Does a stepper motor need a motor driver?

Yes, a stepper motor requires a driver to control its phases and current. The TPM SVR-K112 is a closed-loop stepper driver that supplies up to 4.2A per phase to 2-phase bipolar stepper motors and adds encoder feedback for real-time position correction.

What is a driver for a stepper motor?

A stepper motor driver is a controller that energizes the motor's phases in the correct sequence and magnitude to produce motion. The TPM SVR-K112 does this while monitoring encoder feedback to detect and correct position errors automatically.

Can I run a stepper motor without a driver?

No, a stepper motor cannot run without a driver because it has no brushes to commutate current on its own. The TPM SVR-K112 provides the necessary phase switching, current control at 4.2A per phase, and closed-loop feedback for accurate positioning.

What is the maximum current for the TPM SVR-K112?

The TPM SVR-K112 delivers a maximum phase current of 4.2A per phase to drive 2-phase bipolar stepper motors in industrial automation systems.

How do I set up the TPM SVR-K112 on an EtherCAT network?

The TPM SVR-K112 uses onboard DIP switches for EtherCAT address configuration without requiring software tools. The driver connects to an EtherCAT network delivering 100 Mbps deterministic control and mounts in a compact 74 mm x 140 mm x 31 mm form factor on panel or DIN rail.

Does the TPM SVR-K112 correct positioning errors?

Yes, the TPM SVR-K112 uses encoder feedback to monitor motor position in real time and automatically correct errors, providing closed-loop control that conventional open-loop stepper drivers cannot match.

Closed-loop EtherCAT stepper drive vs. open-loop stepper controllers:

The TPM SVR-K112 combines encoder feedback with networked control, making it the choice when position accuracy and real-time error correction matter more than simplicity. Open-loop steppers work well for basic positioning, but this driver adds closed-loop verification and deterministic 100 Mbps EtherCAT synchronisation across multiple axes.

For applications where missed steps or load variations cause position drift, encoder feedback automatically corrects errors without stopping the axis.
On distributed multi-axis machines, EtherCAT networking coordinates motion across separate drivers with 100 Mbps deterministic timing, eliminating sync delays between axes.
In confined or panel-mount spaces, the 74 mm x 140 mm x 31 mm body and DIP switch configuration simplify integration without custom software setup.
When driving standard 2-phase bipolar steppers up to 4.2A per phase, this controller suits medium-torque automation tasks like precision indexing, labelling, and material handling on shared industrial networks.
