APO-05 Enc Pulse Sel : Sets the encoder output pulse direction. Forward operation in case of No. 0 (A+B) and reverse
operation in case of No. 2 –(A+B) are selected. No. 1 is selected for use as the frequency setting reference.
APO-06 Enc Pulse Num : Inputs the output pulse number per rotation.
APO-08 Enc Monitor : Convert encoder output in terms of motor revolution and displays it in terms of Hz and rpm.
BAS-20 Auto Tuning : Forward operation is carried out to 20Hz if you set the encoder related items described above and
set auto tuning at No. 3 Enc Test. After forward operation, it decelerates and accelerates back to 20Hz in the reverse
direction. In case of a failure of the encoder, the auto tuning item changes into None. In case of encoder misconnection,
Enc reversed is displayed. In such a case, change APO-05 Enc Pulse Sel or change 2 lines of the inverter output lines
connected to the motor with each other.

You can enhance the speed control precision of the V/F controller by mounting the encoder option card. Check the
encoder connection status before operation starts.
DRV-09 Control Mode : Sets the control mode at No. 2 V/F PG. Operation is carried out with the speed controller added
to No. 0 V/F control mode. The reference of the speed controller is the set frequency and the feedback is the encoder input.
