590+ Series DC Digital Converter
is a relay which can be operated in exceptional circumstances where human safety is of
paramount importance.
•
Terminal B8 (Program Stop) provides a facility for regenerative braking on a 4 Quadrant
drive (590+).
Zero Speed, Drive Healthy, Drive Ready (B5, B6, B7)
These digital output terminals provide a +24V dc output signal under
certain conditions. This allows for the connection of relays which, in
conjunction with the Enable, Start/Run and Emergency Stop relay, can
be used to enhance the safe starting and stopping of the controller.
These are configurable outputs and can be used as required in the
control system design, i.e. cubicle door lamps, connection to a suitable
PLC.
(The diagram shows a simple default configuration).
Analog Tachometer (G1, G2, G3, G4)
Refer to Chapter 13: “Standard and Optional Equipment” - Optional
Equipment for further information.
An Analog Tachometer is connected to the Converter using a screened
twisted pair cable throughout its entire length to provide speed feedback
via the Tacho Calibration Option Board. This provides facility for an
AC or DC tachometer. The screen is grounded or earthed only at the
drive end, any other grounding arrangement may cause problems.
Terminals G1 & G2 are for AC tacho connections.
Terminals G3 & G4 are for DC tacho connections.
Note:
The speed loop is set-up for an analog tacho by the SPEED FBK
SELECT parameter in the SPEED LOOP function block. Select
ANALOG TACH for this parameter.
If an AC tachogenerator is used the output is rectified to
produce the dc feedback to the speed loop. Consequently, the
controller can only be used with a positive setpoint.
Refer to Chapter 4: “Operating the Converter” for set-up information.
External Trip (C1, C2)
Terminals C1 and C2 must be linked if an External Trip interlock is not
required.
This input terminal provides an external trip facility to any normally-closed
trip switch , e.g. for vent fan overload protection.
