6 Application of Encoder (PG)
The maximum frequency of the encoder (PG) output pulses that can be detected is 300 kHz.
To find the output frequency of your encoder (PG), use the following formula.
Maximum power available to drive the encoder (PG) with the PG-X2 is 200 mA. Should
your encoder (PG) require more than 200 mA, it will be necessary to provide a separate
power supply. If momentary power loss ride-through function is necessary, provide backup
capacitor or take other necessary measures. See Fig. 7.
