The SmartServo drive series follows the tradition of Metronix to provide a simple to integrate, user friendly solution to even the most demanding servo applications. This starts with the compact drive housings that include many of the ancillary components necessary in other systems to meet CE compliance. This includes mains filters, line and motor chokes, and regen / brake resistors.
The drives feature the Metronix Universal Encoder Interface (UEI), allowing the use of most available encoder systems. Furthermore, the smartServo drives incorporate a number of communication and Fieldbus interfaces, built in to the drive.
Numerous integrated software functions make the smartServo BL-4000-C servo drives real all-rounders in drive technology.
The smartServo BL-4000-C servo drives not only support numerous motor types and all common position encoders directly, but also can be adapted very flexible to a variety of applications via simple parameterisation of the integrated technology functions. The high-precise evaluation of external signals in the drive allows shortest possible cycle times.
Positioning
Whether linear, jerk-limited or torque-limited: With the integrated positioning control every motion task can be easily realised.
Path program / Linking
All 256 positioning sets can be linked to solve complex positioning tasks without external control system. Furthermore, digital inputs allow situation-related branching.
Flying saw
By integrating a „flying saw“ into the drive, not only short cycle times, but also extremely high accuracies can be reached.
Electronic gear/ Synchronisation
The position-synchronous or speed- synchronous motion of various drives with variable gear ratios can be quickly parameterised via the software assistant
Linear motors
Special procedures for the determination of the commutation position and corresponding monitoring functions allow the operation of linear motors without commutation information.
Rotary table
For rotary table applications, several rotary axis modes are available. These can be combined with the cam disk and with the electronic gear.
Switching cams
Position trigger, rotor position trigger and switching cams in connection with the cam disk can be easily parametrised and connected to digital outputs.
Universal encoder interface
The smartServo family of drives can operate with rotary, linear and torque motors alike. Suitable feedback devices include, Resolver, Incremental Encoder, SinCos encoder (single-/ multiturn) with Hiperface, high resolution encoders as well as single-/ multiturn absolute encoder with EnDat interface.
