Sumitomo ASTERO BASA User manual

2.Brake pack characteristics
Sumitomo's brake packs are non contact types that can instantly stop induction motors or reversible motors by electronic braking. The
motor alone can be stopped in less than about 0.1 second. A braking current is applied to the motor for about 0.4 second, then the motor's
input power supply is automatically shut o. Unlike electromagnetic brakes, brake packs don't store torque. Since they have no parts
to generate mechanical friction, they have long lives. To control a motor using brake packs, a DC power supply for the signal is required
(12~24VDC, 0.1A or larger).

1. Safety and other precautions
DANGER
Wiring
• Connect a power cable to the motor according to the connection diagram or maintenance
manual; otherwise, electric shock or re may result.(Without terminal box, exercise insulation in
the connecting part.)
• Do not forcibly curve, pull or clamp the power cable and lead wires; otherwise, electric shock may
result.
• Correctly ground the grounding bolt; otherwise, electric shock may result.
• Use power source stated in the nameplate; otherwise, motor's burning or re may result.
Operation
• Never approach or touch any rotating parts (shaft, etc.) during operation; otherwise, loose
clothing caught in these rotation parts may result in severe injury.
• When the power supply is interrupted, be sure to turn off the power switch. Unexpected
resumption of power may cause injury or damage to the equipment.
Daily inspection and maintenance
• Never approach or touch any rotating parts (shaft, etc.) during maintenance ; otherwise, loose
clothing caught in these rotating parts may result in severe injury.
Inspection upon delivery
• Verify that the unit received is in fact the one ordered. When a dierent product is installed, injury
or damage to the system may result.
CAUTION
General
• The gear head and motor should be operated only within its name plate and catalogue ; otherwise, electric
shock, injury or damage to a system may occur.
• Keep hands and all foreign objects from the internal moving part of the gear unit and motor; otherwise,
electric shock, injury, re or damage to a system may occur.
• Damaged units should be taken o-line; otherwise, injury or re may occur.
• Do not remove the nameplate.
• Any modications or alterations of any kind, to the unit, will void the warranty and all subsequent claims.
Transport
• Exercise ample care not to drop the unit and fall during transport.
Installation
• Do not place any inammables around the gear head and motor; otherwise, re may result.
• Do not place any objects that will hinder ventilation around motor; otherwise, cooling eect is reduced, and
may lead to a possible re hazard and a burn due to excessive heat built-up.
• Do not touch the key way at the shaft end or on the inside of the dear unit and motor; otherwise, injury may
result.
• When the unit is used in food processing applications vulnerable to oil contamination, install an oil pan or
other such device to cope with rare oil leaking. Otherwise, oil leakage may damage products.
Coupling with other machines
• Install appropriate guard devices around rotation parts ; otherwise, injury may result.
• Conrm the direction of rotation before coupling the unit with its driven machine. Dierence in the direction
of rotation may cause injury or damage to the system.
Wiring
• Do not touch lead wire when measuring the insulation resistance. Electric shock may result.
Brake Pack Maintenance Manual
The gear head and motor should be handled, installed and maintained by trained technicians. Carefully read this manual and all
accompanying documents before use.
A copy of this manual should be sent to the actual user of the gear unit.
This manual should be maintained by the user.

* When making the brake a short cycle of 5 sec or less, use wiring for 60W or
90W. (Using external resister for brake)
* Use external resister for brake(30Ω 20W).

7.Input signal and motor operation (Fig.1)
• Clockwise (CW) operation input (induction motors)
When the CW operation input is turned ON, the motor shaft rotates clockwise. When turned OFF, the motor stops instantly. Induction
motors operate using the CW operation input. When connected as shown in the diagram, the motor operates in the clockwise direction.
To operate the motor counterclockwise, switch the gray and brown motor lead wires (the white and brown wires for a 220 to 240V/50Hz
motor).
• Counterclockwise (CCW) operation input (reversible motors)
When the CCW operation input is turned ON, the motor shaft rotates counterclockwise. When turned OFF, the motor stops instantly.
If the CW and CCW operation inputs are both turned ON at the same time, CW is given priority.
• Brake release input (induction motors, reversible motors)
When the brake release input is turned ON, the electronic brake won't operate. If the CW or CCW input is turned OFF in this condition, the
motor stops naturally after losing its inertia. If the brake release input is turned OFF, the electronic brake will operate. If the CW or CCW
input is turned OFF in this condition, the motor stops instantly.
8.Wiring connection cautions
• Don't try to switch the motor's operation direction in the 0.5-second interval after an instant motor stop.
• When using a short motor operation cycle, be sure the surface temperature of the motor case doesn't exceed 90°C.
• Don't start or stop the motor by turning the AC power supply ON/OFF, as surge voltage from the switch may cause product damage.
• Turn the power OFF when the motor is not in use for extended periods.
• Use the shortest possible distance when wiring the motor and brake pack, and brake pack and external controller.
• Use wires with a across-sectional area of at least 0.75mm for the motor wiring and AC power wiring.
• Don't bundle the motor wiring/AC power wiring (terminal Nos. 1, 2, 3, 9 and 10) with the signal wiring (terminal Nos. 4, 5, 6, 7 and 8). Install
the two sets of wiring at least 10cm apart.
• Don't solder anything to the brake pack's terminal pins directly.
• Turn the power OFF before inserting the brake pack into the socket, Insert the brake pack securely.
• Always ground the terminal of pin No.6, if motor operation will include instant stops.
