Product description
The Control Techniques SP0402 belongs to the universal Unidrive SP platform for demanding motor-control duties in machines and production systems. This compact frame-size 0 unit operates from a three-phase 380–480 V supply and provides a maximum continuous current of 1.7 A with a peak current of 2.9 A. Control Techniques assigns this version a typical motor rating of 0.55 kW or 0.75 hp. It is particularly suitable for smaller conveying, positioning, winding and auxiliary axes where an existing Unidrive SP configuration needs to be retained. The platform supports both open-loop operation and closed-loop speed or position control. In open-loop operation, the documented output frequency extends to 3,000 Hz; in closed-loop operation, speed commands up to 40,000 min⁻¹ are supported. A frequency resolution of 0.001 Hz and accuracy of ±0.01 percent of full scale allow finely tuned motion sequences. A two-wire RS485 interface with Modbus RTU or ANSI protocol is available for integration into control architectures. The standard dynamic braking transistor simplifies connection of a suitable braking resistor for short regenerative load cycles. As a frame-size 0 drive, the SP0402 accepts two SM option modules and can therefore be adapted to feedback, communications or additional I/O requirements. For a like-for-like replacement, the complete SP0402 model code, supply class, motor current, installed option modules, feedback device, braking resistor and parameter set must match the existing machine. Motor connections, protection concept and stored drive parameters should also be checked against the machine documentation before commissioning. This supports targeted repair of an established Unidrive SP system without unnecessary changes to the proven machine architecture.

What is the Control Techniques SP0402 used for?
The SP0402 controls smaller AC and servo motors in machine axes. It supports open-loop and closed-loop methods and is designed for three-phase 380–480-V drive systems.
What must be checked when replacing an SP0402?
Check the complete SP0402 model code, supply voltage, motor current, feedback device, option modules, braking resistor, terminal assignment and the existing parameter set.
Is there a guarantee?
Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.
Please note that the guarantee only applies when the warranty seal is undamaged.
If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.
Further details are provided in the terms and conditions supplied with your quotation.
How quickly do you dispatch and which shipping options are available?
We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.
Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.
We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.
Which payment methods are available?
Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.
As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.
Can we return items if they were ordered incorrectly?
Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.
Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.
Is there a discount when ordering several items?
For larger order quantities or several items of one type, we can offer individual discounts.
Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.
Do you also purchase industrial spare parts?
Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.
The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
