Detailed Explanation Of Interfaces - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

*1 The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they can be
configured by one.
*2 The signal cannot be used in the velocity mode and torque mode.
*3 This diagram shows sink I/O interface. For source I/O interface, refer to the following.
Page 118 Source I/O interface
*4 Refer to the following for connections of external encoders.
Page 18 Summary
*5 The device is available only with MR-J4-_GF_-RJ.

Detailed explanation of interfaces

This section provides the details of the I/O signal interfaces (refer to the I/O division in the table) given in the following section.
Refer to this section and make connection with the external device.

Digital input interface DI-1
This is an input circuit whose photocoupler cathode side is input terminal. Transmit signals from sink (open-collector) type
transistor output, relay switch, etc. The following is a connection diagram for sink input. Refer to the following for source input.

*1 It will be approximately 4.3 k for interface of CN3-1 and CN3-10 pins.
Digital output interface DO-1
This is a circuit in which the collector of the output transistor is the output terminal. When the output transistor is turned on, the
current will flow to the collector terminal.
A lamp, relay or photocoupler can be driven. Install a diode (D) for an inductive load, or install an inrush current suppressing
resistor (R) for a lamp load.
(Rated current: 40 mA or less, maximum current: 50 mA or less, inrush current: 100 mA or less) A maximum of 2.6 V voltage
drop occurs in the servo amplifier. The following shows a connection diagram for sink output. Refer to the following for source
output.
