Commissioning And Running - INVT Goodrive 310-UL Series Operation Manual

GD310-UL series VFD
 Install away from children and other public places.
 Please use the VFD on appropriate condition (See chapter Installation environment).
 Don't allow screws, cables and other conductive items to fall inside the VFD.
 The leakage current of the VFD may be above 3.5mA during operation. Proper and reliable
grounding is essential before connecting to power supply. Ground with proper techniques and
ensure the grounding resistor is less than 10Ω. The conductivity of PE grounding conductor is the
same as that of the phase conductor (with the same cross sectional area).
 R, S and T are the input terminals of the power supply, while U, V and W are the motor terminals.
Please connect the input power cables and motor cables with proper techniques; otherwise the
damage to the VFD may occur.

because of the external load. It is recommended to install effectively external
braking devices or disconnect the electric wiring between the motor and the VFD
directly.
Note:
 Do not switch on or off the input power supply of the VFD frequently.
Disconnect all power supplies applied to the VFD before the terminal wiring
and wait for at least the designated time after disconnecting the power supply.
High voltage is present inside the VFD during running. Do not carry out any
operation except for the keypad setting.
The VFD may start up by itself when P01.21=1. Do not get close to the VFD
and motor.
The VFD cannot be used as "Emergency-stop device".
The VFD cannot be used to break the motor suddenly. A mechanical braking
device should be provided.
Besides the above items, check to ensure the following ones before the
installation and maintenance during the running of the permanent
synchronous motor:
All input power supply is disconnected (including the main power supply and
The permanent magnet synchronous motor has stopped running and
The waiting time of the permanent magnet synchronous motor after stopping
Ensure the permanent magnet synchronous motor does not rotate again
