5.6 Safety Measures

5.6.2
Momentary Power Failures
Operation of momentary power failures
If the duration of the power failure is less than 4 ms, the FP
Σ
continues to operate. If
the power is off for 4 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.)
5.6.3
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.
