4.3 Commissioning with control signal terminals (default settings)
The start enable is done by actuating one of the digital inputs with +24 V:
• Terminal 2: FWD = Clockwise rotating field (Forward Run)
• Terminal 3: REV = Counterclockwise rotating field (Reverse Run)
The FWD and REV control commands are interlocked (exclusive OR) and
require a rising voltage edge.
The frequency is shown with a minus sign with a start release for a left
rotating field (REV).
▶ You can now set the output frequency (0 - 50 Hz) and, as a result, the
speed of the connected three-phase motor (0 - n
potentiometer via terminal 6 (0 - +10 V proportional voltage signal). The
output frequency will then be changed after a delay according to the
specified acceleration and deceleration times. In the default settings,
these times are set to 5 seconds each, from frame size FS4, they are set
to 10 seconds each.
The acceleration and deceleration ramps specify the time change for the
output frequency: from 0 to f
to 0.
If the release signal (FWD, REV) is switched off during operation, the inverter
is blocked immediately (STOP) and the output frequency is set to 0.
The motor runs down unguided (see ① in figure 94).
The acceleration time is set in parameter P1-03.
