1. Use the following formula to calculate the running power and regenerative power of each servo motor from the servo
motor speed and torque.
Running power and regenerative power [W] = Servo motor speed [r/min] × Torque [N•m]/9.55
2. Calculate the total output power of the servo motors from the running power and regenerative power of each servo
motor.
• The effective value of the total servo motor output power [kW]
MR-CV18K4 or more
• Maximum value of the total servo motor output power [kW] × 1.2 = 21 kW × 1.2 = 25.2 kW
MR-CV11K4 or more
• Total drive unit width = 75 mm (MR-J5D2-700G4) + 60 mm (MR-J5D3-200G4) = 135 mm 1500 mm
Therefore, the power regeneration converter unit selected should be the "MR-CV18K4".

1.3 Combination with drive units and servo motors
By combining a servo motor with a larger capacity drive unit, the maximum torque can be increased to 400 % or 450 %.
Rotary servo motor
As long as the servo motor is compatible with the drive unit, any combination of the servo motor series and
capacity is possible.
HK-KT series
The combinations of geared servo motors and drive units are the same as those listed in the following table. However, for
geared servo motors, the maximum torque does not increase even when they are combined with a drive unit whose
combination allows for increased torque as specified in the following table.

• Check that the power to be supplied to the converter unit is not connected to the power outputs (U/V/W) of the drive unit.
Otherwise, the drive unit and the servo motor will malfunction.
• Check that the grounding terminal of the servo motor is connected to the grounding terminal of the CNP3_ connector of the
drive unit.
• Check that the CN2A connector and the encoder of the A-axis servo motor, the CN2B connector and the encoder of the B-
axis servo motor, and the CN2C connector and the encoder of the C-axis servo motor are securely connected in the drive
unit using a motor cable or encoder cable.
I/O signal wiring
• Check that I/O signals are connected correctly.
If the DO forced output mode is used, the pins of the CN3 connector can be forcibly switched on/off. This mode is used to
check the wiring. In this case, switch on the control circuit power supply only. Refer to the following page for information on
connecting I/O signals.
Page 48 Example I/O signal connections
• Check that a voltage exceeding 24 V DC has not been applied to the pins of the CN3 connector.

1.5 Surrounding environment
1.5 Surrounding environment
Check the following items about the environment surrounding the converter unit, drive unit, and servo motor.
Handling cables
• Check that the wiring cables have not been stressed.
• Check that the encoder cable has been used within its flex life.
Page 112 Cable flex life
• Check that the connector of the servo motor has not been stressed.
Environment
Check that signal cables and power cables have not been shorted primarily by wire offcuts and metallic dust.

2INSTALLATION
Precautions
• Mount the converter unit and drive unit on incombustible material. Installing them either directly on or near combustibles
may lead to smoke or a fire. In addition, the converter unit and drive unit must be installed in a metal cabinet.
• Provide adequate protection so as to prevent conductive matter (such as screws and metal fragments) and combustible
matter (such as oil) from entering the converter unit and drive unit.
• Devices such as the converter unit, drive unit, and servo motor may become hot. Take safety measures such as providing
covers.
• Do not stack in excess of the specified number of product packages.
• Do not hold the front cover, cables, or connectors when carrying the converter unit and drive unit. Doing so may cause the
drive unit to drop.
• To prevent a malfunction, do not drop the converter unit, drive unit, or servo motor or subject them to impacts.
• Install the converter unit, drive unit, and servo motor in a place that can support their weight as stated in the user's manual.
• Do not get on the equipment or put a heavy load on it.
• Do not install and operate a converter unit or drive unit that is missing parts or is damaged.
• To prevent a malfunction, do not block the intake and exhaust areas of the converter unit and drive unit.
• Do not subject connectors to impacts. Doing so may cause a connection failure, malfunction, or other failures.
• Use the product within the specified environment. For the environment, refer to "Drive unit standard specifications" in the
User's Manual (Introduction).
• To prevent a fire or injury from occurring in the event of an earthquake or other natural disaster, securely install, mount, and
wire the drive unit as stated in the user's manual.
• When the product has been stored for an extended period of time, contact your local sales office.
• When handling the converter unit and drive unit, pay attention to their corners.
• Fumigants that are used to disinfect and protect wooden packaging from insects contain halogens (such as fluorine,
chlorine, bromine, and iodine) cause damage if they enter our products. Please take necessary precautions to ensure that
any residual materials from fumigants do not enter our products, or perform disinfection and pest control using a method
other than fumigation, such as heat treatment. Perform disinfection and pest control on the wooden packaging materials
before packing the products.
• Provide an external emergency stop circuit to stop the operation and shut-off the power immediately.
• For equipment in which the moving part of the machine may collide against the load side, install a limit switch or stopper to
the end of the moving part.
• Do not use the drive unit in environments where it is exposed to strong magnetic fields, electric fields, or radiation. Doing so
may cause operation failure or malfunction.

2.1 Mounting direction and clearances
Precautions
• The converter unit and drive unit must be installed in the specified direction.
• To prevent a malfunction, maintain the specified clearances between the converter unit/drive unit and cabinet walls or other
equipment.
• Circulate air so that the air at the top and bottom of the converter unit and drive unit does not stagnate.
• When using heat-generating equipment, install it with full consideration of heat generation so that the converter unit and
drive unit are not affected.
• Mount the converter unit and drive unit on a perpendicular wall in the correct vertical direction.
