DECELERATION TIME
The parameter deceleration time is the same value as the acceleration time. Deceleration time refers to the time
from the speed limit value to a stopped state, so it becomes proportionally shorter as the setting speed
decreases.
DECELERATION RATIO
A ratio used when the machine is decelerated using a toothed gear. This ratio is a numeral larger than 1.
CURRENT VALUE This is the current address (position) when stopped or during positioning.
CURRENT VALUE CHANGING
The LD75 has no way of knowing the current value when the machine is assembled and the positioning module
is connected, so this function is used to teach it a temporary approximate value as the current value. This
function can also be used to write a temporary current value when the current value has been lost due to
accidents, etc. If an OPR is carried out after that, the positioning module will recognize the zero point.
To prevent the accumulated value from exceeding the stroke limit in fixed-feed, etc., rewrite the current value to 0
after the fixed-feed. The current value can be changed during a positioning stop.
ERROR CORRECTION
If a dimension error occurs in the machine, and that error is actually smaller or larger than 1m (3.28feet) in spite
of a 1m (3.28feet) command being issued from the LD75, that error amount will be compensated. For example,
when the error is actually smaller than 1m (3.28feet), the remaining distance to 1m (3.28feet) is fed, and the
correct 1m (3.28feet) of positioning is carried out.
FAST OPR
The axis returns to the machine OP at the OPR speed without detecting the near-point dog.
(This is not validated unless a machine OPR has been carried out first.)
COMPOSITE SPEED
The movement speed for the target control during interpolation operations.
