<p>In an elevator device, a drive means has a drive sheave, a motor for rotating the drive sheave, and a motor drive section for driving the motor. The motor drive section is controlled by a control means. While an elevator car travels, the control means monitors a load on at least one device in the drive means, and the control means creates, according to conditions of the load, a control instruction on the traveling speed of the elevator car and outputs the result to the motor drive section.</p> |
