VFD500 high performance vector control frequency inverter user manual
packing water, parts missing or damaged parts, please do not install!
➢
Packaging logo and physical name does not match, please do not
➢
install!
Handling should be light lift, otherwise there is the danger of damage
➢
to equipment!
Do not use damaged drive or missing drive. Risk of injury!
➢
Do not touch the control system components by hand, or there is the
➢
danger of electrostatic damage!
Please install the flame retardant objects such as metal, away from
➢
combustibles, or may cause a fire!
Do not allow lead wires or screws to fall into the drive, otherwise the
➢
drive may be damaged!
Install the drive in a place where there is less vibration and direct
➢
sunlight.
Drive placed in airtight cabinet or confined space, please note the
➢
installation of space to ensure the cooling effect.
You must follow the guidance of this manual and be used by
➢
qualified electrical engineers. Otherwise, unexpected danger may
occur!
There must be a circuit breaker between the drive and the power
➢
supply, otherwise a fire may occur!
Make sure the power supply is in zero-energy state before wiring,
➢
otherwise there is danger of electric shock!
Please follow the standard to the drive properly grounded, otherwise
➢
there is the risk of electric shock!
Never connect input power to the drive's output terminals (U, V, W).
➢
Note that the terminal markings, do not take the wrong line!
Otherwise it will cause damage to the drive!
Never connect the braking resistor directly to the DC bus +, -
➢
terminals. Otherwise it will cause a fire!
Refer to the manual's recommendations for the wire diameter used.
➢

Otherwise, the internal of the servo driver may be damaged.
Make sure the voltage level of the input power is the same as the
➢
rated voltage of the driver. Check if the wiring position of the power
input terminals (R, S, T) and output terminals (U, V, W) is correct; Of
the external circuit is short-circuited, the connection is tightened, or
cause damage to the drive!
No part of the drive need to withstand voltage test, the product has
➢
been made before the test. Otherwise it may cause accident!
