[Application]

The regeneration discharge unit is designed to absorb excess energy generated in an actuator (or axis) motor during deceleration. The unit is useful when load inertia exceeds the tolerance, or when a heavy load is descended along the Z-axis over a long stroke (generating excessive electricity). (The unit prevents overvoltage generated in the controller.)

* All discharge energy is converted into heat.

* If the discharge circuit of the regeneration discharge unit has overheated, it is signaled by contact output (N.C).

* One unit is needed per axis, and can be connected to the master or slave unit when necessary.

| Cooling fan

A cooling fan is attached to ABSIM000 alone.

• A thermal relay which operates at the temperature of 150°C is incorporated in the discharge resistor of the regeneration discharge unit.

• When this relay has operated, output terminals C1 to C2 of the regeneration discharge unit is set open.

• Program a sequence so that the controller power is always turned off when the thermal relay has operated.
