4–6 Start–Up and Operation MN735
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.

MODE
RAMP : The motor speed is reduced to zero at
a rate set by DECEL TIME (
P
5). A 2 second
pulse is applied at end of ramp
COAST : The motor is allowed to freewheel to a
standstill
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.
