Besides the emergency stop input from the NC controller, double-protection when an emergency stop occurs can be
provided by directly inputting an external emergency stop to the drive unit. Even if the emergency stop is not input from
NC for some reason, the contactors can be shut off by the external emergency stop input.
Outlines are shown below. For more details, refer to the Instruction Manual of each drive unit.
