sources.
High voltage presents inside the VFD during running. Do not carry out any
operation on the VFD during running except for keypad setup. For products at
voltage levels of 5 or 6, the control terminals form extra-low voltage circuits.
Therefore, you need to prevent the control terminals from connecting to
accessible terminals of other devices.
The VFD may start up by itself when P01.21 (restart after power down) is set to
1. Do not get close to the VFD and motor.
The VFD cannot be used as "Emergency-stop device".
The VFD cannot act as an emergency brake for the motor; it is a must to install
mechanical brake device.
During driving permanent magnet synchronous motor, besides
above-mentioned items, the following work must be done before installation
and maintenance.
•Disconnect all the input power sources including main power and control

condensation occurred, if condensation does exist, take additional protective measures.
5. Check whether there is direct sunlight or animal intrusion in the application site, if yes, take
additional protective measures.
6. Check whether there is dust, explosive or combustible gases in the application site, if yes,
take additional protective measures.
Note: For a cabinet-installed VFD, its ambient temperature is the air temperature inside the cabinet.
2.5 Installation confirmation
After the VFD is installed properly, check the installation condition of the VFD.
1. Check whether the input power cable and current-carrying capacity of the motor cable fulfill
actual load requirements.
2. Check whether peripheral accessories (including input reactors, input filters, output
reactors, output filters, DC reactors, braking units and braking resistors) of the VFD are of
correct type and installed properly; check whether the installation cables fulfill requirements
on current-carrying capacity.
3. Check whether the VFD is installed on fire-retardant materials; check whether the hot parts
(reactors, braking resistors, etc.) are kept away from combustible materials.
4. Check whether all control cables are routed separately from power cables based on EMC
requirements.
5. Check whether all grounding systems are properly grounded according to requirements.
6. Check whether VFD installation clearances meet the requirements in the operation manual.
7. Check whether the VFD installation mode complies with the requirements in the operation
manual. Vertical installation should be adopted whenever possible.
8. Check whether VFD external connection terminals are securely wired with proper moment.
9. Check whether there are redundant screws, cables or other conductive objects inside the
VFD. If yes, take them out.
2.6 Basic commissioning
Carry out basic commissioning according to the following procedures before operating on the VFD.
1. Select motor type, set motor parameters and select VFD control mode according to actual
motor parameters.
2. Check whether autotuning is needed? If possible, disconnect the motor load to perform
dynamic parameter autotuning. If the load cannot be disconnected, perform static
autotuning.
3. Adjust the acceleration and deceleration time based on actual load working conditions.
4. Perform device commissioning by means of jogging. Check whether the motor runs in the
direction required. If no, it is recommended to change the motor running direction by
exchanging the motor wiring of any two phases.
5. Set all the control parameters, and carry out actual operation.

3 Product overview
3.1 What this chapter contains
This chapter mainly introduces the operation principles, product features, layouts, nameplates and
model instructions.
3.2 Basic principle
The VFD is used to control asynchronous AC induction motor and permanent-magnet synchronous
motor. The figure below shows the main circuit diagram of the VFD. The rectifier converts 3PH AC
voltage into DC voltage, and the capacitor bank of intermediate circuit stabilizes the DC voltage. The
inverter converts DC voltage into the AC voltage used byAC motor. When the circuit voltage exceeds
the maximum limit value, external braking resistor will be connected to intermediate DC circuit to
consume the feedback energy.
