Use the following settings if the gain adjustment in the basic settings does not
produce stable operation.

Number of
Encoder Pulses
for One Motor
Revolution
Calculate the number of encoder pulses for
one motor revolution from the encoder res-
olution (pulses/revolution), high-speed
counter’s multiplier, and motor-encoder
shaft gear ratio. For example, if the
encoder resolution is 1,000, the high-
speed counter multiplier is 4, and the gear
ratio is 1/4, the number of encoder pulses
for one motor revolution is 1,000 × 4 × (1/4)
= 1,000.
0 to 65,535 0 This setting is
used when con-
verting the out-
put value to an
inverter fre-
quency com-
mand.

Setting Description Set value Default Application Refresh timing
Limit output during
acceleration and
constant speed
Select this option to limit the upper and
lower values of the output value based on
the pulse output value during internal
pulse output acceleration or constant
speed.

Select this option to multiply the error of
the output value by a coefficient during
internal pulse output deceleration or
after output has been completed.
