A1.6.3 Configuration of the armature current feedback circuit
Overview
The current feedback signal is sent to the control unit by two current transducers (CT) inserted on phases U and
W of the controlled power bridge. It is rectified on the FIRXP-XX card by a three-phase diode bridge and ap
-
plied to a burden resistor that converts it into a voltage signal proportional to the DC motor current value. This
is then applied to the armature current regulator which compares it with the reference value.
The standard FIRXP-XX card offers a choice of two burden resistor (RB) values, 2.5 Ohm or 5 Ohm, which
are suitable in the majority of cases. Otherwise an external burden resistor can be used, connected between
terminals RCT and 0VI.
In order to enable precise adjustment to the many possible rated current values (size of the controlled power
bridge), a programmable gain amplifier (N8) is inserted between the burden resistor and the current regulator.
The gain is set by means of a 12-bit binary number selected with dip-switches S3 and S4.
