(d) A warning "Deceleration/stop speed change (warning code: 500)" occurs and the
speed cannot be changed in the following cases.
• During deceleration by a stop command
• During automatic deceleration during positioning control
(e) A warning "Speed limit value over (warning code: 501)" occurs and the speed is
controlled at the "[Pr.8] Speed limit value" when the value set in "[Pr.14] New speed
value" exceeds the "[Pr.8] Speed limit value".
(f) When the speed is changed during interpolation control, the required speed is set in
the reference axis.
(g) When carrying out consecutive speed changes, be sure there is an interval between
the speed changes of 100ms or more.
(If the interval between speed changes is short, the LD75 will not be able to track, and it may become
impossible to carry out commands correctly.)
(h) When a speed change is requested simultaneously for multiple axes, change the
speed one by one. Therefore, the start timing of speed change is different for each
axis.
(i) The speed cannot be changed to 0 during the machine OPR.
The speed change request is ignored.
(j) When deceleration is started by the speed change function, the deceleration start
flag does not turn ON.
