Voltage Compensation Coefficient for Dead Time
Program Special Special Parameters
This parameter adjusts the degree of voltage compensation during Dead Time
by increasing or decreasing the on-time of the programmed PWM just prior to
the start of the Dead Time.
Dead Time Compensation
Program Special Special Parameters
This parameter Enables/Disables the Dead Time Compensation function. The
Dead Time Compensation feature provides a smoothing of the on-off IGBT
signal that feeds the Gate Driver board during the off portion of the on-off
cycle.
Settings:
0 — Enabled
1 — Disabled
Dead Time Compensation Bias
Program Special Special Parameters
This parameter sets a bias for the Dead Time Compensation function. The
Dead Time Compensation feature provides a smoothing of the on-off IGBT
signal that feeds the Gate Driver board.
Switching Frequency Between Current and Voltage Control
Program Special Special Parameters
This parameter sets the threshold frequency at which ASD control is switched
between current control and voltage control.
Acceleration Time 2
Program Special Acc/Dec (1 - 4) Settings
This parameter specifies the time in seconds for the drive to go from 0.0 Hz to
the Maximum Frequency for the Acceleration (Acc) 2 Profile. The
Acceleration/Deceleration (Acc/Dec) pattern may be set using S-Curve Acc/
Dec Pattern 1 (F502). The minimum Acc/Dec time may be set using Acc/Dec
Time Lower Limit (F508).
This setting is also used to determine the acceleration rate of the UP/DOWN
Frequency function.
Note:
An acceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads.
Automatic Acceleration/Deceleration, Stall, and Ridethrough
settings may lengthen the acceleration time.
