  • Page 34 Parameters 2.8.5—2.8.8, Motor thermal protection: General The motor thermal protection is to protect the motor from overheating. The Vacon drive is capable of supplying higher than nominal current to the motor. If the load requires this high current there is a risk that the motor will be thermally overloaded. This is the case especially at low frequencies.
