Startup
Required data
The following data is required to ensure startup is successful:
• Motor type (SEW or non-SEW motor)
• Motor data
– Nominal voltage and nominal frequency
– Additionally for non-SEW motors: Nominal current, nominal power, power factor
cos
φ
, and nominal speed.
• Nominal line voltage
Activating startup
Prerequisites:
• Drive ”no enable”:
Stop
If a smaller or a larger motor is connected (maximum difference one size), then you have
to choose the value closest to the rated motor power.
The startup procedure is not complete until you have returned to the main menu level
by pressing the OUT key.
Multi-motor drive
startup
Multi-motor drives are mechanically coupled to each other (e.g. chain drive with multiple
motors).
Observe the notes in the "MOVIDRIVE
®
Multi-Motor Drives" manual.
Group drive startup
Group drives are mechanically decoupled from each other (e.g. different conveyor
belts). In this operating mode, the inverter operates without slip compensation and with
a constant V/f ratio.
Observe the notes in the "MOVIDRIVE
®
Multi-Motor Drives" manual.
Startup with large
load mass moment
of inertia, such as
with pumps and
fans
The slip compensation is designed for a load mass moment of inertia to motor moment
of inertia ratio smaller than 10. If the ratio is larger and the drive vibrates, then slip com-
pensation must be reduced and even be set to 0 if necessary.
Manual operation
with FBG11B set-
point adjuster
FBG11B setpoint adjuster of the keypad
(local manual mode): LED
flashes.
The only relevant parameters in "FBG setpoint adjuster" operating mode are:
•
P122 Direction of rotation FBG manual operation
• RUN key and STOP/RESET key
• Setpoint adjuster (potentiometer)
When the FBG setpoint adjuster is activated, the symbol flashes.
You limit the smallest speed with
P301 Minimum speed
and the largest speed with the
n
max
symbol.
After an error, a reset can be performed using the STOP/RESET button via the terminal
or the interface. After a reset, the "manual setpoint adjuster" operating mode will be ac-
tive again. The drive remains stopped.
INFORMATION
The SEW motor startup is designed for 4-pole motors. It may be useful to start up 2-
pole or 6-pole SEW motors as non-SEW motors.
