Section 5: Configuration of the frequency converter
An example of control from the terminal block using the factory settings
After activating the "control place B"
(par. 2.01 = "7" - On)
, the converter is
ready for operation with terminal block control, using the following factory
settings:
•
parameter 2. 03="1"
; - speed referencing-unit: potentiometer
connected to voltage input AI1,
•
parameter 2. 05="0"
- Start/Stop: digital input DI1 (when par. 2.
08=0),
•
parameter 2. 07="0"
- direction control: digital input DI2, (when par.
2. 08=0),
•
parameter 2. 08="0"
- remote start configuration: according to the
Table 5.1.
Ap24V (16) voltage to the DI1 (10) digital input will cause the system
to start. If the voltage is removed from the DI1 (10) digital input, the system
will stop. The state of the digital input DI2 (11) determines the change of the
electric motor rotation direction. The speed is set using a potentiometer
connected between the analog input AI0 (6), voltage 10V (8) and
AGND ground (5).
Use a potentiometer with the resistance of1k..10k
,
5 k
.
recommended.
Figure 5.2 shows an example of the connection layout for controlling the
frequency converter from the terminal block. The speed referencing-unit is a
potentiometer P connected to the analog input AI1. Start / stop is done with
the switch S1 and change of direction with the switch S2.
