Digitax ST-I

servo drives for pulse duty servo applications requiring high peak torque

Digitax ST-I (Indexer)

1.7 A – 8.0 A rms (5.1 A – 24 V Peak)

230 V | 460 V

Digitax ST-I servo drives are optimized for pulse duty servo applications requiring high peak torque (up to 300% peak), dynamic response, ease of use and flexible integration features.

The Digitax ST-I is an ideal solution for point-to-point positioning applications.

  • Features

    The Indexer model is designed for simple standalone positioning applications using an onboard position controller. Programming is achieved using a flexible IEC61131-3 software environment including PLCOpen Function Blocks, Fieldbus, Ethernet and I/O enable connectivity to other automation components.

    Applications include: Indexing tables, fast conveyor positioning, cut-to-length machines, punching.
