Abstract
A control unit is configured to control driving of an actuator using an output of a rotary encoder having a rotator with a pattern row. The control unit includes a memory configured to store correcting information used to correct an arrangement error of the pattern row, and a controller configured to correct an output of the rotary encoder using the correcting information stored in the memory and to control driving of the actuator based on a corrected output of the rotary encoder.
Claims11
A control unit configured to control driving of an actuator using an output of a rotary encoder having a rotator with a pattern row, the control unit comprising:
- a memory configured to store correcting information used to correct an arrangement error of the pattern row;
- and
- a controller configured to correct an output of the rotary encoder using the correcting information stored in the memory and to control driving of the actuator based on a corrected output of the rotary encoder.
A device comprising:
- an actuator that drives a driven member;
- and
- a control unit configured to control driving of the actuator using an output of a rotary encoder having a rotator with a pattern row, the control unit including a memory configured to store correcting information used to correct an arrangement error of the pattern row, and a controller configured to correct an output of the rotary encoder using the correcting information stored in the memory and to control driving of the actuator based on a corrected output of the rotary encoder.
A control method for an actuator configured to control driving of an actuator using an output of a rotary encoder that includes a rotator with a pattern row, the control method comprising the steps of:
- acquiring correcting information used to correct an arrangement error of the pattern row;
- correcting an output of the rotary encoder using the correcting information;
- and
- controlling driving of the actuator based on a corrected output of the rotary encoder.
