Supply voltage (POWER)
The DF51 frequency inverters can be supplied with AC voltage
(50/60 Hz mains voltage) or DC voltage. In both cases the energy
is loaded into the internal DC link where it is stored in capacitors.
The internal DC link, in turn, supplies the switched-mode power
supply, generating the required control voltage for the electronics,
the reference voltage (+10 V) and the voltage for the control
signal terminals (+24 V). Charging of the internal DC link and
correct operation of the switched-mode power supply is indicated
by the red POWER LED.
With PNU b001 to b005 you can define the frequency inverter’s
behaviour when an undervoltage signal (E 09) is detected.

– j 00 Fault signal E 09, automatic restart at 0 Hz. Fault signal E 09. When you
acknowledge the fault signal (RST or Stop key on the keypad), the drive
automatically starts up again with 0 Hz.
00
01 Automatic restart at set starting frequency after expiry of time set with
PNU b003.
02 After the time set with PNU b003 has elapsed, the frequency inverter
synchronizes to the current motor rotation speed and the motor is
accelerated to the current reference value in the set ramp times.
03 After the time set under PNU b003 has elapsed, the inverter
synchronizes to the current motor rotation speed and the motor brakes
to a stop in the set deceleration time. A fault message is then displayed..

– j 0.3 – 25 s Here, you set a time duration during which the undervoltage condition
is met without the corresponding fault message in PNU E 09 being
initiated.

– j 0.3 – 100 s Here, set a time which is to expire before an automatic restart is
initiated after a fault signal. This time can also be used in conjunction
with the FRS function. During the delay, the following message appears
on the LED display:
