Quick commissioning
Connection
If a 4-pole standard motor is to be controlled
by an SK 200E series frequency inverter of
the same power, it is possible to operate the
frequency inverter without any aids for test
purposes.
The only prerequisite for this is the correct
connection of the mains and motor cables to
the appropriate terminals
(PE, L1, N (/L2, L3)
and U, V, W)
of the frequency inverter
(Section 2.7), and their supply with a 24V DC
control voltage
(Connection to terminals 44/40
(Section 2.8))
Mains unit
If an SK xU4-…-24V is used to provide the
24V control voltage, this must be connected as described in Section 3.4.1 or 3.5.2 .
DIP switches
For test operation the DIP switches 1 to 5 of
the frequency inverter must be set to the
"
OFF " position (Section 5.1.2) and the digital
input DIN1 (terminal 21) must be hard-wired
to the 24V control voltage (terminal 44).
Control
Enabling is carried out as soon as the
inverter's own setpoint potentiometer
(Potentiometer P1, Section 5.1.3) is moved
from the 0% position.
The setpoint can be adjusted to the
requirements by further continuous adjustment
of the potentiometer.
Resetting the setpoint to 0% sets the
frequency inverter into "Standby" status.
Stepwise adjustment of the ramp times within
defined limits is also possible with the aid of
potentiometer P2 (Section 5.1.3)
P1 = Setpoint potentiometer
P2 = Ramp setting
