Overload characteristics are shown in the following table. If, for example, a current of three times the
Servomotor’s rated current flows continuously, it will be detected after approximately five seconds.
Note 1. The load ratio is the ratio of the motor current to the rated motor current as a percentage.
Note 2. For example, if a current of three times the rated motor current flows continuously, an over-
An overload protection (electron thermal) function is built into the Servo Driver to
protect against Servo Driver or Servomotor overload. If an overload (A.70) does occur,
first clear the cause of the error and then wait at least one minute for the Servomotor
temperature to drop before turning on the power again. If the power is turned on again
too soon, the Servomotor coil may be damaged.
