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 5. 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 C027 = 00) or, for example, the motor current
(PNU C027 = 01). With PNU b081, you can adjust analog output
FM to the corresponding measurement range of the measurement
device (frequency or current can be displayed).
Operation through an analog setpoint value
Configuration of the parameters
Method of operation
Inputs FW and 5 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 the wiring on terminal 3, which is fixed or realized using
a switch, 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.
