1.2.2 Differences between Q173HCPU/Q172HCPU and Q173CPU(N)/Q172CPU(N)

Item
Number of control axes
Operation cycle
(Default)
(It can be set up by parameters.)
Peripheral devices I/F
Servo amplifier I/F
Indirect setting of home position
return data
Expansion of speed setting range in
the unit [degree]
Fetch of external signal input
Optional data monitor function
Minor error [303], [304]
Processing with power supply OFF
of servo amplifier
Back-up battery for internal memory
(Note-1) : Use the dividing unit (Q173DV) or dividing cable (Q173J2B CBL M/Q173HB CBL M).
(Note-2) : When selecting the each servo amplifier general input, the home position return by the count type cannot be executed. And, the
external stop input cannot be used.
(Note-3) : When adding the external battery (Q6BAT), use the Q170HBATC.
(Note-4) : When adding the external battery (A6BAT/MR-BAT), use the Q173DV (Q173CPU(N) use) or Q170BAT (Q172CPU(N) use).

• When the speed control 10 multiplier setting
for degree axis is valid ;
0.01 to 21474836.47[degree/min]
• When the speed control 10 multiplier setting
for degree axis is invalid ;
0.001 to 2147483.647[degree/min]
Q172LX/General input of servo amplifier
3 points/axis (Specified device D, W, #)
When the speed change is executed after
positioning automatic decerelation start or during
decerelation by the JOG start command signal
(M3202+20n, M3203+20n) OFF, since the
speed change request is ignored, a minor error
[303], [304] will not occur.
Servo OFF is executed for all servo amplifier
connected behind servo amplifier with which the
control power supply was turned OFF.
Internal rechargeable battery
(Set the external battery (Q6BAT) if continuous
power off time is longer for 1 month or more.)
