VBMS [20A]

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for the VBMS motor control and braking system, suitable for asynchronous motors. It highlights features, functions, technical data, and connection diagrams.

Specifications:

Motor control and DC-brake integrated into a single device.
Microcontroller-based control suitable for all asynchronous motors.
Easy mounting on a 35mm top-hat rail, suitable for retrofitting.
Motor contactor with a contact gap of ≥ 3mm, AC-3 utilization category.
Operator controls are physically separated from the load, using 24V extra-low voltage.
Multiple 'STOP' buttons can be connected.
Degree of protection: IP 20, compliant with trade association requirements for category 2 according to GS-HO-01.

Functions:

Direct online start via motor contactor.
DC braking with adjustable braking current and standstill threshold.
Braking current cutoff after motor standstill and monitoring of braking frequency.
Overload protection and start interlock in case of safety-relevant errors.

Technical Data:

Rated operational voltage: 50/60Hz, 3x 380/415V ± 10% or 3x 200/240V ± 10%.
AC-3 rated operational power: 2.2kW or 1.5kW.
Braking current range: 2 to 20A, with a maximum braking time of 10s.
Delay time during switch-off and braking: 500ms.
Braking voltage: 0 to 220V DC or 0 to 110V DC.
Ambient/storage temperature: 0°C to 45°C / -25°C to 75°C.
Weight: 0.6 kg.

Recommendations:

For IE3 motors, consider higher starting and braking currents when dimensioning soft starters and DC brakes. It is recommended to use devices one size larger.

Connection Diagrams:

Detailed diagrams for connecting start/stop buttons, single-phase motors, and motor protection relays are provided.

Applications:

Suitable for use in saws, milling machines, shakers, and other similar equipment.
