Electronic DC braking, suitable for all asynchronous motors, especially suitable for retrofitting into existing plants, extending the life of drive units by infinitely variable braking torque, wear-resistant and maintenance-free
PETER electronic has added the compact type series VersiBrake 230/400-25 L (LP) to its tried and tested product line of electronic DC brakes. The device, which features an upgraded power section designed for a rated device current of 25 A, is available either as a housing version or as a circuit-board version for rated motor currents up to 12.5 A. In preparation for the certification by the German Trade Association (Technical Committee for Wood), VersiBrake 230/400-25L (LP) already now meets the association's requirements for category 2 acc. to EN 954-1. VersiBrake 230/400-25 L (LP) features double safety protection: i.e., control via motor contactor and motor voltage detection. In addition, a surge suppressor circuit and a braking current infinitely variable between 0 and the rated device current reduces the failure probability of the braking device and thus indirectly that of the machines, too. An integrated overload monitoring function, which, if the braking frequency is too high, prevents motor restart, provides safety both for the VersiBrake and the operator. The integrated and adaptable motor standstill detection gives the user flexibility with regard to the motor types available.
These expansion modules fits into the integrated ac servo motors MAC50, MAC95, MAC140, MAC141 and MAC750 to adapt the motor to a specific application. This is a cost-saving approach as you only pay for what you need.
The unique module concept:
There are now modules for:
• Profibus-DP
• CANopen DS301/402
• Devicenet
• Nano PLC SUPPLIERS
• High speed 230kbit serial
RS485
•Wireless Bluetooth and WLAN
With D-sub industrial connectors, manufacturers of cable glands or M12 connectors.
Modules can also be developed to customer specifications.
•Measurement of rpm (non-contact and mechanical), speeds and lengths
•Storage of mean/min./max. values, last reading
•Battery check “Low Batt”
•Robust design with SoftCase (protective cover)
The DSW3 type speed and standstill monitor can be used in apllications requiring monitoring of rotational movements.
The fully digital and microprocessor controlled device professional monitors rotational speed pulses and signals a fault via 1 of 2 floating change over contacts.
Using a 4 digit LED display the user can set 7 parameters e.g. upper and upper and lower pulse limit values, the time between starting after powering-up and measurement start.
