Table 14: LEDs
Standard operation, actuation with default settings
Connect cables as shown below.
With the default settings (a fig. 53) you can:
• start and stop the motor (S1 or S2),
• reverse the direction of rotation (S2 or S1),
• reset (RST) fault signals (ALARM),
• control the motor speed (0 to 50 Hz, or 0 to 60 Hz for
DF51-320-…) with potentiometer R1 through the analog
reference value input.
Switches and potentiometer are not included as standard with the
frequency inverter.
X Switch on the supply voltage.
The POWER LED is lit.
X Close switch S1 (FWD = clockwise rotation).
The frequency inverter generates a clockwise rotating field and the
motor, if connected normally, rotates in a clockwise direction.
X With potentiometer R1, you can change the frequency and
therefore the motor speed.
X Open switch S1.
The motor speed is reduced to zero.
X Close switch S2 (REV = anticlockwise rotation).
The frequency inverter generates an anticlockwise rotating field
and the motor, if connected normally, rotates in an anticlockwise
direction.
X With potentiometer R1, you can change the frequency and
therefore the motor speed.
X Open switch S2.
The motor speed is reduced to zero.
If both switches S1 and S2 are closed, the motor will not start. The
motor speed reduces to zero during operation if you close both
switches.
If a fault has occurred due to overcurrent or overvoltage, increase
the acceleration or deceleration time. You can change the
parameters through the built-in keypad, an optional external
keypad (DEX-KEY-6…) or the Drive Soft parameterization
software. The software is included on the CD-ROM supplied with
the frequency inverter. To reset fault signals, close RST.

Display Explanation
POWER Red LED is lit when the frequency inverter has
power.
ALARM
Red LED is lit when an alarm message is issued.
RUN Green LED lit when frequency inverter operational
(Enable signal for clockwise/anticlockwise
operation, terminal 1 or 2) or running.

The Reset signal (RST function) is also issued when you
switch the supply voltage off (POWER LED off).

Caution!
During initial operation, check the following to prevent
damage to the motor:
• Is the direction of rotation correct?
• Does a fault (ALARM LED) occur during acceleration or
deceleration?
• Is the motor speed correct?
• Does any unusual motor noise or vibration occur?
