Parameter Definitions You can program the Inverter for specific applications. The Inverter is supplied with pre–programmed applications that can be used as starting points for application–specific programming. Programming is simply selecting an application, changing some of the parameter values and finally saving the changes. Each application configures the terminal wiring for a differently. The Inverter retains the new settings during power–down. The next time the inverter is powered up, the new settings will be used.

Note: Motor parameters are not changed when a new application is loaded.

INJECTION : On a stop command, the motor

 

 

volts are rapidly reduced at constant frequency to deflux the motor. A low frequency braking current is then applied until the motor speed is almost zero. This is followed by a timed DC pulse to hold the motor shaft.
