Backlash Compensation

There may be a certain amount of mechanical play present in gears, that will
affect positioning accuracy when the direction of positioning actions changes.
You can compensate for this by using backlash compensation.

There is only one parameter that needs to be set to compensate for back-
lash:

Backlash Compensation

DM m+4

Set to between 0000 and 9999 pulses.

Backlash

When the feeding direction is reversed, the number of pulses set in the DM
area is output at the initial speed, and the Position Control Unit then pro-
ceeds with normal operations.

Time

Compensation

If STOP is executed during backlash compensation for any operations requir-
ing acceleration or deceleration (HIGH-SPEED JOG, ORIGIN SEARCH,
ORIGIN RETURN, and START), the Position Control Unit will stop feeding
immediately after outputting the initial step of the acceleration or decelera-
tion, which will include the backlash compensation set above.
