Parker SSD Drives 514C – 32A Four Quadrant DC Thyristor Drive

The 514C controller is intended for use in an Industrial Environment, it should be mounted
within an enclosure which provides protection to the controller and the user.

The controller should be permanently earthed at the terminals provided.

The 514C controller is designed to control the speed of a DC Shunt wound or permanent
magnet motor. It will provide control of the motor speed in all 4 Quadrants of operation.
The controllers are designed to operate from a single phase AC mains supply in the range of 110 Vac to 415 Vac at 50 or 60 Hz. An auxiliary supply is required for internal power supply generation and main supply contactor sequencing. Coding is derived from the main power terminals and is functional over the whole input voltage range.

The Speed of the DC Motor is controlled using a linear closed loop system with a feedback
signal from either tachogenerator or armature voltage, the feedback source being switch

A current loop within the speed loop always ensures that controlled levels of current are
applied to the motor, actual levels being scaleable via programmable switches.

Motor protection is provided by a Stall detection circuit which will remove current from the
motor after approximately 60 seconds.

Controller protection is provided by a Instantaneous Overcurrent trip circuit overriding
control in the event of a Short Circuit

The 514C offers full four quadrant regenerative control of
permanent magnet or wound field DC motors. Ideal for
applications requiring accurate or rapid deceleration of
high inertia loads. Effective for single or multiple motor
applications to 32A, 9kW.
Typical applications include:
• Machine tool spindles
• Wire drawing machines
• Winders/Reelers

If you want to see how your machine or process is operating day in day out from anywhere in the world, where do you start? With the increased risk of hacking of industrial devices becoming ever more prevalent Security Week – New Vulnerabilities Can Allow Hackers to Remotely Crash Siemens PLCs it’s not as simple as just hooking your PLC onto your local network.

An increasing number of companies are turning to remote cloud-based solutions for machine monitoring. Optima are pleased to offer the Cloud-based solution which keeps your automation hardware safely behind a secure firewall. Most of our clients prefer a SIM-card based system. The benefits of this system are that the equipment is always live whenever there is cellular reception available. Our range of antenna options mean that reception is possible even in the most remote locations.

The video below shows a basic demonstration dashboard. If you would like to know more then please get in touch – we like to talk!

This video gives a very brief demonstration on how our Remote Access and Cloud Logging System can help you keep track of how your machine is performing. See when the machine is started, stopped, realise production metric data straight to your mobile, desktop or tablet.

We have been trialling our remote machine data dashboards #iot #industry4. These allow real-time data to be visualised from any PLC anywhere in the world to a PC, tablet or mobile ‘phone anywhere in the world! The system can communicate over 4G, Wi-Fi, or a direct Ethernet connection. From Kazakhstan (yes, we do have two units out there!) to Kendal (we haven’t got one there yet…), we have you covered for a very low monthly cost.
Our remote reporting dashboards which can send #production #reports by #email will shortly be ready for release.
