MR-J4-B-RJ020 Connections with Peripheral Equipment
(Note 1, 2)
Precautions
Installation
l
Mounting holes are not compatible with those of MR-J2S-_B_.
l
Dimensions of MR-J4-_B_ combined with MR-J4-T20 are different from
those of MR-J2S-_B_.
Wiring
l
The wire size is different from that of MR-J2S-_B_ depending on the capacity.
l
Options/peripheral equipment for MR-J2S series cannot be used except
the SSCNET cable and the terminal connector. Select options/ peripheral
equipment for MR-J4 series.
l
For RS-232C communication, use RS-232C cable (MR-CPCATCBL3M)
with junction cable (MR-J4T20CH00).
l
MR-J4-_B_-RJ020 servo is not equipped with 24 V power supply for
interface. When using digital I/O signal, 24 V (current capacity 0.1 A) power
supply is separately required as an interface power supply.
l
The signal wiring of connector for I/O signal (CN3) of MR-J4-_B_-RJ020 is
partially different from that of MR-J2S-_B_.
l
Use MR-BAT6V1SET when configuring absolute position detection system.
Function/performance
l
Adaptive vibration suppression control (parameter No. 25) is not available.
l
Alarms are displayed in two digits, which is the same as MR-J2S-_B_.
Some alarms are displayed in three digits.
l
Use MR Configurator (MRZJW3-SETUP161E). Note that the following
functions are not available.
- Gain search
- Machine simulation
- Motor-less operation (Motor-less operation by the parameter setting is available.)
l
Servo motors that are compatible with MR-J4 (HG series) may have
different coasting distance for dynamic brake from that of conventional
HC/HA series servo motors.
l
The encoder resolution of HG series servo motors will be 131072
pulses/rev (17 bit).
Refer to "MR-J4-_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual" for details.
RS-232C communication connector
(CN30)
Connect a personal computer and perform
parameter setting and monitoring with
MR Configurator. Use optional RS-232C cable
(MR-CPCATCBL3M) with junction cable
(MR-J4T20CH00).
Connector for SSCNET cable
connection (CN10B)
Connect the next servo amplifier axis or
MR-A-TM terminal connector.
Battery connector (CN4)
Connect MR-BAT6V1SET battery when
configuring absolute position detection
system.
Charge lamp
The lamp lights when the main circuit power
supply is charged.
Encoder connector (CN2)
Connect the servo motor encoder using an
optional cable or a connector set.
Magnetic contactor (MC)
This turns off the power to the servo
amplifier when an alarm is triggered.
Servo motor power cable (optional)
MR Configurator
(Setup software)
Servo motor
(The picture is as of HG-KR053.)
Battery
Encoder cable (optional)
Manufacturer setting connector (CN2L)
This connector is not for use.
Molded-case circuit breaker
(MCCB)
This protects the power supply line.
Power factor improving DC reactor (optional)
This boosts the power factor of servo
amplifier and reduces the power
supply capacity.
I/O signal connector (CN3)
This connector is used for forced stop input and electromagnetic brake
interlock signals. The signal wiring is partially different from that of MR-J2S-B.
Refer to "MR-J4-_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual."
When using digital I/O signal, 24 V power supply is separately required as an
interface power supply.
USB communication connector (CN5)
This connector is not for use in the J2S compatibility mode.
Axis setting part
(Note 3)
Select an axis with the axis selection rotary switch (SW1).
The control axis setting switches (SW2) are not for use in
the J2S compatibility mode. Set all to "off (bottom)."
Display
(Note 3)
Servo amplifier
status and alarm
number are
displayed.
(Note 4)
(Note 5)
Connector for SSCNET cable
connection (CN10A)
Connect the servo system controller
or the previous servo amplifier axis.
