<<Precautions for using regenerative brakes>>
1) When using the regenerative brakes, set the parameter P18 setting data
to "0". The brakes will not operate when the default data "1" is set.
2) Always use the Matsushita-dedicated option for the brake resistor.
Refer to the precautions on page 15 for installing the brake resistor, etc.
3) The regenerative brake specifications are shown below. Always consider
the working conditions carefully before using.
Note that the inverter could be damaged if the specifications are
exceeded during use.
·
Maximum duty factor (%ED) : 2%
·
Maximum working time
: 3 seconds
·
Maximum torque
: 100%
Always connect protective devices such as fuse for overcurrent, short circuits
and leakage protection to the input.
