G7 ASD Operation Manual 143
Accel/Decel Lower Limit Time
Program ⇒ Special Control Parameters ⇒ Accel/Decel Special
This parameter sets the lower limit of the Accel/Decel time.
Direct Access Number — F508
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Ye s
Minimum — 0.01
Maximum — 10.00
Units — Seconds
Accel #3 Time
Program ⇒ Special Control Parameters ⇒ Accel/Decel #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 #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 and Stall settings may lengthen the
acceleration time.
Direct Access Number — F510
Parameter Type — Numerical
Factory Default — (ASD-dependent)
Changeable During Run — Ye s
Minimum — 0.1
Maximum — 6000
Units — Seconds
Decel #3 Time
Program ⇒ Special Control Parameters ⇒ Accel/Decel #1 – #4
Settings
This parameter specifies the time in seconds for the drive 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 and Stall settings may lengthen the
deceleration time.
Direct Access Number — F511
Parameter Type — Numerical
Factory Default — (ASD-dependent)
Changeable During Run — Ye s
Minimum — 0.1
Maximum — 6000
Units — Seconds
Accel/Decel Pattern #3
Program ⇒ Special Control Parameters ⇒ Accel/Decel #1 – #4
Settings
This parameter enables a user-selected preprogrammed output profile that
controls the acceleration and deceleration pattern for the #3 Accel/Decel
parameter.
Settings:
Linear
S-Pattern 1
S-Pattern 2
Direct Access Number — F512
Parameter Type — Selection List
Factory Default — Linear
Changeable During Run — Ye s
Accel/Decel Switching Frequency #2
Program ⇒ Special Control Parameters ⇒ Accel/Decel Special
This parameter sets the frequency at which the acceleration control is switched
from the Accel #2 profile to the Accel #3 profile during a multiple-acceleration
profile configuration.
Direct Access Number — F513
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Ye s
Minimum — 0.00
Maximum — Max. Freq. (F011)
Units — Hz
