EIP: External Input Pin Status

The ON/OFF statuses of the input pins are sent back. Command of each bit is transmitted to the master station as hexadecimal data (1: ON, 0: OFF). Bits b31–b0 map to CN1 connector pins as follows:

EOP: External Output Pin Status

The slave station sends back the ON/OFF statuses of the output pins. Command of each bit is transmitted to the master station as hexadecimal data (1: ON, 0: OFF). Bits b31–b0 map to CN1 connector pins as follows:

The Status register provides amplifier status information. The address values correspond to the following items:

Jog Mode and Positioning Mode

The following instructions describe how to use EBPro (EasyBuilder8000 / EasyBuilderPro) to run Jog Mode and Positioning Mode with the Mitsubishi MR-J3/J4-A servo amplifier.

Jog Mode

To run Jog Mode, follow the steps listed sequentially:

1. Set Jog Mode
2. Set rotation speed
3. Set acceleration
4. Set forward / reverse rotation direction
5. End

In the EBPro (EasyBuilder8000 / EasyBuilderPro) editing window, set the write address of Speed to Local HMI LW0 (the address can be user-defined) and set Acc (Acceleration) to LW1.

Start Macro

macro_command main()
short speed
short acc
short mode
mode = 1  // This represents Jog Mode.
SetData(mode, "MITSUBISHI MR J3 A", Mode, 1, 1)  // Set driver mode to Jog.
GetData(speed, "Local HMI", LW, 0, 1)  // Save LW0 value to speed.
SetData(speed, "MITSUBISHI MR J3 A", Speed, 0, 1) // Set motor operating speed.
GetData(acc, "Local HMI", LW, 1, 1)
SetData(acc, "MITSUBISHI MR J3 A", Acc, 0, 1) // Set motor acceleration.
short motion
motion = 0x0801  // Special code, see Note 1.
SetData(motion, "MITSUBISHI MR J3 A", Rotation, 0, 1) // Rotate.
end macro_commandCode language: JavaScript (javascript)

End Macro

macro_command main()
short stop
stop = 1  // See Note 2.
SetData(stop, "MITSUBISHI MR J3 A", End, 1, 1)
end macro_commandCode language: JavaScript (javascript)

Positioning Mode

In the EBPro (EasyBuilder8000 / EasyBuilderPro) editing window, set the write address of Speed to Local HMI LW2 (the address can be user-defined), set Acc (Acceleration) to LW3, and set Move distance to LW4 (DW format).

Positioning Macro

macro_command main()
short mode
mode = 0x2  // Positioning Mode
SetData(mode, "MITSUBISHI MR J3 A", Mode, 1, 1)
short speed
GetData(speed, "Local HMI", LW, 2, 1)
SetData(speed, "MITSUBISHI MR J3 A", Speed, 0, 1)
short acc
GetData(acc, "Local HMI", LW, 3, 1)
SetData(acc, "MITSUBISHI MR J3 A", Acc, 0, 1)
short dist
GetData(dist, "Local HMI", LW, 4, 1)
SetData(dist, "MITSUBISHI MR J3 A", M_dist, 0, 1)
short rot_P
rot_P = 1        // Set to 0: Forward Rotation  1: Reverse Rotation
SetData(rot_P, "MITSUBISHI MR J3 A", Rot_P, 0, 1)
short rotat
rotat = 1   // See Note 3.
SetData(rotat, "MITSUBISHI MR J3 A", Rotation, 0, 1)
SetData(rot_P, "MITSUBISHI MR J3 A", P_start, 0, 1) // Start Positioning.
