Connecting the
wireless handwheel
system
A wireless handwheel system is always connected to the control via the M23
plug connection of the HRA 551FS. The advantage of this is that the wireless
handwheel system is also supplied with power via this connection so that no
additional supply lines must be provided.
The serial communication, dual-channel emergency stop and dual-channel
permissive buttons of the HR 550FS mobile part are routed from the
HRA 551FS (M23 plug connection with handwheel cable, ID 296467-xx) via
the corresponding handwheel adapter, ID 749368-xx, to the control hardware.
For this purpose, special, short handwheel cables (ID 296467-xx) in lengths of
1.0 m, 1.5 m and 2.0 m were introduced. The reason for this is the charging
current required for the HR 550FS mobile part. Due to the small cross section
of the handwheel cable it can be transmitted only over short distances. This
means that longer cables with ID 296467-xx cannot be used for the wireless
handwheel system. If longer handwheel cables are required, HEIDENHAIN
should be consulted. A maximum distance of 50 m between X23 (MC 4xx or
MB 620/PLB 6001 for HSCI) and the HRA 551FS base station can be attained
by using the adapter cable ID 749368-xx and the optional extension cable ID
749369-xx (with a handwheel cable, ID 296467-xx, with a length of max.
2.0 m).
Please note that the new adapter cables, ID 749368-xx, and extension cables,
ID 749369-xx, will not be available until April 2011. Until then, the wireless
handwheel system must be connected with the currently available cables,
which limits the attainable cable length to the base station to 22 m!
