 PUTTING IN OPERATON THE FREQUENCY CONVERTER FOR THE FIRST TIME
8
CAUTION
Prior to put in operation the frequency converter read through thoroughly the description below!
Follow all safety measures, warnings and instructions described in this manual!
Heed the safety messages in this manual.
The operating company is responsible for any injuries or equipment damage resulting from failure to heed the
warnings in this manual.
▪ Check up the operational data of the frequency converter to be put in operation.
 page 4. - General features
▪ Install the device according to the instructions.
 page 5. - Mechanical installation
▪ Study the safety measures to be complied with.
 page 6. - Test run
▪ Connect the cables of the power line, the motor and the control elements to the corresponding terminal
blocks.
 page 10. - Assignment and connection of the V3D terminal block
 page 13. - Assignment and connection of the VLD / VHD terminal block
▪ If the device is equipped with brake check up the value and the placing of the brake resistor.
 page 20. - Selection guide for brake resistors
▪ Switch the line power to the device.
▪ At devices without programming unit the motor can be started with the device’s control elements according
to the default setting (or the required setting).
▪ At devices with programming unit check up and if necessary modify the preset parameters (rising times and
fall times, minimum and maximum frequency etc.)
▪ If possible, perform a trial start with unloaded motor:
• inspect the operation of the motor,
• in case of opposite direction of rotation interchange both phase wires of the motor to achieve the right
basic direction of rotation,
i
Interchanging the phase wires at the mains side does not influence the direction of
rotation!
• with changing the reference signal (e.g. potentiometer) scan the operating frequency band,
• try the functioning of the other controls (e.g. change of direction of rotation)
▪ Let the motor run with load!
▪ If necessary modify the parameters (rising times and fall times, minimum and maximum frequency etc.)
▪ In regulating mode tune the PID parameters
▪ If the settings are appropriate save the parameters!
