Overlapped Command Of Operation Modes; Small Travel - Mitsubishi Electric FX2N-10PG User Manual

Model FX2N-10PG Pulse Output Block
8.1.3

Overlapped command of operation modes

Positioning operations are not started even if START is input or START command (BFM#26 b9)
is turned ON when plural operation patterns are selected with BFM#27, or the manual pulse
generator input operation is selected (plural bits are on). (The error code K6 or K7 is written in
BFM#37.)
The positioning operation is not completed when the forward jog (BFM#26 b4), reverse jog
(BFM#26 b5) or other plural positioning operation commands are ON at the same time.

Small travel

1st-speed positioning operation
Trapezoidal control
(BFM36 b11 OFF)
Travel time < Acceleration time + Deceleration time
• If the time required for the travel (BFM#14, #13, #18, #17) is shorter than the acceleration/
deceleration time, the practical operation does not reach the set operation speed.
Interrupt 1st-speed positioning
Trapezoidal control
(BFM#36 b11 OFF)
• If the time required for the travel (BFM#14, #13) is shorter than the deceleration time, the
pulse output will be stopped when it reaches the target address Ι (BFM#14, #13) during
deceleration.
• If the travel is 0, it will immediately stop when the interrupt input X0 is turned on.

Time
Approx. S-shaped control
(BFM#36 b11 ON)
Since deceleration is slower on the
approx. S-shaped control than on the
trapezoidal control, the time to stop
becomes slightly shorter but the travel
stroke is equal to that of the trapezoidal
control.
