1.6 Selection criteria
Select RAMO5 or RASP5 ③ according to supply voltage U
LN
of the supply
system ① and the rated operational current of the assigned motor ② .
The circuit type ( Δ /  ) of the motor must be selected according to the
supply voltage ① . The RASP’s rated output current I
e
from the RASP5 must
be greater than or equal to the rated motor current. For RAMO5, current
monitoring must be set to the rated motor current.
Figure 7: Selection criteria
When selecting the drive, the following criteria must be known:
• Type of motor (three-phase asynchronous motor)
• Grid voltage = rated voltage of the motor (e. g. 3~ 400 V),
• Rated motor current (recommended value, dependent on the circuit type
and the supply power supply)
• Load Torque,
• Starting torque,
• Ambient temperature range.
ATTENTION
Do not connect or disconnect power connectors (mains, motor)
while RAMO5 and RASP5 are operational.
