• When the power of the PGU is turned off,
the BFM data is cleared.
When the power of the PGU is turned on,
the initial values are entered to the BFMs.
• The BFMs #0, #1 and #2 are neglected
when the BFM #3 (b1, b0) is set to the
motor system.
• When each BFM is written or read, 16-bit
data shall be written/read in the unit of 16
bits and 32-bit data shall be written/read in
the unit of 32 bits.
< Reading of 32-bit data >
• At BFM #19 and #20, variable speed
operation and external command positioning
operation, can set a negative value. (-10 to
-100,000 Hz)

*3 Only one bit among the BFM #25 b6 to b4 and b12 to b8 can be turned on. If two or more bits among them
are turned on, no operation is performed.
*4 When data is written into the BFMs #0, #1, #2, #3, #4, #5, #6 and #15, data is calculated inside the PGU during
the first positioning operation. To save this processing time (500 ms maximum).
