Basic Functions; Extended Functions Of Groupa - Watt Drive L2000 Series Manual

Explanation of display after power on:
When the inverter is turned on, the display returns to what was displayed when the power was last
turned off (except in the extended function mode).

Extended functions of group A
Group A comprises a variety of functions, among them functions for adjusting the frequency set value,
functions for setting up multistage speed settings, as well as functions for configuring parameters for a DC
brake, etc.

Function description / parameter setting range
Setting range 0.5Hz–360Hz (resolution +/-0.1Hz).
The frequency can be set using the following methods:
Using F 01 and A 20: Enter the parameter 02 under A 01.
Using the potentiometer on the digital operator. Enter the
parameter 00 under A 01.
By means of a voltage of 0–10 V or a current of 4–20mA at
input terminals O or OI. Enter the parameter 01 under A 01.
Y
Using the digital input terminals configured as CF1–CF4. After
selecting the desired frequency stage by applying logic levels
to the digital inputs, the frequency for the selected stage can
be entered. (Note: Multistage speed settings can also be
entered using A21-A35).
The frequency set value display is independent of the method
with which the set value was entered.
Setting range 0.1s–3000s. (Resolution 0.1s in the range of 0.1
Y
through 999.9. Resolution 1s in the range of 1000 through 3000).
Setting range 0.1s–3000s. (Resolution 0.1s in the range of 0.1
Y
through 999.9. Resolution 1s in the range of 1000 through 3000).
After pressing the RUN key the motor starts in forward running
N
mode (parameter 00) or in reverse running mode (parameter 01).
Function description / parameter setting range
Main functions
There are three different ways to set the output frequency:
00: using the potentiometer on the digital operator
N
01: using analog input terminals O (0-10V) or OI (4-20mA)
02: using functions F 01 or A 20
The command for starting the motor can be issued via:
01: the digital inputs configured as FW or RV
N
02: the RUN key on the digital operator
The base frequency is the frequency where the output voltage
N
has its maximum value. Setting range 50Hz–360Hz.
