Panasonic VF200 Instruction Manual page 18

Do not use a magnetic contactor which is connected to power side or
load side of the inverter to start or stop the motor (inverter).
Frequent ON/OFF switching on the power supply side can cause inverter
malfunction. Also, do not conduct ON/OFF switching on load side during
inverter operation, or it can cause fault trip of the inverter. Start or stop the
motor by operating signals of the inverter only.
Do not connect a power capacitor or a surge absorber to output side
of the inverter.
Such device can damage the inverter, resulting in broken of capacitors and
other parts. Remove it if connected.
Do not use the inverter for load other than a motor or for a 1-phase
motor.
If parameters are frequently written in, service life of built-in
non-volatile memory (EEPROM) of the inverter will be shortened.
The maximum life of non-volatile memory (EEPROM) used in VF200 is
100,000 times. Therefore, do not write in parameters frequently.
Precautions for inverter's protection function
The inverter integrates various protection functions such as stall prevention,
current limiting and over-current shut-off. These protection functions are
functions used to protect the inverter against the sudden abnormal conditions,
instead of general control functions.
Therefore, avoid using them in applications where they will be activated under
normal conditions.
Failure to do so may reduce the inverter's service life or damage the inverter.
Always measure the output current, etc. with a meter, check the details of the
fault trip memory, and confirm that operation conditions conform to the
precautions and specifications are correct.
