Goodrive20-UL Series VFD
Optional peripheral accessories
-151-
inertial energy of the motor and load return to the VFD to charge the capacitors in the main DC
circuit. When the voltage increases to the limit, damage may occur to the VFD. It is necessary
to apply braking unit/resistor to avoid this accident happens.
Only qualified electricians are allowed to design, install, commission and
operate on the VFD.
Follow the instructions in "warning" during working. Physical injury or
death or serious property may occur.
Only qualified electricians are allowed to wire. Damage to the VFD or
braking options and part may occur. Read carefully the instructions of
braking resistors or units before connecting them with the VFD.
Do not connect the braking resistor with other terminals except for PB and
(-). Do not connect the braking unit with other terminals except for (+) and
(-). Damage to the VFD or braking circuit or fire may occur.
Connect the braking resistor or braking unit with the VFD according to the
diagram. Incorrect wiring may cause damage to the VFD or other devices.
Goodrive20-UL series VFDs have internal braking units.
