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.
Figure 7: 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.
