2.6 Using restriction

If the nominal torque is hold in the stopped position or at very low speed (< 10 rpm), the torque should
be limited to 80% of Io (permanent current at low speed) to avoid an excessive overheating of the
motor. The front flange should normally dissipate a part of the losses of the motor. The size of the end-
plate should be at least 400 mm square and 12mm thickness.
The resolver cable must be separated from the power cable.
Cables fitted with connectors may be provided by us : ask for
details.
The cable is made up of 6 wires twisted and shielded in pair.
The shielding must be earthed on the servoamplifier side only
The recommended cable can use resolver signals from up to 50 m
away. For greater distances ask for details.
Servoamplifier connection: comply with the relevant servoamplifier
installation instructions.
