20 Positioning Control – FNC150 to FNC159
20.7 FNC158 – DRVI / Drive to Increment
S2 :When using a special high-speed output adapter for the pulse output destination in an FX3U PLC, the rotation
direction signal must be used by the following table output.
When using a built-in transistor output for the pulse output destination in an FX
3G/FX3U/FX3GC/FX3UC PLCs, the
rotation direction signal must use transistor output.
S3:"D.b" is available only in FX3U and FX3UC PLCs. However, index modifiers (V and Z) are not available.
S4 : This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
Caution on writing during RUN
During RUN, avoid writing while DRVI (FNC158) instruction is executed (that is, while pulses are output).
Note that if writing is executed during RUN to a circuit block including FNC158 instruction while pulses are output, the
PLC decelerates and stops pulse output.
