1.5 Electromagnetic brake
The rotary servo motor with an electromagnetic brake can be used to prevent a drop in vertical lift applications or to ensure
double safety at an emergency stop, for example. When operating the rotary servo motor, supply power to the
electromagnetic brake to release the brake. Switching power off enables the electromagnetic brake.
Precautions
• The electromagnetic brake on the rotary servo motor is designed to hold the motor shaft and should not be used for
ordinary braking.
• Incorrect wiring, service life, or the mechanical structure (e.g. where a ball screw and the rotary servo motor are coupled via
a timing belt) may cause the electromagnetic brake to be unable to hold the motor shaft. To ensure safety, install a stopper
on the machine side.
• If it is assumed that a power failure or product malfunction may result in a hazardous situation, use a rotary servo motor
with an electromagnetic brake or provide an external brake system for holding purpose to prevent such hazard.
• Configure an electromagnetic brake circuit that interlocks with the external emergency stop switch.
• The electromagnetic brake is provided to prevent a drop at a power failure or servo alarm occurrence during vertical drive
or to hold a shaft at a stop. Do not use it for normal braking (including braking at servo-lock).
• The electromagnetic brake has a release delay time. Ensure enough time between releasing the electromagnetic brake
and starting the rotary servo motor. Check the release delay time with an actual machine.
• For details of the circuit configuration, refer to "Servo motor with an electromagnetic brake" in the following manual.
MR-J5 User's Manual (Hardware)
• For details of the timing chart, refer to "Electromagnetic brake interlock function" in the following manual.
MR-J5 User's Manual (Function)
• When the electromagnetic brake is released, the temperature of the rotary servo motor may increase regardless of driving.
• The service life of the brake may be shortened under sudden acceleration/deceleration conditions.
Electromagnetic brake power supply
Prepare the following power supply for use with the electromagnetic brake only. The electromagnetic brake terminals (B1 and
B2) have no polarity.
A surge absorber (VAR) must be installed between B1 and B2. For a selection example of surge absorbers, refer to
"Characteristics of electromagnetic brake" in chapters 6 and 7.
When a diode is used as a surge absorber, the electromagnetic braking time becomes longer.

Sound generation
The brake lining may rattle during a low-speed operation; however, it poses no functional problem.
The noise may be reduced or eliminated by the machine resonance suppression filter set with the servo parameters. For
details, refer to "Machine resonance suppression filter" in the following manual.
MR-J5 User's Manual (Adjustment)
Selection of surge absorbers for electromagnetic brake circuit
The following shows an example of how to select a varistor as a surge absorber.
■Selection condition
■Tentative selection and verification of surge absorber
• Maximum permissible circuit voltage of varistor
Tentatively select a varistor whose maximum permissible voltage is larger than Vb [V].
• Brake current (Ib)
• Energy (E) generated by brake coil
• Varistor limit voltage (Vi)
From the energy (E) generated in the brake coil and the varistor characteristic diagram, calculate the varistor limit voltage (Vi)
when the brake current (Ib) flows into the tentatively selected varistor during opening of the circuit.
Vi is favorable when the varistor limit voltage (Vi) [V] is smaller than the desired suppressed voltage (Vs) [V].
If Vi is not smaller than Vs, reselect a varistor or improve the withstand voltage of devices.
• Surge current width ()
Given that the varistor absorbs all energies, the surge current width () is as follows.
• Examining surge life of varistor
From the varistor characteristic diagram, find the guaranteed current value (Ip) in which the number of the surge application
life is N at the surge current width (). Calculate the guaranteed current value (Ip) ratio (Ip/Ib) to brake current (Ib).
If a sufficient margin is ensured for Ip/Ib, the number of the surge application life N [time] can be considered as favorable.
Other precautions
A leakage magnetic flux occurs at the shaft end of the servo motor with an electromagnetic brake. Note that chips, screws,
and other debris are attracted.

1.6 Rotary servo motor shaft shapes
Do not use shafts other than the straight shaft for frequent start/stop applications. Use a friction coupling or the like when
coupling the shaft with a machine.
There are six shaft shape types for the rotary servo motor: straight shaft, keyed shaft (with double round-ended key), keyed
shaft (without key), D-cut shaft, keyed shaft (with single pointed key), and L-cut shaft.
The keyed shaft (with single pointed key) supports only geared servo motors for high precision applications.

1.7 Servo motors with functional safety
The HK-KT series, HK-ST series, and HK-RT series support servo motors with functional safety. The specifications and
dimensions of servo motors with functional safety are not changed.
For the available safety-sub functions and the achievable safety levels, refer to "Functional safety" in the User's Manual
(Introduction).
1.8 Instructions on storage
Precautions
Note the following when storing the rotary servo motor for an extended period of time (guideline: three or more months).
• Always store the linear servo motor indoors in a clean and dry place.
• When storing in a dusty and humid area, take measures such as covering the whole product.
• If the insulation resistance of the magnet wire decreases, reconsider how the equipment is being stored.
• Although the servo motor has been given rust prevention treatment with paint and preventive oil before shipment, rust may
still appear depending on the storage period and conditions. If the servo motor is to be stored for longer than six months,
apply rust prevention oil again, especially to the machined surfaces of the shaft and other parts.
• Before using the product after an extended storage, hand-turn the rotary servo motor output shaft and check to ensure that
there is no abnormality. For the rotary servo motor with an electromagnetic brake, check it after releasing the
electromagnetic brake with the brake power supply.
• When the product has been stored for an extended period of time, contact your local sales office.
1.9 Instructions on maintenance
Precautions
• To prevent the scuffed surface, do not scratch the coated surface with hard objects nor clean the coated surface with an
organic solvent.
• For repair and parts replacement, contact your local sales office.
1.10 Instructions on protection
Precautions
• Provide adequate protection to prevent an unexpected restart after an instantaneous power failure.

18 2 INSTALLATION
2INSTALLATION
Precautions
• Install the rotary servo motor on incombustible material. Installing them either directly on or near combustibles may lead to
smoke or a fire.
• Provide adequate protection so as to prevent conductive matter (such as screws and metal fragments) and combustible
matter (such as oil) from entering the rotary servo motor.
• The temperature of the rotary servo motor may exceed 100 °C depending on the operating method. Take safety measures
such as providing covers.
• The eyebolts of the rotary servo motor are only for transportation of the rotary servo motor.
• Do not use them to transport the rotary servo motor when it is mounted on a machine.
• Be sure to install the geared servo motor in the specified direction. Not doing so will cause oil leakage, which may lead to a
fire and malfunction.
• Do not overtighten the eyebolts of the rotary servo motor. To prevent damage to the tap, avoid tightening too hard.
• Do not stack in excess of the specified number of product packages.
• Do not carry the rotary servo motor by the cables, connectors, or encoder. Doing so may cause the rotary servo motor to
drop.
• When installing the rotary servo motor, follow the user's manual and install the motor in a place that can support its weight.
• Do not install or operate any rotary servo motor that is missing parts or is damaged.
• Securely fix the rotary servo motor to a machine. If attached insecurely, the motor may come off during operation.
• To prevent a connection failure, malfunction, or similar problem, do not strike the connector.
• Be sure to measure the vibration level with the rotary servo motor mounted on the machine. A great vibration may cause
early damage to a bearing, encoder, brake, and gear reducer, and poor connector connection or bolt looseness.
• For the gain adjustment at the equipment startup, check the torque waveform and the speed waveform with a
measurement device to check that no vibration occurs. If the vibration occurs due to high gain, the vibration may cause
early damage to the rotary servo motor.
• Use the product within the specified environment. For the environment, refer to the specifications of the rotary servo motor
series.
• To prevent an encoder malfunction from occurring, do not apply shocks, e.g. hit with a hammer, when coupling the shaft
end of the rotary servo motor.
• To prevent the shaft from being broken, do not subject the shaft of the rotary servo motor to more than the permissible load.
• To prevent the shaft from being broken and bearing from being worn out, do not use a rigid coupling when coupling a load
to the rotary servo motor.
• To prevent vibration during rotary servo motor operation and to prevent damage to the bearings and encoder, the balance
level of the load needs to be as even as possible.
• To prevent a malfunction, do not use the rotary servo motor where the shaft-through portion may be subject to pressure
(e.g. compressed air).
• Take safety measures such as providing covers to avoid accidentally touching the rotor of rotary servo motor during
operation.
• Do not get on the equipment or put a heavy load on it.
• Do not drop or strike the rotary servo motor.
• To prevent a fire or injury from occurring in case of an earthquake or other natural disasters, securely install, mount, and
wire the rotary servo motor in accordance with the user's manual.
• To prevent an electric shock or a fire, do not disassemble, repair, or modify the product. Disassembled, repaired, and/or
modified products are not covered under warranty.
• The equipment must be installed in the specified direction.
• Do not use the product in environments where it is exposed to strong magnetic fields, electric fields, or radiation. Doing so
may cause operation failure or malfunction.
