Siemens Drives

 

Our 18.5kW Drive Package

Optima are one of only 7 official Drives & Motion Integration partners in the UK for Siemens. Optima’s expertise in high-speed, complex variable speed drive and motion applications combined with one of the largest integrated automation providers in the UK gives our customers excellent machine control combined with the worldwide backup and support of Siemens.

From low to high power ratings and medium to high-performance drives, Optima can integrate the entire low voltage range of AC asynchronous, synchronous and servo drives to meet any demanding application.

Below you will find details on the full range of Siemens drives we supply and install on our applications.

V20

The SINAMICS V20 is a range of inverters designed for controlling the speed of three phase asynchronous motors in low-performance fan/pump applications. The drive comes with a range of macros that provide a set of parameter settings for a specific application. These can be used in simple pump or fan applications, compressors or conveyors. Other features include the ability to perform a flying start on already running motors with a heavy inertia load so that the motor runs up to the setpoint without causing damage to the equipment. The drive also features an integrated PID controller to support all kinds of simple process control tasks, e.g. controlling pressures, levels, or flow rates. We would recommend commissioning these drives with the V20 Smart Access module. This greatly simplifies setting up the drive from your smartphone. No more trawling through endless parameter lists. It’s a great little piece of kit and should be in every drive commissioning engineers’ toolkit. SINAMICS_V20-Smart_Access-Flyer

V90

The V90 is an excellent little servo drive. It combines a perfectly-matched motor and drive combination to meet medium-to-high demand position control tasks. It can be used in high-speed motion drives, but also due to it’s competitive cost and ease of integration can be used to modernise slitting and winding machines that traditionally used permanent magnet DC Motors and simple DC Drives. When coupled with a Siemens S7-1200 PLC and HMI on PROFINET the integration options become very attractive indeed. They are one of our favourites here at Optima.

Supply of Motor Generator Test Rigs to Blackpool & The Fylde College

AC and DC Motor Test Rig 1

If you want to learn about Asynchronous and Synchronous AC machines, DC Motors, Generator and Motor principles it’s useful to be able to carry out practical work on them.

Step forward Optima who helped Blackpool & The Fylde College fulfil their requirements to have two new state-of-the art installed at their brand new training facility near Fleetwood

Challenges

There were a number of key challenges in the design. On Test Rig 1, the AC Motor would operate in two modes:

  • Prime mover, with the load being applied by the DC motor.
  • Generator mode with the DC motor driving the AC motor.
Synchronisation Meter

When acting as a generator, the AC motor would have to be synchronised to the mains supply before being “switched-in”. This is to simulate a real-world situation on-board ships where back-up generators may have to be manually switched-in.

Design

The panel design incorporated banana type sockets to facilitate the ease of connection of external measuring instruments such as power meters.

The panels incorporated a host of instrumentation to afford total visibility. These included:

  • Machine torque
  • DC Armature Current
  • DC Armature Voltage
  • Single Phase Mains Voltage L-N
  • Single Phase Alternator Current
  • Single Phase Alternator Voltage L-N
  • Alternator Excitation Current

Test Rig 2

Test Rig 2 incorporated the very latest Siemens PM250 Regenerative Power Module and a Soft Starter to the test rig AC Motor. The user has the option to switch between the two. A DC Motor acts either as a prime mover or generator giving ultimate flexibility in operation.

The incorporation of a regenerative AC solution brings the very latest in cutting-edge drive architecture to an educational establishment. There aren’t many drive manufacturers who can supply lower-power regenerative modules.

Overall, the test rig projects were a great success combining the College’s and Optima’s knowledge to product test rigs that will serve students well for many years to come.
