At start-up, a small amount of
current is allowed.

As the load increases during
fastening, so does the amountof current allowed.

When the current amount goes up
to the optimum value configured
from a preset torque, current flow
is cut off to stop the motor.

SOFT fastening setting

HARD fastening setting

Suitable for workpieces with high fastening load such as
tapping screws or fastening soft objects such as rubber.

Suitable for workpieces with small fastening load such as
threaded holes or rigid bodies such as metal.

A program that seats the screw at the auto-configured optimum
rotation speed based on the torque percentage after the initial

When the Channel Pattern is switched, the Channel is also switched, so the responses are sent continuously.

Since control is performed even when communication between the controller and PC or sequencer fails, use this function
when you wish to maintain the reliability of transmission and reception. This command transmission is not included in theten commands that are stored.
