An apparatus and method for operational control of a reciprocating motor compressor, includes performing an operation of the reciprocating motor compressor precisely and accurately. In addition, with the above apparatus and method, the phase difference between a first speed value of the motor (or first TDC value) and current applied to the motor is detected, the second speed value of the motor at the inflection point of the detected phase value (or second TDC value) is detected and stored as a reference value, and the speed of the motor is controlled on the basis of the reference value and the first speed value of the motor (or the first TDC value).
