Power supply explanations
■
DICOM (Digital I/F power supply input)
Input 24 V DC (24 V DC ± 10 %) for I/O interface. The power supply capacity varies depending on the number of I/O interface
points to be used. It is 300 mA for the MR-J5-_G_, and it is 500 mA for the MR-J5-_A_.
For sink interfaces, connect the positive terminal of the 24 V DC external power supply.
For source interfaces, connect the negative terminal of the 24 V DC external power supply.
■
DOCOM (Digital I/F common)
DOCOM is a common terminal of input signals such as EM2 of the servo amplifier. This is separated from LG.
For sink interfaces, connect the negative terminal of the 24 V DC external power supply.
For source interfaces, connect the positive terminal of the 24 V DC external power supply.
■
LG (Monitor common)
LG is a common terminal of MO1 and MO2.
■
SD (Shield)
Connect the external conductor of a shielded wire to SD.
Power supply explanation [A]
■
OPC (Open-collector - Sink interface power supply input)
• Position control mode
When inputting a pulse train in the open-collector type with sink interface, supply the positive power of 24 V DC to this
terminal.
• Speed control mode/torque control mode
Supply the positive (+) power of 24 V DC to this terminal if using the CN3-10 pin and CN3-35 pin for DI. The CN3-10 pin and
CN3-35 pin can be used on the MR-J5-_A_-RJ_ servo amplifiers.
■
P15R (15 V DC Power supply output)
This outputs 15 V DC to between P15R and LG. This is available as a power supply for TC/TLA/VC/VLA.
Permissible current: 30 mA
■
LG (Control common)
This is a common terminal of TLA/TC/VC/VLA/OP/MO1/MO2/P15R. Each pin is connected internally.
