned by 180° enabling vertical respectively horizontal installation. SPAs are
networked by M8 connector, power supply is by the same cable directly from master. SPA parameterization by
master only.
