B150: Carrier Mode – If B083 Carrier Frequency setting is greater than 4 kHz, then the B150 Carrier Mode function (if enabled) will reduce the actual carrier frequency downward to 4 kHz as the inverter’s internal termperature increases.

B151: Quick start enable – This function and the intelligent input [RDY] (option code

52)have the same effect. If you need the inverter output to always have a quick response, use parameter B151 and do not assign the [RDY] input. Otherwise, disable Quick Start Enable (set B151=00) and assign the [RDY] input. Then you can enable the Quick Start feature only when necessary. When the Quick Start feature is enabled, then access to parameter editing is the same as when the inverter is in Run Mode.

NOTE: Parameter B151 cannot be read and copied to another inverter. This prevents turning ON another inverter’s output unexpectedly.
