PRECAUTIONS AND PARAMETER SETTING FOR
HANDHELD BOX
The handheld box and additional panel share the interface XS7, and thus they can use only one
function at the same time. Select the handheld box or additional panel through system parameter 86: if
parameter 86 = 0, the handheld box is selected; if parameter 86 = 1, the additional panel is selected.
The output signals of handheld box and additional panel have corresponding diagnosis signals on the
controller, as in the figure below
13.11.5
TROUBLESHOOTING FOR HANDHELD BOX
When any fault occurs, please set the operation mode to MDI, press the Diagnosis key to enter the
diagnosis interface, and press the Up/Down key to switch to handheld box test interface, as in the
figure above. Then, rotate and press the corresponding switch, and the corresponding diagnosis signal
changes; otherwise, this signal has fault. Please check the connection of the signal wire and the switch.
If normal, the input interface of the controller has internal fault. Please contact the manufacturer.
When the handwheel is rotating, the counter shows the received pulses, and HNDA and HNDB
signals change alternatively. If there is no counting, and HNDA and HNDB signals have no change,
please check the wire connection and whether the 5V power supply of the handwheel is normal. If the
connection is normal, but the handwheel doesn’t have 5V power supply, the internal power supply of
the controller has fault. Please contact the system manufacturer. Note: the 5V power supply is only for
the handwheel.
