Precautions
• The maximum input frequency of turning the inputs ON and OFF is shown below:
• When the DSPD instruction is used, the UP/DOWN pulse input, preset input and enable input operate in accordance with
the contents set by the parameters of the high-speed counter.
• When the measurement time is changed while the DSPD instruction is executed, the changed time is applied every time
the measurement time ends.
• When the current value of the high-speed counter is overwritten, a preset input is executed, or the high-speed counter is
reset by the DHCMOV instruction while the SPD instruction is executed, the operation continues, but the pulse density
cannot be measured normally.
• When the DSPD instruction is used, pulses per unit time which exceeds the ring length of the high-speed counter cannot be
input.
• The measurement time specified by (s2) overwrites the value stored in the SD device specified for the measurement unit
time.
• When the measurement time specified by (s2) is outside the range from 1 to 2147483647, the specified measurement time
is rounded into “1” with the sign.
