）
Signal symbol
：
EBUFg
（
G142.7
，
G154.7
，
G166.7
，
G178.7
）
Signal type ： PLC → NC
Signal function
：
command the CNC to read PLC axis controlling 1 block amount’s command
data.
（ 6 ） Axis control read completion signal （ PMC axis control ）
Signal symbol
：
EBSYg
（
F130.7
，
F133.7
，
F136.7
，
F139.7
）
Signal type ： NC → PLC
Signal function
：
CNC informs the PLC has read the PLC axis controlling one block amount’s
command data into the buffer signal.
（ 7 ） Reset signal
Signal symbol
：
ECLRg
（
G142.6
，
G154.6
，
G166.6
，
G178.6
）
Signal type
：
PLC → NC
Signal function ： when the system resets the PLC axis control command and the signal is set
to “1” :
A. when the axis moves: the axis decelerates to stop
B. when temporarily executing: stop execution
C. when the miscellaneous function is executed: when the execution is stop and the buffered
commands are cleared, the input control command is invalid while the signal is 1. When the
continuous feed command
（ EC0g ～ EC6g ： 06h ） is specified, the reset signal ECLRg is
set to 1
，
i.e., the command ends. This moment, the servo motor decelerates to stop, the
axis moving signal EGENg is set to 0 ， and the control axis selection status signal EAXSL is
also set to 0. Before the control axis selection status signal EAXSL is set to 0
，
the reset
signal ECLRg remains 1. Besides, before the axis moving signal EGENg is set to 0
，
the
reset signal ECLRg remains 1.

Block stop signal
Signal symbol
：
ESBKg
（
G142.3
，
G142.3
）
Signal type
：
PLC → NC block stops the invalid signal’s signal symbol: EMSBKg
（
G143.7
，
G167.7
）
Signal type ： PLC → NC
Signal function
：
stop each command block or forbid stop for each block. In the course of
executing the PLC sending commands, when the block stop signal ESBKg
is set to 1 and the current executing block ends, the system stops the axis
control. The block stop signal ESBKg is set 0, the system executes the
buffered command. But, when the block stop inhibit signal EMSBKg is set to
1
，
the block stop signal ESBKg is invalid.
