12. BACK-FEEDING LOADS
Loads such as decelerating motors and inductors can feed voltage back to the PISA11 protection module. This feature
is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).
The protection module is resistant and does not show malfunctioning when a load feeds back voltage up to 30Vdc to
the protection module. It does not matter whether the protection module is on or off.
The protection module has no capability to absorb energy. Internal diodes (integrated body diodes of the Mosfets)
directs the voltage and energy to the power supply, which is connected on the input side of the protection module.
The power supply defines the amount of energy which can be absorbed.
