Description
UNITROL 5000 ABB IN STOCK AND NEW
Where UNITROL 5000 operated under technically correct conditions, the service life is largely depend on the service life
of the bearing.
The following operating conditions may significantly reduce the service life of the motor:
• Installation at altitudes over 1000 m above mean sea level
• Continuous operating temperatures greater than 80°C
• Angular travel less than 100°
• Operation with very high rotation accelerations
• Operation und vibration loads greater than 20 m/s²
• High cyclic frequencies
• Running with dry sealing rings
• Wetting seals with aggressive media

3-phase stepping UNITROL 5000 can optionally be fitted with an encoder. This system of measurement returns the actual position if the power drive is equipped with a rotation monitoring circuit. The rotation monitoring circuit compares the setpoint and actual positions of the motor and signals an error if the difference between the two exceeds a certain limit (contouring error limit). This will detect overloading of the motor, for example.An Encoder can only be fitted on motors equipped with a receptacle. A second shaft end or a holding brake can also be used.

The holding brake is an electromagnetic spring-pressure brake which holds the motor shaft in position when there is no current to the motor (e.g. in the event of a power failure or emergency stop). UNITROL 5000 function is needed for applications in which weight on the shaft can cause excessive torque, e.g. the Z axes of handling equipment.The drive circuit must be electrically excited in order to disengage the brake. To prevent overheating, the excitation current should be reduced as soon as the brake is disengaged. The recommended circuit arrangement is shown in the following diagram.
