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.
