SERVO DRIVES AND SERVO MOTORS

NCT

servo drives

The NCT servo drives are complete EtherCAT peripheries.

They are connected to NCT 200 control central unit (EHU)

by one EtherCAT bus. Moving commands are received and

also absolute position transmitted to CNC software by using

this wide-frequency channel. NCT servo drives are devel-

oped especially for machine tool applications. The NCT

servo drives are the essential peripheries of the NCT controls

due to their extremely fast and accurate current and speed

regulation capabilities.

SoE SERCOS over EtherCAT

The NCT control communicates with servo drives by a widely

used standard protocol. Using servo drives of several manu-

facturers is possible because of standard connection. Setting

servo drives is done from NCT control easily, without external

device. The tested parameters are saved in control. The con-

trol loads the parameters into each servo drive every time

when it is switched on, so the parameter setting is automatic

also in case of changing motor or servo drive.

Parameter setting

Servo drives

The NCT servo drives are connected to NCT control by using

standard SoE (SERCOS over EtherCAT) or CoE (CAN OPEN

over EtherCAT) protocol, so servo drive parameters can be

loaded from control. Parameter sets of servomotors and servo

drives saved in HDD of the control. In case of starting up a

system consisting of control and servo drives or changing a

servo drive the assigned parameters are loaded immediately

and the servo drives will be ready for operation. There are

ready, tested parameter sets for all NCT synchronous servo-

motors in HDD of NCT 200 controls for our users.

NCT motors

Developing NCT servomotors is one of the most successful,

most effective developments of our R&D department. The

NCT A, Ai, AiS, AMS and TORQUE motors also satisfy the

highest demands. The mechanical construction, size, speed,

and electric parameters of our motors are developed espe-

cially for machine tool applications. However, the Ai motors

are mounted with EnDat 2.2 absolute rotary encoders as stan-

dard, each NCT servomotor is available with incremental TTL

or sinusoidal output (SINCOS/1Vpp) measuring system as

option.
