High-speed Counter/Pulse Output Instructions
Section 3-21
Description
PRV2(883) converts the pulse frequency input from high-speed counter 0,
according to the conversion method specified in C1 and the pulses/revolution
coefficient specified in C2, and outputs the result to D and D+1.
Select one of the following conversion methods by setting C1 to 0000 hex or
0001 hex.
Converting Frequency to Rotation Speed (C1 = 0
@
*
0 hex)
If C1 is 0
@
*
0 hex, PRV2(883) calculates the rotation speed (r/min) from the
frequency data and pulses/revolution setting. The second digit of C (
@
) speci-
fies the units and the third digit (
*
) specifies the frequency calculation method.
1.
Rotation Speed Units
• Rotation Speed Units = r/min
When the second digit of C (
@
) is 0, PRV2(883) calculates the rotation
speed in r/min from the frequency data and pulses/revolution setting.
Rotation speed (r/min) = (Frequency
÷
Pulses/revolution)
×
60
• Rotation Speed Units = r/s (CJM1 CPU Unit Ver. 3.0 or later only)
When the second digit of C (
@
) is 1, PRV2(883) calculates the rotation
speed in r/s from the frequency data and pulses/revolution setting.
Rotation speed (r/s) = Frequency
÷
Pulses/revolution
• Rotation Speed Units = r/h (CJM1 CPU Unit Ver. 3.0 or later only)
When the second digit of C (
@
) is 2, PRV2(883) calculates the rotation
speed in r/h from the frequency data and pulses/revolution setting.
Rotation speed (r/h) = (Frequency
÷
Pulses/revolution)
