4.5.7 Home position return under position control (Pr.110, Pr.111, Pr.453, Pr.455, Pr.508,
Pr.509, Pr.532 to Pr.534)
Determine the home position for the position control. Position control with an absolute position cannot be performed
until the home position is set.

The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)

When a value exceeding 3000 r/min is set, the rotation speed will be limited at 3000 r/min.
Also, when an S-PM geared motor is used, the maximum setting value differs depending on the drive unit capacity. (0.2 to 2.2K: 12000 r/min, 3.7K: 8000
r/min)
(1) Home position return pattern selection (Pr.532)
 Use Pr.532 to set a pattern of home position return. The following operation is performed according to the control mode.
 To perform home position return, turn ON the start signal (STF signal or STR signal) without selecting a point table and
JOG operation (RH, RM, RL, and JOG are OFF).
 Home position return is started when the start signal (STF signal or STR signal) is turned ON (at the leading edge).
 For PM sensorless vector control, position detection is not performed by a sensor such as an encoder but by energizing
the motor. Thus, turning OFF the SON signal or the LX signal eliminates the home position. After turning ON the SON
signal (LX signal), always perform the home position return. In addition, when the power is turned OFF, the home position
is eliminated. After turning ON the power, always perform the home position return.
 Under speed control, home position return cannot be performed. To perform home position return, always select the
position control mode.

NOTE
 Turning OFF the power or the SON signal (LX signal) eliminates the home position. After turning ON the power or the
SON signal (LX signal), always perform the home position return. (For the roll feed, the home position return
operation is not required.)
