Operation Command

[ BFM #25 ] Operation command (b0 to b11, b12)
After data is written to the BFMs #0 to #24, write the
BFM #25 (b0 to b12) as follows.
[b0] When b0 = 1: Error reset
The error flag (BFM #28 b7) described later is
reset.
[b1] When b1 = 0 → 1: Stop
This bit functions in the same way with the
STOP input in the PGU, but the stop operation
can be performed from the sequence program
in the PC.
However, if this bit is changed from 0 to 1
before the STOP input is given in the PGU in
the external command positioning mode, the
machine is decelerated and stopped.
[b2] When b2 = 1: Forward pulse stop
The forward pulse is stopped in the forward
limit position.
[b3] When b3 = 1: Reverse pulse stop
The reverse pulse is stopped in the reverse
limit position.
[b4] When b4 = 1: JOG+ operation
When b4 continues to be 1 for less than 300
ms, one forward pulse is generated.
When b4 continues to be 1 for 300 ms or more,
continuous forward pulses are generated.
[b5] When b5 = 1: JOG- operation
When b5 continues to be 1 for less than 300
ms, one reverse pulse is generated.
When b5 continues to be 1 for 300 ms or more,
continuous reverse pulses are generated.
BFM LIST
[b6] When b6 = 0 → 1: Home position return start
The machine starts to return to the home
position, and is stopped at the machine home
position when the DOG input (near point signal)
or the PG0 (zero point signal) is given.
[b7] When b7 = 0: Absolute position
When b7 = 1: Relative position
The relative or absolute position is specified in
accordance with the b7 status (1 or 0).
(This bit is valid while operation is performed
using b8, b9 or b10.)
[b8] When b8 = 0 → 1: Single-speed positioning
operation start
Single-speed positioning operation is
performed.
For the details, see Section 6.2.
[b9] When b9 = 0 → 1: Interrupt single-speed
positioning operation start
Interrupt single-speed positioning operation is
performed.
For the details, see Section 6.2.
[b10] When b10 = 0 → 1: Two-speed positioning
operation start
Two-speed positioning operation is performed.
For the details, see Section 6.3.
[b11] When b11 = 0 → 1: External command
positioning operation start
External command positioning operation is
performed. The rotation direction is
determined by the sign of the speed command.
For the details, see Section 6.3.
