Parameterization of motor protection (P340)

When this function is activated, MOVITRAC^® B takes over the thermal protection of the connected motor by electronic means. In most cases, the motor protection function is comparable to standard thermal protection (motor protection switch) and, furthermore, it takes account of speed-dependent cooling by the integrated fan. Motor utilization is determined using the inverter output current, cooling type, motor speed and time. The thermal motor model is based on the motor data entered during startup (MOVITOOLS^® MotionStudio/DBG60B) and when the operating conditions specified for the motor are observed.
