More Information
Summary:An insertion apparatus includes an insertion section, a motor that rotates a rotational housing, a drive control unit that supplies a driving current to the motor to control driving of the motor, a driving current detector that detects the driving current flowing through the motor, a torque limit value storage unit that stores a torque limit value, a temperature detector detects a temperature of the rotational housing, a temperature measurement unit that measures a temperature in a vicinity of the rotational housing based on a detection result obtained from the temperature detector, and a torque limit value correction unit that corrects the torque limit value in accordance with the temperature measured by the temperature measurement unit.
