362 HEIDENHAIN Technical Manual iTNC 530 HSCI
The TE keyboard units are supplied with power via the USB port (USB type B).
USB cables that are connected to the USB ports of the TE keyboard units must
be fixed with the corresponding cable tie (strain relief) to protect the USB
connectors from mechanical load.
Possible configurations for the potentiometers of a TE 6xx
The override potentiometers of a TE 6xx can be configured in machine
parameter MP7620 bit 5 and bit 9. If bit 5 is set in MP7620, the potentiometers
are evaluated as feed-rate and rapid-traverse override potentiometers. If an
HSCI TE keyboard unit with three override potentiometers (spindle, rapid
traverse and feed rate) is used, bit 9 must be set in MP7620. If bit 5 and bit 9
are both set at the same time, an error message is triggered due to invalid
configuration.
For the evaluation of the potentiometers, the following distinctions are made
between HSCI and non-HSCI hardware:
TE for systems without HSCI
Configuration with feed-rate and rapid-traverse overrides (MP7620, bit 5).
The spindle-speed override is used as rapid-traverse override. The NC keys
are used to realize the spindle speed override. If hardware for systems
without HSCI is used, bit 9 is ignored.
TE for systems without HSCI
Configuration for three potentiometers with feed-rate, spindle-speed and
rapid-traverse overrides (MP7620, bit 5). This configuration has no effect.
The potentiometers are evaluated, as usual, as feed-rate and spindle-speed
overrides. Bit 9 is ignored.
