166 GX9 ASD Installation and Operation Manual
S-Pattern Acceleration Lower-Limit Adjustment
Program Special Accel/Decel Special
During an S-Pattern 1 or 2 sequence, this parameter settings modifies the
acceleration rate for the lower part of the acceleration curve by the percentage
set here.
This function is commonly used with transportation and lifting applications.
See parameter F502 for more information on this setting.
Direct Access Number — F506
Parameter Type — Numerical
Factory Default — 25
Changeable During Run — Yes
Minimum — 0
Maximum — 50
Units — %
S-Pattern Acceleration Upper-Limit Adjustment
Program Special Accel/Decel Special
During an S-Pattern 1 or 2 sequence, this parameter settings modifies the
acceleration rate for the upper part of the acceleration curve by the percentage
set here.
This function is commonly used with transportation and lifting applications.
See parameter F502 for more information on this setting.
Direct Access Number — F507
Parameter Type — Numerical
Factory Default — 25
Changeable During Run — Yes
Minimum — 0
Maximum — 50
Units — %
Acceleration/Deceleration Time Lower Limit
Program Special Accel/Decel Special
This parameter sets the lower limit of the Accel/Decel time settings.
Direct Access Number — F508
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 10.00
Units — Seconds
Acceleration Time 3
Program Special Accel/Decel (1 – 4) Settings
This parameter specifies the time in seconds for the output of the ASD to go
from 0.0 Hz to the Maximum Frequency for the 3 Acceleration profile. The
Accel/Decel pattern may be set using F502. The minimum Accel/Decel time
may be set using F508.
Note: An acceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads. Automatic
Accel/Decel, Stall, and Ridethrough settings may lengthen the
acceleration times.
Direct Access Number — F510
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — Acc/Dec Lower Limit
(F508)
Maximum — 6000.00
Units — Seconds
Deceleration Time 3
Program Special Accel/Decel (1 – 4) Settings
This parameter specifies the time in seconds for the output of the ASD to go
from the Maximum Frequency to 0.0 Hz for the 3 Deceleration profile.
The Accel/Decel pattern may be set using F502. The minimum Accel/Decel
time may be set using F508.
Note: A deceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads. Automatic
Accel/Decel, Stall, and Ridethrough settings may lengthen the
deceleration times.
Direct Access Number — F511
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — Acc/Dec Lower Limit
(F508)
Maximum — 6000.00
