Mitsubishi MELSEC-A series User Manual

3. SPECWICATIONS /MELSEC-A
Error compensation is valid for: manual pulser inching, jogging and
positioning applications.
Backlash compensation, Bc, should be set according to the following
expression:
Bc=BxE
where, B = Actual backlash
E = As above
(1 0) Manual pulser inching travel increment
0 Defines the distance travelled each time a manual pulser inching
command is given.
0 The AD71 counts the number of manual pulser inching com-
mands input and transmits the appropriate number of output
pulses. (The speed is fixed at 2oooO PLS/sec.)
0 During manual pulser inching there is no automatic acceleration/
deceleration.
(1 1 ) Acceleration and deceleration times
0 Defines the period of time from the start of positioning to
when the speed limit value specified in the parameter is reached.
(Refer to Fig. 3.5.)

The acceleration and deceleration times cannot be set indepen-
dently.
Acceleration and deceleration are controlled at a constant
value.
When the positioning speed is very much lower than the para-
meter speed limit, the acceleration/deceleration time is com-
paratively short.
Acceleration/deceleration time is valid for zeroing, positioning,
and jog operations.
For interpolation positioning, the acceleration/deceleration
time for the axis with the longer travel is valid. (The acceleration/
deceleration time for the other axis is ignored.)
