Example for HHU on Sin.840d / Sin.810d V2.2
Functionality:
This example is based on modified standard blocks for the communication with the machine
control panel (MCP)
FC119(FC19) for standard MCP FC124(FC24) for the narrow MCP
Display on the HHU:
example: HHU acitvated: HHU deactivated:
Chan Name AUTO HHU not active
geoX –12345.678<mm Version_2.2
The first line shows the name and the associated mode-group of the selected channel.
The name and the actual position of the selected axis is displayed in the second line, as well as
the unit “mm/deg” and the positive/negative motion command („<“ or „>“).
The position will be displayed depending on the MMC-selection, in Workpiece-co-ordinate-
system(WCS) or machine-co-ordinate-system(MCS).
The unit will be “in/deg” and the position value will be displayed with 4 digits after the decimal
point for inch-systems.
HHU operation:
Via HHU you can select the modes: AUTO, JOG, INC1..INC1000; however, the modes MDA,
REF, IncVar and Inc10000 will only be displayed.
It is possible to select the channel (with multi-channel applications) and the associated geometry-
or channel(machine)-axis.
The 1
st
hand wheel is activated for the selected axis in the INC-mode.
Correlation with the MCP:
The MCP-push-buttons (except: Reset, NC-start/stop, SBL and the user-keys) are inactive when
the HHU is switched on.

Activation of HHU:
The HHU is activated via the the key-switch (turn right).
Selection of INC-mode / activation of hand wheel:
Use the push button “INC/handw.” In order to select and toggle through the incremental sub-
modes INC1..INC1000 whenever you are in JOG (or in AUTO/MDA with active FD/FDA);
deselecting via JOG or AUTO push button.
The incremental sub modes are displayed on the HHU as: 10,0 / 1,00 / 0,10 / 0,01 / ,001 / I[.]
INC10000 and INC-Var are only displayed (select via MCP when HHU is inactive)
The 1
st
-hand-wheel will be activated for the selected axis (deselected for all other axis); optional
a hand wheel selection via MMC is possible when the HHU is inactive (FC68 Parameter
HW_to_mmc = true).
note:
the maximum increment for the hand wheel can be limited via the machine data
"HANDWH_MAX_INCR_SIZE".
