2087 Preload of each axis (Tcmd offset)
[Data type] Word axis
[Unit of data] (Preamplifier limit) /7282
[Valid data range] –1821 to 1821
An offset is added to a torque command to reduce backlash.
Set a slightly large value than that of the friction torque of the motor.
As a reference set a value one–third the rated torque.
[Example] To set a torque of 3A in the opposing directions for the master and slave
amplifiers that have current limit of 40A:
3 / (40 / 7282) = 546
Master side = 546
Slave side = –546
2021 Load inertia
[Data type] Word axis
Set the same value to the master and slave axes.
[Unit of data] (All load inertia)
2
2022 Direction of rotation of motor
[Data type] Word axis
Set the direction of motor rotation.
If the rotation directions of master and slave axes are opposite, set them
by this parameter.
