Start-Up In V V W Mode - WEG CFW100 Programming Manual

P407 – Motor Rated Power Factor
Adjustable 0.50 to 0.99
Range:
Properties: cfg, V V W
Description:
The setting of parameters P401, P402, P403, P404 and P407 must be according to the data on the nameplate
of the motor used, taking into account the motor voltage.
P409 – Self-Tuning
Adjustable
0.01 to 99.99 Ω
Range:
Properties:
cfg, V V W
Description:
Motor phase stator resistance in ohms (Ω), assuming a star (Y) motor connection.
If the value adjusted in P409 is too high or too low for the inverter used, the inverter indicates fault F033. In
order to exit this condition, just perform a reset by using the I/O key. In this case, P409 will be loaded with the
factory default value.

10.2 START-UP IN V V W MODE

NOTE!
Read chapter 3 Installation and Connection of the user's manual before installing, powering up or
operating the inverter.
Sequence for installation, verification, power up and start-up:
1. Install the inverter: according to chapter 3 Installation and Connection of the user's manual, making all the
power and control connections.
2. Prepare and power up the inverter: according to section 3.2 Electrical Installation of the user's manual.
3. Load the correct factory default in P204: based on the motor rated frequency (set P204 = 5 for 60 Hz
motors and P204 = 6 for 50 Hz motors).
4. Adjustment of parameters and specific functions for the application: program the digital and analog
inputs and outputs, HMI keys, etc., according to the application requirements.
5. Activation of the VVW control: set P202 = 5 and parameters P399, P400, P401, P402, P403, P404 and
P407 according to the motor nameplate. Also set the value of P409. If some of those data are not available,
enter the approximate value by calculation or by similarity with WEG standard motor – see
10-3.
