July 2013 3.34 TE 645Q (FS) keyboard unit 363
TE for systems with HSCI
Configuration with feed-rate and rapid-traverse overrides (MP7620, bit 5).
The spindle-speed override input S (X52) on the rear of the TE is not
evaluated. The rapid-traverse override must be connected to the provided
connector E (X61, X62). There are no NC keys for spindle-speed override.
Machine operating panel keys must be used instead, and the function must
be realized in the PLC program (the PLC program must transmit the
information to W764).
The + , – and 100% keys for spindle-speed override can be snapped on to
an HSCI machine operating panel. Contrary to keyboards for systems
without HSCI, these keys are only available as PLC inputs, and not as NC
keys. They are not evaluated automatically by the NC software. The PLC
program must evaluate the keys and transmit the calculated value to the NC
in W764 (spindle-speed override). The NC software limits this value
depending on MP3310.0 (max. spindle-speed override value) and MP3310.1
(minimum spindle-speed override value).
TE with three potentiometers for systems with HSCI
Configuration for three potentiometers with feed-rate, spindle-speed and
rapid-traverse overrides (MP7620, bit 9): Feed-rate, spindle-speed and rapid-
traverse overrides are evaluated.
