Items To Be Observed When Using the Main Unit (Transistor Output)

1. Pulse output destination devices
Use Y000, Y001, and Y002
Do not use the transistor output Y003 of the main unit for positioning instructions. If Y003 is used for a positioning
instruction, PLC failure may occur.
2. Pulse output method
Adjust the pulse output method of the transistor output of the main unit to conform with 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 a pulse frequency of more than 100,000 Hz is output from the transistor output terminal of the main unit to
perform the operation, it may cause PLC failure.
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 the transistor output Y000, Y001, or Y002
load current of the open collector transistor output to 10 to 100 mA (5 to 24V DC).
