(numerator)
Servomotor will rotate once (i.e., the internal driver
will rotate x 4). (See note 1.)
Note 1. Set within the range 0.01 G1/G2 100.
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.)

pulse factor
(Pn217)
Note 1. If the PSEL (command pulse factor switching) input is ON when Pn218.0 (command pulse
factor switching selection) is set to 1, the result from multiplying the set value in Pn217 (com-
mand pulse factor) is multiplied again by the electronic gear ratio.
Note 2. Command pulse factor switching is a new function supported by Servo Drivers with software
version “r.0037.”

• Perform soft start processing for the command pulses using the selected filter to gently accelerate and
decelerate.
