Operation
Note 2. These parameters become effective when the power is turned ON again after having been
turned OFF. (Check to see that the LED display has gone OFF.)
Note 3. With the default setting (G1/G2 = 4), the Servomotor will rotate once when the encoder resolu-
tion pulses are input.
Note 4. One position deviation (deviation counter) display and positioning completed range pulse
make one input pulse. (This is called a command unit.)

D Servomotor with 2,048 (Pulses/Rotation) Encoder
• When set to G1/G2 = 8192/1000, the operation is the same as for a 1,000-pulses/rotation Servomotor.

H Functions
• Perform soft start processing for the command pulses using the selected filter to gently accelerate and
decelerate.
• Select the filter characteristics using Pn207.0 (position command filter selection).
• When Pn204 (position command filter time constant 1) is selected, acceleration and deceleration are
performed using the primary filter (exponentiation function).
• When Pn208 (position command filter time constant 2) is selected, acceleration and deceleration are
linear.
• This function is effective in the following cases:
There is no acceleration/deceleration function in the command pulse (controller).
The command pulse frequency changes rapidly, causing the machinery to vibrate during accelera-
tion and deceleration.
The electronic gear setting is high (G1/G2 = ≥ 10).
