As described in “Hardware connection,” the touch panel is connected to
the RS–232–C serial port 2 (JD36B) on the CNC motherboard. When the
touch panel is used, serial port 2 (JD36B) is set up for touch panel
operation, regardless of an I/O channel (input/output unit selection) set up
in parameter Nos. 20, 21, 22, and 23. Use JD36A for other input/output
units.
The existing settings of parameter Nos. 100, and 121 to 123 are disabled
for channel 2 (JD36B), and fixed as follows:
S Baud rate: 9600 bps
S Stop bit: 1 bit
S Parity check: None
If no touch panel is used, parameter DDS (bit 2 of parameter No. 3119)
must be set to 1.
Number Message Description
085 COMMUNICATION
ERROR
A communication error occurred during
touch panel initialization.
It is likely that the touch panel is not con-
nected correctly or is defective.
After correcting the cause of the error,
cycle the power.
This alarm message is used also for er-
rors in existing input/output units. If a
conventional input/output unit is con-
nected to RS–232C serial port 1
(JD36A), this alarm message may be
displayed because of an error on serial
port 1.
CAUTION
1 The touch panel soft keys cannot be used after memory
(SRAM) is cleared to all 0s. In this case, it is necessary to
use the MDI (cursor and page keys) for setup.
2 After the power is switched on, do not use the touch panel
until a power–on reset sequence is completed. Otherwise,
a P/S alarm (No. 085) indicating a communication error.
3 If more than one point on the touch panel is pressed
simultaneously, it is assumed that only one point that
represents a gravity position determined according to the
way each point is pressed, is pressed. Be sure to press only
one point at a time.
