摘要： A motor controller, operatively connected to a motor having an output shaft, includes a rotary detector to detect a rotation direction and a rotation amount of the output shaft of the motor to generate an actual rotary signal, a drive controller to generate a control signal based on the actual rotary signal and a target rotary signal indicating a target rotary direction and a target rotary amount, and a driver to supply a driving power to the motor based on the control signal. When the motor is in a hold state, the control signal is reversed periodically for a predetermined reverse time period T2 per a predetermined one reverse cycle T1. When the control signal is not reversed for a certain lock detection time period Tr that is longer than the revere cycle T1 of the control signal, supply of the driving power to the motor is blocked.

摘要： A management apparatus for managing one or more devices includes circuitry to: acquire information indicating a use history of a device for each predetermined period; calculate, based on the acquired information indicating the use history, a predicted value indicating operation timing at which an operation is performed on the device; and output, based on the predicted value, an output value for the predetermined period. When an output value that is output for an (N−1)-th time is greater than a threshold, the circuitry outputs, as an N-th-time output value, the predicted value that is calculated for an N-th time. When the output value that is output for the (N−1)-th time is less than or equal to the threshold, the circuitry outputs, as the N-th-time output value, a value that is smaller than or equal to the output value that is output for the (N−1)-th time.
