Compact design
The integrated servo drives of the AMI812x series combine servo-
motor, servo drive and fieldbus connection in a space-saving design
for all motion requirements in the power range up to 400 W.
Machines without control cabinet
You can place the integrated servo drives of the AMI812x series as
EtherCAT slave directly at the machine without control cabinet and
without upstream I/O level. This allows compact machines to be re-
alized without a control cabinet.
Neodymium permanent magnets
The magnets installed in the servo drives are permanent magnets.
Neodymium is a hard magnetic material that enables the precise
and highly dynamic positioning of the servo drives.
Three-phase stator winding
The three-phase winding in the stator reduces the amount of mate-
rial required while maintaining the same electrical output. All phase
angles are 120°.
Electronic commutation in the power section
The servo drives are commutated electronically. The three coil turns
are supplied from a bridge circuit.
Thermal contacts
A thermal contact LPTC-600 is installed to monitor and measure the
winding temperature and to protect the servo drive against overheat-
ing. This can be read out by the user.
Temperature warning and switch-off:
• Warning temperature at 120 °C
• Switch-off temperature at 140 °C
