8 Initial switch-on
Which settings are necessary for the drive to operate?
After mains connection the inverter is ready to operate after approx.
0.5 seconds.
The frequency inverters are factory-set such that a four-pole
standard motor with 400V rated voltage and 50Hz according to the
combinations in section 3.1 can be operated without further
settings.
In case of motor ratings according to section 3.2 or 3.3, page 17ff,
it is necessary to increase the permanent output power accordingly.
Using the codes C119 and C120 the output current monitoring must
be set to increased power or maximum power (see page 85). The
I
0
set-value (C020) must also be adapted to the motor (see page
70).
The motor will rotate if:
•
the controller is enabled:
Apply a voltage of 13 to 30V (HIGH signal) across terminal 28.
•
the direction of rotation is set :
CW rotation:
Apply a voltage of 13 to 30V
(HIGH signal) across terminal 21.
CCW rotation: Apply a voltage of 13 to 30V
(HIGH signal across terminal 22.
•
the set-value is not zero:
Apply a voltage higher than 0V (maximum 10V) across
terminal 8.
Reference potential for the terminals 21, 22, 28 is terminal 39.
When operating with internal voltage supply (terminal 20), bridge
terminals 39 and 40. Reference potential for the set-value input
terminal 8 is terminal 7.
If you want to operate the inverter using the LECOM program,
additional settings are required.
