Operation Adjustment
Settings
Use the following settings if the gain adjustment in the basic settings does not
produce stable operation.
Limit Output during
Acceleration and
Constant Speed
Limit Output during
Deceleration and When
Stopped
Setting Description Set value Default Application Refresh timing
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

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. Use/Do

Setting Description Set value Default Application Refresh timing
Limit output during
deceleration and
when stopped 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. Use/Do
