Accel/Decel Time Switching Frequency
Accel/Decel times can be changed automatically without using multi-function inputs. When multi-
function digital inputs are set for Accel/Decel selection, this command has priority over automatic
change of Accel/Decel.
Table 5-11: Accel/Decel Time Switching Frequency Parameter Settings
Jump Frequencies
This function allows the “jumping” of critical frequencies so that the motor can operate without
resonant vibrations caused by some machine systems. This function is also used for deadband
control. Setting the value to 0.0 Hz disables this function.
