Provided is a control system for elevators which ensures safety and allows a reduction in convenience to be suppressed even if the braking torque of a braking device is reduced. The control system is for elevators which are equipped with a car (2), a hoisting machine (4), a braking device (7), and a buffer (6) provided in the interior of a hoistway (1). The control system is equipped with: a travel distance detection unit (12c) which detects the distance the car (2) travels before coming to a stop after the braking device (7) applies the brakes to the hoisting machine (4); and an adjustment unit (12f) which adjusts, according to the distance the car (2) travels before coming to a stop detected by the travel distance detection unit (12c), the monitoring position or monitoring speed for starting the emergency stop of the car (2) during the operation of an elevator, so that at the time of an emergency stop of the car (2), the speed of collision of the car (2) with the buffer (6) becomes an allowable speed.
