Note.

For MITSUBISHI ELECTRIC SYSTEM & SERVICE CO., LTD MELSEC iQ-R series,

MELSEC-Q series and MELSEC-L series, the logic means N-side waveform. Therefore,

reverse the input pulse logic of the driver.

(1) Pulse train input

(a) Input pulse waveform selection

You can input command pulses in any of three different forms, and can choose positive or negative

logic. Set the command pulse train form in [Pr. PA13]. Refer to section 5.2.1 for details.

(b) Connection and waveform

1) Open-collector type

Connect as follows.

For source input interface

Note.

Pulse train input interface is comprised of a photocoupler.

If a resistor is connected to the pulse train signal line, it may malfunction due to reduction in current.
