512C Series Converter
Chapter 1 GETTING STARTED
Introduction
The 512C converter is intended for use in an Industrial Environment, it should be mounted
within an enclosure which provides protection to the converter and the user.
The converter should be permanently earthed at the terminals provided.
The 512C converter is suitable for the control of Permanent Magnet and Shunt Wound DC
Motors.
The converters are designed to operate from a single phase ac mains supply in the range of
110Vac to 415Vac at 50 or 60Hz. A simple transformer tap arrangement allows the converter to
be programmed to suit the applied voltage.
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
selectable.
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.
Converter protection is provided by a Instantaneous Overcurrent trip circuit overriding control in
the event of a Short Circuit.

Recommendations
Although the controller is designed to provide double or reinforced insulation between the
user and bare live parts, it is recommended that the “0v/Signal Ground” is earthed. Where a
number of controllers are used in a system the “0v/Signal Ground” terminals should be
connected together and earthed at one point.
The controller is designed for armature current form factor of 1.5 or less. It is recommended
that an armature choke be fitted where a form factor of less than 1.5 current cannot be
guaranteed.
Due to the earth leakage currents the controller and filter should be permanently earthed.
This can be achieved by either connecting two earthing conductors of the required value, see
table 11.1, or connecting one earthing conductor of at least 10mm2.
IMPORTANT: The Converter fitted with an internal or external ac supply EMC filter is only suitable for
earth referenced supplies (TN).

When the mains voltage is non-standard, i.e. not selectable via the transformer tapping link
(380/415V, 220/240V or 110/120V), connect a low power Autotransformer to generate a
standard voltage. Connect the output of the Autotransformer to the AUX terminal. Move the
Supply Selector from "MAINS" to "AUX". Select the appropriate voltage via the transformer
tapping link. The Autotransformer must be connected to the same phase as the incoming
power to provide correct coding to the controller.

It is recommended that the “0V/common” be connected to protective earth/ground for safety
reasons. In a system comprising of more than one controller, the “0V/common” signals
should be connected together and joined to protective earth/ground at one point only.

Operating the Converter 4-4
512C Series Converter
Basic Setting-Up Procedure
Caution
BEFORE ATTEMPTING TO CONNECT POWER
Controller
Check:-
the Main power supply voltage is within the operating range of the controller.
the Armature voltage and current ratings are compatible with controller supplied.
the Field voltage and current ratings are suitable.
All external wiring circuits are correct, i.e:-
Power connections
Control connections
Motor connections
Note: Completely disconnect the controller before point to point checking with a buzzer or
when checking insulation with a megger.
For damage to equipment.
For loose ends, clippings, drilling swarf etc., lodged in the drive or ancillary equipment.
Motor
Inspect the motor, in particular the commutator for any extraneous matter. If an air supply is
available, it is recommended to blow over the commutator.
Check the brushes are properly seated and that the brush spring tension is adequate.
If possible check that the motor (and vent fan if fitted) can be turned freely by hand.
Preparation
Machine
Check:-
That rotation of the motor in either direction will not cause damage.
That nobody else is working on another part of the equipment that will be affected by
powering up.
That other equipment will not be adversely affected by powering up.
Controller
Prevent application of the main power supply by removal of the supply fuses.
Disconnect the load from the motor shaft if possible.
If there is any doubt as to the integrity of a particular installation, insert a high wattage
resistor (i.e. fire bar elements) in series with the motor armature.
If it is possible to rotate the motor, and tachogenerator feedback is in use, check that forward
rotation results in positive tacho feedback, i.e. terminal 1 is positive with respect to terminal
8 or 11.
