ELEVATOR APPARATUS
摘要:
In an elevator apparatus, a brake device stops a car from running. The brake device has a power shutoff portion for shutting off a supply of power to a brake opening coil in response to a brake actuation command, and a current adjusting portion for supplying the brake opening coil with power while adjusting an amount of current in response to a deceleration reduction command from a brake control portion. The current adjusting portion can supply the brake opening coil with power even when the supply of power to the brake opening coil is shut off by the power shutoff portion.
