9.2 START-UP IN V/f 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 - Electric Installation of the user’s manual of the
CFW501.
3. Load the factory default with P0204 = 5 (1800 rpm / 60 Hz) or P0204 = 6 (1500 rpm /50 Hz), according to the
input rated frequency (power supply) of the inverter used.
4. In order to set a V/f curve different from the default, set the V/f curve using parameters P0136 to P0147.
5. Setting of specific parameters and functions for the application: program the digital and analog inputs and
outputs, HMI keys, etc., according to the application requirements.
For applications:
„
Simple applications that can use the factory default programming of the analog and digital inputs and outputs,
use the HMI “BASIC” menu.
„
Applications that require just the analog and digital inputs and outputs with programming different from the
factory default, use the HMI “I/O” menu.
„
Applications that require functions such as flying start, ride-through, DC braking, rheostatic braking, etc.,
access and modify the parameter of those functions in the HMI “PARAM” menu.
