4.
Set the type of pressure feedback control to use in Pn458 = n.
X
(Pressure Feedback Type
Selection).
5.
Set the Torque Control Gravity Compensation Switch (Pn440 = n.X
) according to the
system.
For a vertical axis or other axis that is affected by gravity, enable gravity compensation (Pn440 =
n.1
).
For a horizontal axis, disable gravity compensation (Pn440 = n.0
).
To ensure safety during setup, the default value is set low. Use a monitor function or other means
to confirm the motor speed and set a suitable value.

CAUTION
If you enable gravity compensation (Pn440 = n.1
) and the pressure feedback detection
value is 0 when the pressure sensor is faulty, pressure feedback control will not be performed
normally and the Servomotor will be operated with excessive torque, possibly damaging the
workpiece or machine.
Set Pn447 (Pressure Feedback Loop Deviation Overflow Level), Pn402/Pn403 (Torque Limits),
and Pn483/Pn484 (Force Limits) to suitable values.

n.1
Enable gravity compensation.
For gravity compensation, input the pressure sensor output to the SERVOPACK and monitor the
pressure feedback detection value. If you do not connect a pressure sensor and disable pressure
feedback control (Pn440 = n.
0), always disable gravity compensation (Pn440 = n.0
).
