Open loop vector control mode (P0207.F=0 factory default)
☆
The open-loop vector control mode is applicable to FT50 series frequency converter. It is used
in scenarios where the motor is without the encoder speed feedback. In this control mode, it
requires self-learning of motor parameters to complete motor parameter identification.
DANGER
Pay attention to the risk of electric shock.
It is strictly forbidden to do the
wiring when the power is on. Even if the power supply has been cut off,
there is still dangerous voltage on the capacitor of the frequency converter.
Therefore, the device should not be opened until 10 minutes after the
power has been switched off.
WARNING
No matter where the fault occurs in the control equipment, it may cause major
equipment damage or even serious personal injury (that is, there is a
potentially dangerous fault). Therefore, additional external precautions must be
taken or additional devices used to ensure safe operation must be installed,
even in the event of a fault (for example, installation of independent current
limit switch, mechanical interlock, etc.).
Do not disassemble the shell or touch the internal circuit after the frequency
converter is electrified, otherwise there will be a risk of electric shock.
When installing the frequency converter in a closed cabinet or enclosure,
please use a cooling fan or a cooling air conditioner for cooling.
Please confirm that the input voltage of the product is within the rated voltage
range of the nameplate.
Do not place flammable and explosive materials near the frequency converter.
Prevent children and the unauthorized person from touching or approaching
the frequency converter.
This equipment can only be used for the purpose specified by the
manufacturer. Unauthorized modification or use of parts and accessories not
sold or recommended by the manufacturer of this equipment may cause fire,
electric shock and other injuries.
