Motor system and combined system:
Machine system:
This is the second operating speed in two-speed
positioning operation within the range between the bias
speed Vbia and the maximum speed Vmax.
[ BFMs #27 and #26 ] Current position CP
Motor system: -2,147,483,648 to +2,147,483,647 PPS
Machine system and combined system:
-2,147,483,648 to +2,147,483,647
The current position data is automatically written here.
When the value set here is read by the PC for
monitoring, make sure to read it in the unit of 32 bits.

When setting the speed data using the machine system
of units, make sure that the value converted into pulses
is within the range determined for the motor system and
the combined system (PPS).

The frequency f of the pulse generated in the PGU is
stepwise as follows.
f =
Where, n: Integer in range of 40 to 400,000
For example, in the case of n = 40, f = 100,000 PPS
Any pulse whose frequency is between the two
values above cannot be generated.
