Three-wire control (STA – STP – F/R)
With digital inputs configured as STA, STP and F/R, you can
operate the DV6 frequency inverter with three switches:
• STA: Start
• STP: Stop
• F/R: Reverse direction
X Program three of digital inputs 1 to 8 as STA, STP and F/R, by
entering the following values under the corresponding PNU
(C001 to C008):
– STA: 20
– STP: 21
– F/R: 22
The DV6 frequency inverter accelerates to the setpoint frequency
entered under PNU A020.
X Under PNU A001, enter the value 02 (setpoint definition
through PNU A020).
X Under PNU A002, enter the value 01 (start signal through
digital inputs).
X Under PNU A020, enter the setpoint frequency.
If you want to start the inverter through the STA input, the STP
input must be activated (inverse function, fail-safe). The signal
must be applied for only a short time (pulse). If the STP input is
deactivated, the motor is stopped. If the F/R input (pulse) is acti-
vated, the motor direction is reversed.

2 as STP (Pulse stop) and digital input 3 as F/R (reverse
direction).
