Momentary Power Failures; Protection Of Power Supply And Output Sections - Panasonic AFPE224300 User Manual

3.6.2 Momentary power failures

Operation of momentary power failures
If the duration of the power failure is less than 10 ms, the FP-e unit continues to operate. If the power is
turned off for 10 ms or longer, operation changes depending on the combination of units, the power supply
voltage, and other factors. (In some cases, operation may be the same as that for a power supply reset.)

3.6.3 Protection of power supply and output sections

Power supply
An insulated power supply with an internal protective circuit should be used. The power supply for the
control unit operation is a non-insulated circuit, so if an incorrect voltage is directly applied, the internal
circuit may be damaged or destroyed. If using a power supply without a protective circuit, power should be
supplied through a protective element such as a fuse.
Protection of output
If current exceeding the rated control capacity is being supplied in the form of a motor lock current or a coil
shorting in an electromagnetic device, a protective element such as a fuse should be attached externally.
