Decentralised servo drive DIS-2

Decentralised servo drive DIS-2

The number of applications with decentralised servo drive technology is growing constantly and there is good reason for it. The decentralised servo drive DIS-2 provide a set of advantages that range from machine / automation system planning, machine / automation system assembly and commissioning to the use in the particular application.

The fully digital DIS-2 servo drive can be easily integrated into decentralised drive concepts at a favourable price. Its compact design allows direct mounting to the motor, which reduces the wiring to a minimum. Neither a control cabinet nor additional RFI suppression is required. They are controlled via I/O, RS232, or fieldbus. CANopen is available as a standard for all DIS-2 variants.

Alternatively, the DIS-2 FB can be provided with PROFIBUS or EtherCAT. Because of the shortest connection between the motor and servo drive, the wiring is minimised and a cabinet or additional EMC interference elimination are not necessary. Several DIS-2 FB can be economically networked by using two plugs for bus IN / bus OUT. The fieldbus is simply and directly cascaded from one DIS-2 FB to the next, which means that the connection neither needs long separate bus cables for every drive nor expensive T-switchpoints.
