15. Backlash compensation function
 SR478, SR479, SR498, SR499, SR518, SR519, SR538, SR539, SR558, SR559, SR578, SR579
For AS series, up to 12 high-speed outputs (Y0.0-Y0.11) can be set. Each output works with a corresponding SR
for users to set the output number for backlash compensations. The setting range is 0-32767. If the setting value is
<= 0, this function is disabled.
 This function is available for firmware version 1.02.30 and later. The output instrucitons that support odd number
axis outputs and are directional output by default are JOG, DZRN, DPLSV, DDRVI, DDRVA, DPPMR, DPPMA,
DCICR, DCICA, DCICCR, DCICCA, DCCMR, DCCMA, DPPGB and TPO. For even number axis outputs, you
can use the following instructions JOG, DPLSV, DDRVI and DDRVA. For firmware version 1.10 or later, CSFO
instruction is also supported.
 If the above-mentioned supported instructions are used and the instruction is stopped right after the output
directon is changed, if the backlash compensation function is enabled under this condition, PLC needs to run
the compensated ones before a real stop. So that there will be no uncompensated backlashes left when the
next output is enabled.
16. Flags to show the output number of the current positioning output in the ramp up / ramp down area.
(available for firmware V1.06.00 or later)
 SR652-653 (32-bit value)
The output number in the ramp up area: the accumulated output number counted from the acceleration starting
point to the target speed point (not included).
 SR654-655 (32-bit value)
The output number in the ramp down area: the accumulated output number counted from the target speed point
(not included) to the output stopping point.
17. Flags to show the CAN communication quality (available for firmware V1.06.00 or later)
 SR823
Hardware receiving error counter for CAN communication: when the error number exceeds 127, it indicates the
hardware error occurance is too frequent, you need to check the communication cables or adjust the
transmission speed or modify the sample points manually.
 SR824
Hardware sending error counter for CAN communication: when the error number exceeds 127, it indicates the
hardware error occurance is too frequent, you need to check the communication cables or adjust the
transmission speed or modify the sample points manually.
18. Ethernet IP related flags
 SM1000, SR1000~SR1015 and (SR1016, SR1536~SR1539 are available for firmware V1.06.00 or later)
SM/SR
SM1000 Ethernet setting flag.
SR1000
Ethernet IP address (32-bit)
SR1001
Function Action
ON: the values in SR1000–SR1006 are written into the flash
memory. After writing the values, the PLC resets it to OFF.
NOTE 1: do not set the flag to ON continuously to avoid
damage to the flash memory.
NOTE 2: the PLC must be in STOP state before writing the
values into the flash memory.
For example: 192.168.1.5, SR1000 is 16#C0A8 and SR1001
is 0105.
