Title:
Printing device
Document Type and Number:
Japanese Patent JP6320036
Kind Code:
B2
Abstract:
A motor control method performed by a controller includes monitoring a motor load of at least one of a plurality of motors including a first motor and a second motor driven by one common power source having a protection circuit, wherein the protection circuit is operated to shut down the power source in a case where a current value of the power source continues to exceed a threshold during a period Tg, and stopping motor drive in a case where the monitored motor load continues to exceed the threshold during a period Tn, which is shorter than the period Tg. In addition, monitoring of the motor load is skipped during acceleration operations of the first motor and the second motor when both the first motor and the second motor are driven, and then monitoring of the motor load is restarted.
