Speed Data and Position Data
[ BFMs#5 and #4 ] Maximum speed V
max
Motor system and combined system:
10 to 100,000 Hz
Machinesystem: 1 to 153,000
This is themaximum speed. Makesurethat thebias
speed (BFM #6), the JOG speed (BFMs #7 and #8), the
home position return speed (BFMs #9 and #10), the
creep speed (BFM #11), the operating speed (I) (BFMs
#19 and #20) and the operating speed (II) (BFMs #23
and #24) are set respectively to a value equivalent to or
less than the maximum speed.
The degree of acceleration/deceleration is determined
by this maximum speed, the bias speed (BFM #6) and
the acceleration/deceleration time (BFM #15).
[ BFM #6 ] Biasspeed V
bia
Motor system and combined system:
0 to 10,000 Hz
Machinesystem: 0 to 15,300
This is the bias speed at time of start.
When the FX(2N)-1PG and the stepper motor are used
together, set a value while taking the resonance area
and the self-start frequency of the stepper motor into
account.
[ BFMs#8 and #7 ] JOG speed V
JOG
Motor system and combined system:
10 to 100,000 Hz
Machinesystem: 1 to 153,000
This is the speed for manual forward/reverse
(JOG+/JOG-).
Set a value between the bias speed
V
bia
and themaximum speed V
max
.
[ BFMs #10 and #9 ] Home position return speed
(high speed) V
RT
Motor system and combined system:
10 to 100,000 Hz
Machinesystem: 1 to 153,000
This is the speed (high speed) for returning to the
machinehome position.
Set a value between the bias speed Vbia and the
maximum speed V
max
.
[ BFM #11 ]
Home position return speed (creep)
V
CR
Motor system and combined system:
10 to 10,000 Hz
Machinesystem: 1 to 15,300
This is the speed (extremely slow speed) after the near
point signal (DOG) for returning to the machine home
position.
It is the speed immediately before stopping in the
machine home position. It is recommended to set it as
slow as possibleso that thepre
cision of thehome
position becomes better.
[ BFM #12 ]
Number of zero point signals for
home position return N
0 to 32,767 PLS
This is the number of zero point signals counted for
returning to the machine home position.
When the zero point signal is not used and the machine
should be stopped immediately by only the DOG input,
set the BFM #12 to 0. However, pay rigid attention so
