Encoder Pulse Dividing Output - Mitsubishi Electric FR-A800 Series Instruction Manual

5.11.15 Encoder pulse dividing output

The encoder pulse signal at the motor end can be divided in division ratio set in the parameter and be output.
Use this parameter to make the response of the machine to be input slower, etc. The FR-A8AL or the FR-A8TP is required to
be installed.

*1 This parameter is available when the FR-A8AL (option) is installed.
*2 This parameter is available when the FR-A8TP (option) is installed.
• Division waveform by division ratio
Both ON-OFF width is division times (50% duty).
• Pulse waveform example at 1000 pulse input when Pr.413 or Pr.863 = "2"
NOTE
• Control of motor rotation (forward or reverse) by phase difference between A phase and B phase is as follows.
When A phase is 90° advanced as compared to B phase: Forward rotation
When A phase is 90° behind as compared to B phase: Reverse rotation
