Voltage Compensation Coefficient for Dead Time
Program
Special Control
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.
Direct Access Number — F488
Parameter Type —
Numerical
Factory Default —
163.8
Changeable During Run —
Yes
Minimum — 1.64
Maximum — 327.6
Dead Time Compensation (Enable)
Program
Special Control
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
Direct Access Number — F489
Parameter Type —
Selection List
Factory Default —
Enabled
Changeable During Run —
Yes
Dead-time Compensation Bias
Program
Special Control
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.
Direct Access Number — F490
Parameter Type —
Numerical
Factory Default —
0.000
Changeable During Run —
Yes
Minimum — -32.768
Maximum — 32.767
Switching Frequency of Current/Voltage Control
Program
Special Control
Special Parameters
This parameter sets the threshold frequency at which ASD control is switched
between Current-control and Voltage -control.
Direct Access Number — F491
Parameter Type —
Numerical
Factory Default —
40.00
Changeable During Run —
Yes
Minimum — 10.00
Maximum — 60.00
Units — Hz
Accel #2 Time
Program
Special Control
Accel/Decel #1-#4
This parameter specifies the time in seconds for the drive to go from 0.0 Hz to
the
Maximum Frequency
for the
#2 Acceleration
profile. The accel/decel
pattern may be set using
. The minimum accel/decel time may be set using
This setting is also used to determine the acceleration rate of the
Motorized Pot
function.
Note:
An acceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads.
Automatic Accel/Decel
and
Stall
settings
may lengthen the
acceleration time.
Direct Access Number — F500
Parameter Type —
Numerical
Factory Default — (ASD dependent)
Changeable During Run —
Yes
Minimum — 0.1
Maximum — 6000
Units — Seconds
