7.1.2 Data setting
Data setting related to speed control
Setting item Function code Setting Range, Setting Contents
Orientation speed setting (Note 1) P015
0.00∼99.99 / 100.0∼120.0 (Hz)
Orientation direction setting (Note 2) P016 0:Forward / 1:Reverse
(Note 1) : In order to stop the motor for setting position. (Motor takes 2 rotation to stop setting
position)Don’t set high frequency to the orientation speed setting. Otherwise it will be
over-voltage protection trip.
(Note 2) : Turn direction of the motor while orientation is done based on the setting of P016.

Completion range setting P017
0∼9999. / 1000 (10,000) (pulses)

Completion delay time (Note 4) P018
0.00∼9.99
Position loop gain(Note 5) P023
0.00∼99.99 / 100.0 (rad/s)
(Note 3) : The orientation stop position is to be set as 4096 of division (0∼4095) per 1 turn toward
forward from the original point. (It is 4096 division irrespective of the pulse number of
the encoder.) The original point is where the pulse has input to EZP-EZN. Stoppage
goal position is like shown in Figure 7-2 irrespective of the turn direction.
(Note 4) : It depends on what type of main body combines with the SJ-FB, the setting value
conversion is different. Please refer to the (Note 3) of the “5.3 Items regarding the feed
back board of the inverter main body“.
(Note 5) : To improve the positioning accuracy.à Increase position loop gain (G).
When the motor is unstable. à Decrease position loop gain.
