Operation using an external potentiometer
Configuration of the parameters
Method of operation
You can start the frequency inverter in a clockwise direction with
terminal FW and in an anticlockwise direction with terminal 8. If
both terminals are closed simultaneously, a stop signal is issued.
With the externally connected potentiometer, the required
frequency setpoint (voltage setpoint) can be defined.
You can use the measuring instrument to display the frequency
(PNU C023 = 00) or the motor current (PNU C023 = 01). With
PNU b081, you can match analog output FM to the measuring
instrument’s measuring range (indication: frequency or current).
Operation through an analog setpoint value
Configuration of the parameters
Method of operation
Inputs FW and 8 function exactly as described in the previous
example.
With digital input 3 (configured as AT), you can change over from
a voltage setpoint value (0 to 10 V) to a current setpoint value
(4 to 20 mA).
Instead of a fixed or switched connection on terminal 3, you can
set PNU C013 to 01. Digital input 3 is then configured as a break
contact (NC).
The circuit example also includes a motor PTC thermistor. It is
important to use a screened control cable and to lay the motor PTC
thermistor cable separately from the other motor cables. However,
the screen should be earthed at the inverter side only.
