Panasonic VF100 - P087: PWM Frequency Signal Select

P087： PWM frequency signal select
Using PWM signal from PLC etc. to control operation frequency.
(But allowable PWM signal cycle is within 0.9ms~1100ms )
＊When selecting PWM frequency signal, function of
SW4 (terminal No.7) and SW5 (terminal No.8) are
forced to be used by PWM control exclusively.
[Connection and function descriptions of control circuit terminals]
PWM signal
・ Terminal No.7: frequency signal changeover input

・ Terminal No.8: PWM frequency signal input terminal
SW4
ON: signal set with parameter P004
OFF: PWM frequency signal
Input open-collector signal that meets the specifications
below.
Max. rated voltage: 50V DC
Current: 50mA or more

・ When parameter P005 is set to "50", the max. output frequency is "50Hz". When set to "60",
the max. output frequency is "60Hz". When set to "FF" or "3C", the max. output frequency is
"value of parameter P008".

Note
・Allowable PWM signal cycle is within 0.9ms~1100ms.
・When P087=1, setting value of "P039: SW4 function select" and "P040: SW5 function select"
are invalid.
