The range of the ramp-up time S

value is out of range, the PLC processes it as the minimum or maximum output value. The ramp-up time and

ramp-down time are affected by the scan time. If you require accurate ramp-up or ramp-down time, it is

recommended that you use an output instruction with specified ramp up or ramp down time such as the DDRVI

instruction (API 2706).

The range of the target output frequency S

the PLC processes it as the minimum or maximum output value. A positive number for the output frequency

indicates forward output. A negative number for the output frequency indicates reverse output.

allows only Y0.0–Y0.11 for the output point. For the auxiliary output point specified by D

points in the following table. If you choose other output points or the M device, the value in SR indicating the output

mode is invalid and the Pulse+direction mode is valid by default. D

selects the even output point number.
