Items To Be Observed in Use of Main Unit (Transistor Output)

1. Pulse output destination devices
Use Y000, Y001, and Y002 transistor outputs of the main unit as the pulse output destination devices.
Do not use Y003 transistor output of the main unit for the positioning instructions. If Y003 is used for a positioning
instruction, the PLC may be damaged.
2. Pulse output method
Adjust the pulse output method of the transistor output of the main unit so that the pulse output method can
conform to the command pulse input method of the servo amplifier (drive unit).
If the pulse output method is not properly adjusted, the servo amplifier (drive unit) may not perform the
intended operation.
→ For details on the servo amplifier (drive unit), refer to the manual of the product used in your
3. Output pulse frequency (including zero return speed)
If the transistor output Y000, Y001, Y002 of main unit uses the pulse frequency of more than 100,000 Hz to
perform operation, the PLC may be damaged.
The output pulse frequency and the zero return speed should be equal to or less than the maximum
frequency of the servo amplifier (drive unit).
4. Load current
To use a positioning instruction for Y000, Y001, or Y002 transistor output of the main unit, adjust the load
current of the open collector transistor output to 10 to 100 mA (5 to 24V DC).

1. Output terminals to be used
If the high-speed output special adapter is connected, output numbers will be assigned in the same way as
the main unit as shown in the following table. Use the output terminals of one side (main unit side or high-
speed output special adapter side), and do not connect lines to the output terminals of unused side.
The outputs of high-speed output special adapter and the main unit will operate as follows.
