bit5. Digital speed command input valid (deg)
This signal turns ON when the digital speed command input is closed (ON). When this signal is
turned ON, the speed command is determined by the external input R01(CN12-1 pin) to
R12(CN12-16 pin) 12bit. The com mon is CES2(CN12-19 pin).
The types of digital speed command include the followings, and one of them can be selected (by
the parameter).
1) BCD code 2 digits: 8bit
2) BCD code 3 digits: 12bit
3) Binary (12-bit binary): 12bit
4) Signed binary: 12bit

(Note) The table below indicates the state where the motor is run by the forward run start signal input.When the motor is run
by the reverse run start signal input, the rotation direction is revered.

bit6．Override analog input (OR1, OR2)
This signal turns ON when the override input is closed (ON: valid).
This is used apart from the speed command to change the motor rotation speed.
Note that, however, this input can be used only when the S analog speed command or digital
speed command is used, and the commanded voltage is input in the CN8A-7 pin in the case with
the S analog speed command input. This cannot be used when using the sp eed setting function.
The motor speed in respect to the CN8A-17 pin (OR2) input voltage is as shown below.
Motor speed
CN8A-17 pin
Input voltage
+10V 0
(120%)
(50%)
Motor regular speed (100%)
If the speed command is Nr/min now, the speed can be changed to 0.5-1.2Nr/min with this input.
With the input of 0V, 0.5Nr/min, with +10V, 1.2Nr/min can be achiev ed.
Note that, however, the speed is clamped at the motor maximum speed setting value (parameter:
SP017(TSP)).

bit7．S analog high-speed synchronous tapping
This signal turns ON when the S analog high-speed synchronous tapping input is closed (ON).

control "adjusting S analog high-speed synchronous tapping"
