The drive device comprises a DC bus (2A, 2B), a motor bridge (3) connected to the DC bus for the elec­ tricity supply of the elevator motor (6), which motor bridge (3) comprises high-side (4A) and low-side (4B) switches for supplying electric power from the DC bus (2 A, 2B) to the elevator motor (6) when driving with the elevator motor (6), and also from the elevator motor (6) to the DC bus (2A, 2B) when braking with the elevator motor (6), a control circuit (5) of the motor bridge, with which control circuit the opera­ tion of the motor bridge (3) is controlled by producing con­ trol pulses in the control poles of the high-side (4A) and low-side (4B) switches of the motor bridge, brake a control­ ler (7). which comprises a switch (8A, 8B) for supplying electric power, to the control coil (10) of an electromagnetic brake (9), a brake control circuit (11), with which the opera­ tion of the brake controller (7) is controlled by producing control, pulses in the control pole of the switch (8 A, 8B) of the brake controller, an input circuit (12) for the safety signal (13) to be disconnected/connected from outside the drive device, drive prevention logic (15), which connected is to the input circuit (12) and configured is to prevent the passage of control pulses to the control poles of the high- side (4 A) and/or Jow-side (4B) switches of the motor bridge when the safety signal (13) is disconnected, and also brake drop-out logic (16), which connected is to the input circuit (12) and is configured to prevent passage of the control pulses to the control pole of the switch (8A, 8B) of the brake controller when the safety signal (13) is disconnected.
