1.6 Selection criteria
Select a RAMO5 or RASP5
③
device according to the supply voltage U
LN
of
the supply system
①
and the rated current of the assigned motor
②
.
The circuit type (
Δ
/
) of the motor must be selected for the supply voltage
①
.
The RASP5 unit’s rated output current I
e
must be greater than or equal to the
rated motor current. For RAMO5, current monitoring must be set to the
rated motor current.

Selection criteria
When selecting the drive, the following criteria must be known:
•
Type of motor (three-phase asynchronous motor)
•
Mains voltage = rated operating voltage of the motor (e.g. 3 AC ~ 400 V),
•
Rated motor current (recommended value, dependent on the circuit type
and the supply power supply)
•
Load Torque,
•
Starting torque,
•
Ambient temperature.
ATTENTION
Do not disconnect or connect power connectors (mains, motor)
while RAMO5 and RASP5 are operational.
