[ BFMs#24 and #23 ] Operating speed (II) V(II)
Motor system and combined system:
10 to 100,000 Hz
Machinesystem:
1 to 153,000
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 Hz
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, makesureto read it in theunit of 32 bits.
< Conversion of system of units >
The following relationship is present
between the motor system of units and the machine
system of units. They are automatically converted each
other.
Speed command
A

cm/min, 10deg/min, inch/min
B1, B2 or B3
= Speed command (Hz) x 60
A indicates the pulse rate.
B1 to B3 indicate the
feedrate. PPS indicates the pulses per second.
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 (Hz).
< Stepwise speed command value >
The frequency f of the pulse generated in the PGU is
stepwise as follows.

= 10 to 100,000 Hz

Where, n: Integer in range of 40 to 400,000
For example, in the case of n = 40, f = 100,000 Hz
in thecaseof n = 41, f = 97,560 Hz
Any pulse whose frequency is between the two
values above cannot be generated.
