Operation with the S-KG control unit (optional)
The S-KG control unit is a compact 4-Q DC servoamplifier for speed set of
brushed DC motors with a current consumption of up to 0.5 A. The operating
parameters of this control unit are specially adapted to the micro annular gear
pumps mzr-2521 and mzr-2921 of the low pressure series manufactured by
HNP Mikrosysteme. The S-KG motor control unit based on a high capacity 16-Bit
microcontroller, which may be precisely adjusted also at low motor speeds.
A set of inputs and outputs enable the user to adjust the motor control such as
the nominal value input, the sense of rotation input, enable input, error output
and speed signal output.
At the delivery the parameters of the control unit S-KG-21 are preset for
operation with the micro annular gear pumps mzr-2521 and mzr-2921. Also the
analog nominal value input of the control unit is by default preset for the
potentiometer operation mode.
