Integrated materials handling drives

The SK 180E inverter series from Nord Drivesystems is well-suited for speed control of motors with up to 2.2 kW on horizontal conveyors.
The SK 200E series is available for higher performance and more demanding tasks up to 22 kW.
These inverters are the only units of their class to feature position control as well as interfaces for incremental and absolute encoders.
In this way, they allow for the use of standard asynchronous AC induction motors in applications requiring relative or absolute position control or synchronisation.
Hoist applications or safety-oriented applications can also be cost-efficiently implemented with these decentralised inverters: optional features include STO and ST1 safety functions up to SIL3.
For simpler applications where inverters are not required, such as horizontal conveyors without speed variation, the SK 135E electronic and wear-free motor starter ensures soft starts and reversing operation.
Users can set a boost voltage for a higher breakaway torque directly at the starter via DIP switches.
Integrated protection mechanisms for the input power (current limiting), the device (over-voltage and low voltage protection), the motor (PTC/I²t, motor phases), and the overall system (torque limiting, overload) render additional cabinet-mounted devices such as motor protection switches, reversing contactors and brake rectifiers unnecessary.
