6.2.2 Setting of servo amplifier series

Symbol Item
Servo amplifier
Pr.300
series
Up to 8 axes servo amplifies in QD74MH8 and up to 16 axes servo amplifies in
QD74MH16 can be connected. Set the servo amplifier series in the servo parameter
for each axis.

3: MR-J3-B (Fully closed loop control)
4: MR-J3-B (Linear)
Communication with servo amplifiers is possible setting by the servo amplifier series.
The procedure to communicate with servo amplifiers is shown below.
Turn ON the system power supply.
Set the servo amplifier series.
Turn ON the control power supply
of servo amplifier.
Turn ON the PLC REDEY.
Communiction start with servo
amplifier.
POINT
(1) The communicate with servo amplifiers can be executed at the first PLC
READY ON after the system power supply ON.
An error code 400 will occur and the unit READY does not turn ON in the
following cases.
• The servo amplifiers corresponding to servo amplifier series cannot be
connected.
• The power supply of servo amplifiers are OFF.
The communication does not start and the error reset cannot be executed,
even if the power supply of servo amplifier is turned ON. Turn the PLC READY
ON after the power supply ON for all axes.
(2) The communication continues even if the PLC READY is turned OFF after
communication start with the servo amplifiers.
(3) The servo amplifier series cannot be changed after the PLC READY ON.
Set it before PLC READY ON in the following procedure.
• Write the data to the flash ROM beforehand.
• Set the servo amplifier series before the PLC READY ON, after turning
ON/OFF of the system power supply or reset of the PLC CPU.
(4) If the power supply of the servo amplifier is turned OFF after communication
start with the servo amplifiers, an error code 400 will occur, and the unit
READY turns OFF. The communication does not start and the error reset
cannot be executed, even if the power supply of servo amplifier is turned ON.
Set the servo amplifiers connected to QD74MH.
It is not necessary to set every time, if the flash ROM write
is executed once after setting of the servo amplifier series.
