An object of the present invention is to provide a drive control device for a drive system including a vertical carrier machine that makes effective use of regenerative power generated at a vertical carrier machine with a high proportion of regenerative operation. 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) mainly for regenerative operation, within an operating time during which maximum regenerative energy is generated, in series of operations by the electric motor (M1) mainly for regenerative operation. |
