Determining the Internal Pulse Output Frequency
Use the following formula to calculate the internal pulse frequency (Hz) to out-
put from the pulse output instruction (e.g., PLS2) based on the power supply
frequency (Hz) to be output from the inverter to the motor.
Note
(1) Calculate the power supply frequency for one revolution per second from
the motor specifications. For example, with a 1,800-r/min (60-Hz) motor
(30 r/s), the power supply frequency for one revolution per second would
be calculated as follows: 60 [Hz]
÷
30 [r/s] = 2 [Hz].

Lower 4
digits
When a present value is read, the following
data is stored in D and D+1 as an 8-digit hexa-
decimal value.
P = #0020/#0021: The actual movement from
the internal pulse origin.
P = #0030/#0031: The present value of the
error counter.
