(Encoder Pulses per Revolution, PPR)
T
his parameter sets the pulses per
revolution (per channel) the drive receives
from the encoder. Set this value to agree
with the pulses per revolution on the
encoder nameplate if the tachometer is
directly coupled to the motor shaft. If
tachometer connected to rider roll to
measure linear velocity, then this should
be a calculated value equal to the counts
expected from the encoder when the
motor makes exactly one revolution.
