∗1 Maximum static torque at excitation is the maximum static torque at the rated motor current, modified in consideration of
permissible strength to the gears.
The value is reduced to approximately 50% by the current-cutback function when the motor operates in combination with a
dedicated driver.
∗2 The rotational directions of the motor shaft and gear output shaft will vary according to the gear ratio.
Same direction as the motor: Gear ratios 3.6:1, 7.2:1 and 10:1
Direction opposite the motor: Gear ratios 20:1 and 30:1
∗3 Permissible torque represents the limit of the gears' mechanical strength. Keep all loading, including acceleration torque, below
the limit of torque.
∗4 The value for the driver's power-supply input current represents the maximum input current, which varies with pulse speed.
∗5 These are specifications for the electromagnetic-brake type only.
∗6 The figures in parentheses [ ] are specifications for the electromagnetic-brake type.
