Backlash countermeasures
What is the Backlash compensation?
Reduction gears have an engagement gap and have a dead zone between forward rotation and
reverse rotation. This dead zone is called backlash, and this gap disables the mechanical system
from following motor rotation.
More specifically, a motor shaft develops excessive torque when the direction of rotation changes
or when constant-speed operation shifts to deceleration, resulting in a sudden motor current
increase or regenerative status.
To avoid backlash, temporarily stop the acceleration/deceleration. Set the acceleration/deceleration
stopping frequency and time in P.229 to P.233.
Note: When setting up backlash compensation, acceleration /deceleration time only in part time longer.
