Output voltage value:
● S 12-bit code(R12O ～ R01O,F36 ～ F37) (R12O2 ～ R01O2,F236 ～ F237) output:
Through the gear shift treatment, NC computes the spindle speed for every gear stage, that is, S 12-bit
code signal R12O
～
R01O(0~4095),R12O2
～
R01O2(0~4095)outputs to spindle frequency converter and
PLC. The relationship between 10V voltage and S 12-bit code is as follow:

input signal(spindle motor speed instruction signalR12I ～ R01I,R12I2 ～ R01I2), appointed by PLC, is used
to identify the 1

nd
spindle speed instructions decided by SIND/SIND2signal(G33.7/G35.7). When
spindle speed outputted by PLC is chosen, then spindle speed instructions are set by 12-bit code input
signal.
● voltage offset:
After spindle speed instruction S 12-bit code (0~4095) gotten, data parameterNO.3730 (voltage
compensate value when analog voltage output is 10V) and data parameterNO.3730 (voltage compensate
value when analog voltage output is 0V) can be used to finally compensate and clamp adjustment to
spindle speed instructions. The formula is as follows; take the 1st spindle for example:

036 . 021 . 9999

● Stop outputting conditions:
When S0 instruction is used, instructions output to spindle are all reset to 0. At this situation, none of
M05, emergency or CNC reset can make spindle speed output instruction of NC reset to 0.
