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 manuals.

• 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 the
"Characteristics of electromagnetic brake" section in the chapter of the applicable rotary servo motor series.
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 parameters of the servo
amplifier. For details, refer to "Machine resonance suppression filter" in the following manual.

Selection of surge absorbers for electromagnetic brake circuit
The following shows an example of how to select a varistor as a surge absorber.
■Selection conditions
■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.

1.5 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, D-cut shaft, L-cut shaft, keyed shaft (with double
round-ended key), keyed shaft (without key), and keyed shaft (with single pointed key).
The keyed shaft (with single pointed key) supports only geared servo motors for high precision applications.

1.7 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 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.
