Claims63
A vibration-type drive apparatus comprising:
- a control unit that outputs a command signal;
- a drive unit that outputs a drive signal in accordance with the command signal;
- a vibrator unit made up of two or more vibrators that vibrate in accordance with the drive signal;
- a drive signal analyzing unit that analyzes the drive signal and outputs an analysis result;
- and
- a determining unit that determines whether there is a break in wiring lines respectively coupled to the vibrators in accordance with the analysis result.
A control method for a vibration-type drive apparatus, the control method comprising outputting, by a control unit, a command signal to a drive unit to cause a vibrator unit made up of two or more vibrators to vibrate by using a drive signal output from the drive unit in accordance with the command signal, and analyzing the drive signal and outputting an analysis result to determine whether there is a break in wiring lines respectively coupled to the vibrators in accordance with the analysis result.
