Forward Software Limit Flag and Reverse Software Limit Flag
Word b+1
Bits 12 and 13
Function These flags turn ON and OFF when the software limit function is enabled to
indicate the present position status for the forward/reverse software limit.
Forward Software Limit Flag
0: Within forward software limit range
1: Forward software limit range exceeded
Reverse Software Limit Flag
0: Within reverse software limit range
1: Reverse software limit range exceeded
Details Refer to 10-8 Software Limits .
4-8-5 External I/O Status Bits
The External I/O Status Bits (word b + 3) show the I/O status of the I/O signals
allocated to the Servo Drive.
b = Beginning word of Axis Operating Input Areas specified in Common

Bit 10 (Emergency stop input) indicates the status of the emergency stop
input signal input when using a G-series Servo Drive or SMARTSTEP Junior
Servo Drive. This bit is always 0 when using a W-series Servo Drive, which
does not have an emergency stop signal.
The SMARTSTEP Junior Servo Drive does not have inputs for external latch
signals 2 and 3. When using a SMARTSTEP Junior Servo Drive, the input sta-
tus for these signals will always be 0.

status Forward rotation limit input Returns the status of I/O signals
for each axis.
1: Signal valid
0: Signal invalid
The external I/O status shows the
enabled/disabled status of signals
used for PCU control.
This status is different from the
electrical ON/OFF status of the I/O
signals.
