Rotation Direction; Positioning Complete Flag (Bfm#28 B6); Stop Command - Mitsubishi Electric FX2N-10PG User Manual

Model FX2N-10PG Pulse Output Block
8.6.4

Rotation direction

Absolute address mode : The rotation direction is determined depending on the large/small
Relative address mode : The rotation direction is determined depending on the symbol
When absolute address is used, the reverse rotation sometimes occurs depending on the
small/large relationship of the current address, target address Ι (BFM#14, #13) of 1st speed,
and target address ΙΙ (BFM#18, #17) of 2nd speed.
Moreover, when the relative address is instructed, the reverse rotation occurs if the symbols
(positive/negative) of target address Ι and target address ΙΙ are different.
Caution
The rapid change of rotation direction may break the machine.
Also, it will cause an error to occur if the motor is overloaded.
If any stop time is required when the rotation direction is changed during operation, the
operation is applied according to the 1st-speed positioning operation.

Positioning complete flag (BFM#28 b6)

The positioning complete flag (BFM#28 b6) is reset with START input, START command
(BFM#26 b9), forward jog (BFM#26 b4), reverse jog (BFM#26 b5), zero return (BFM#26 b6),
data set type zero return (BFM#26 b7), variable-speed operation, manual pulse generator
input operation or power shutdown, and is turned ON when the target address is reached.
However, it is not reset with START input or START command when the travel is 0.
(When OFF before start of positioning, the flag is turned ON.)
• When positioning operation is stopped with STOP command, the positioning completed flag
(BFM#28 b6) is not turned ON.
If the STOP command is received in the deceleration process to the target address, the
work is stopped when it arrives at the target address as the gradient of the deceleration is
the same.
At this time, the positioning complete flag (BFM#28 b6) is not turned ON.

STOP command

When STOP command (BFM#26 b1) is turned ON, the work is decelerated and stopped.
When restarted, the operation is different depending on the setting of parameter (BFM#36
b15).
BFM#36 b15=0 : The remaining-distance operation is executed with restart.
BFM#36 b15=1 : The 2nd-speed positioning operation is ended, and the next new
relationship between the current address (BFM#25, #24) and target
address Ι (BFM#14, #13).
(positive/negative) of target address Ι
positioning operation is started.
