SAFETY, INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR BRAKE MOTORS - AMBY SERIES
HIGH-TORQUE D.C. BRAKE
GENERAL SAFETY INSTRUCTIONS
Danger: electric rotating machine have dangerous rotating and conductive parts, as well as possibly hot surfaces.
The commissioning of electric motor is forbidden until the machine on which it has been incorporated has been declared conform to
2006/42/EC directive (Machine Directive).
All transportation, storage, installation, commissioning, inspection, maintenance and repair works have to be carried out exclusively
by qualified personnel (definition according to IEC 364) according to EN 60204-1.
Improper use may cause major damage to persons and objects.
Motors meet the requirements of Low Voltage Directive 2006/95/EC and are therefore CE marked on name plate.
Operating conditions have to be according to EN 60034-1.
BRAKE MOTORS INSTALLATION
The responsibility of the correct brake functionality is completely of the installer, who has to:
comply with the connection scheme placed inside the terminal box
supply the rectifier / brake according to the data on the nameplate / connection scheme
check the correct brake functionality
check that the brake torque satisfies the application needs
supply in a correct way auxiliary equipments, if any (see specific documentation)
Earthing has always to be carried out (according to local regulations) before the connection to the mains.
The supply of motor, rectifier/brake, auxiliary equipments (if any) has to be made using cables of suitable section in order to avoid
overheating and/or too high voltage drop.
Pay attention not to alter the protection degree (use only original gaskets).
In case of brake motor inverter supply follow correctly the wiring instructions of the inverter manufacturer and separately supply
(directly from the main) the rectifier/brake.
For any special design see specific documentation.
The good brake running in time depends on a correct periodical maintenance.

  • Page 2 PERIODICAL MAINTENANCE OF BRAKE MOTORS Every maintenance work on brake motors should only be carried out by qualified personnel, always with the machine out of operation, disconnected and previously secured against starting. Brake motors with high-torque D.C. brake (with electromagnetic brake braking in case of failure supply) have got braking torque already preset at rated plate value, according to catalogue (braking torque adjustment upon braking springs number up to 250Nm ) that means that the periodical maintenance consists on checking that the air-gap “t”, the minimum friction surface thickness “S...
