4.3 Commissioning with control signal terminals (default settings)
The frequency is shown with a minus sign with a start release with 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
change in output frequency here is delayed based on the specified accel-
eration and deceleration ramps. When using the device's default
settings, these times will be set to 5 seconds.
The acceleration and deceleration ramps specify the time change for the
output frequency: from 0 to f
Figure on Page 87 shows a good example of the process, if the release
signal (FWD/REV) is switched on and the maximum setpoint voltage (+10 V)
is applied. The speed of the motor follows the output frequency depending
on the load and moment of inertia (slip), from zero to n
If the release signal (FWD, REV) is switched off during operation, the inverter
is blocked immediately (STOP). The motor comes to an uncontrolled stop
(see ① in Figure).
The acceleration time is set in parameter P-03.
Information on settings and the description of the parameters used here is
provided in section "Drives control", Page 105.
