4 Explanation of Interface Signals
4.4 PLC Output Signals (Data Type: R***)
[Caution]
(1) Be sure to turn ON the "Speed monitor mode" signal (SOMD) after confirming deceleration of all axes.
If the "Speed monitor mode" signal (SOMD) is turned ON without deceleration, and the motor rotation speed exceeds
the set speed, a speed monitor alarm will occur, resulting in an emergency stop state. Then, power of the drive sec-
tion will be shut off.
(2) Turn OFF the "Speed monitor mode" signal after confirming the door lock is OFF.
(3) Even if the "Speed monitor mode" signal (SOMD) is turned ON while parameter error is output, speed monitoring is
not initiated. Set the parameter with appropriate value, and then turn ON the "Speed monitor mode" signal (SOMD).
(4) While the axis is being removed, it will be taken off from the watch list even if the parameters "#2313 SV113/bitF"
(safety observation function) and "#13229 SP229/bitF" are ON. However, the emergency stop will occurs when axis
detachment is performed for all axes in the group which the door state signal is turned ON with "#2282 SV082/bitF-C"
(Digital signal input selection) and "#13227 SP227/bitF-C" (Digital signal input selection). Do not remove the axis
which the door state signal is to be input.

Cont. Signal name
A Handy terminal Data area top address
[Function]
The top address of the area that stores the data to be transmitted to and received from the handy terminal is set.
[Operation]
Set the R register top address on the CNC side corresponding to D0 on the handy terminal side to the "Handy terminal
Data area top address" (R297), and set the number of registers required for communication to the "Handy terminal Data
valid number of registers" (R298).
<Setting example>
The following is the setting value used for allocating the data from R9800 to R9849, the CNC side user area, by using 50
registers from D0 to D49 in the handy terminal side.
"9800 (0x2648)" for "Handy terminal Data area top address" (R297)
"50 (0x32)" for "Handy terminal Data valid number of registers" (R298)
