Zusammenfassung:	The drive control device for a drive system including a vertical carrier machine includes: a drive control device (A) for an electric motor (M1) mainly for regenerative operation; a drive control device (B) for an electric motor (M2) mainly for power operation; and a regenerative power storage capacitor (12) that is connected between a positive terminal (P11) and a negative terminal (N1) of a direct-current output line of a converter part (1) via a third inrush current suppression circuit (11) in which a third resistor (R3) and a switch (SW3) are connected in parallel, wherein the capacitor (12) has an electrostatic capacitance and a direct-current internal resistance to produce a current value with which braking torque required for velocity control of the electric motor (M1) mainly for regenerative operation is generated by a charging current flowing at storage of the regenerative energy generated by the electric motor (M1).
