Title: Recording medium carrier device and its controlling method
Inventor: SASAKI TAKASHI
IPC: G05D3/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To automatically manage maintenance time by allowing a host to grasp the travel distance (revolution) of each motor of a transferring part and the number of brake control times. SOLUTION: A transfer control substrate 20 is provided with a motor speed controlling part 25, an encoder pulse counter 26 and a brake controlling part. When a macro command is issued from a host controller, the part 25 outputs a speed command value, turns off the brake of a motor and also controls the motor M with current control by a servo driver 29. An encoder pulse for position detection of the motor has a pulse given to the driver 29 and the counter 26, the counter 26 counts pulses, and a CPU 21 calculates the travel distance (revolution) of the motor, manages the position of the motor and also transfers it to the host. Also, when the macro command is finished, the brake controlling part 27 brakes the motor and also eliminates current of the motor. The CPU 21 counts the number of brake execution times and transmits it to the host.
