Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a drive control device for a drive system including a vertical conveyer in which regenerative electric power generated in the vertical conveyer of a high regenerative operation ratio can be effectively utilized.SOLUTION: A drive control device A for a motor M1 mainly for regeneration, a drive control device B for a motor M2 mainly for power run and a regenerative electric power storage capacitor 12 are provided. The regenerative electric power storage capacitor 12 is connected between a positive electrode terminal P11 and a negative electrode terminal N1 of a DC output line of a converter 1 in a first inverter INV1 of the drive control device A via a third inrush current suppression circuit 11 connecting a third resistor R3 and a switch SW3 in parallel. The capacitor 12 includes such electrostatic capacitance and DC internal resistance as to generate braking torque required for speed control of the motor M1 mainly for regeneration with a charging current which flows when charging regenerative energy generated by the motor M1 mainly for regeneration within an operation time generated by maximum regenerative energy among a series of operations of the motor M1 mainly for regeneration.
