Note 6. Tighten the screws to a tightening torque of 0.5 to 0.6 N
m. The terminal block may be dam-
aged if the tightening torque is too strong, and malfunctions and short-circuits may result if the
tightening torque is too weak.

•
The maximum response frequency is 30 kHz.
•
Taking into consideration the encoder pulse deviation (phase difference: 90
±
45
°
) and the waveform
when the cable is long, select a smaller number of pulses than the ones shown in the following table.

D
3G3FV-PPGD2/-PPGX2
•
The maximum response frequency is 300 kHz.
•
When the encoder pulse deviation (phase difference: 90
±
45
°
) is taken into consideration, the number
of encoder pulses can be calculated by means of the following formula:
Number of encoder pulses [p/r]
60 x maximum response frequency (300,000 Hz)
2 x motor’s maximum rotation speed (r/min)
x
•
If the motor’s maximum speed is less than 4,000 r/min, an encoder of 1,000 to 2,000 p/r is recom-
mended. Even if an encoder with higher than required resolution is selected, it will not improve the
speed control range or precision.
