DC Injection on at Direction Change
Program ⇒ Protection Settings ⇒ DC Injection On Direction Change
Enable
This parameter Enables/Disables the use of DC Injection braking during a
change in the direction of the motor.
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — Yes
Deceleration Time #1
Program ⇒ Fundamental Parameters ⇒ Fundamental #1 ⇒
Deceleration Time #1
This parameter specifies the time in seconds for the ASD output to go from the
Maximum Frequency to 0.0 Hz for the #1 Deceleration profile. The accel/
decel pattern may be set using Accel/Decel #1 Pattern.
Note: A deceleration time shorter than the load will allow may
cause nuisance tripping and mechanical stress to loads.
Parameter Type — Numerical
Factory Default — (ASD-dependent)
Changeable During Run — Yes
Minimum — 0.1
Maximum — 6000
Units — Seconds
Decel Time #2
Program
⇒
Fundamental Parameters
⇒
Fundamental #2
⇒
Deceleration Time #2
This parameter specifies the time in seconds for the ASD output to go from the
Maximum Frequency to 0.0 Hz for the #2 Deceleration profile. The accel/
decel pattern may be set using Accel/Decel #2 Pattern.
This setting is also used to determine the deceleration rate of the Motorized
Pot function.
Note: A deceleration time shorter than the load will allow may
cause nuisance tripping and mechanical stress to loads.
Parameter Type — Numerical
Factory Default — (ASD-dependent)
Changeable During Run — Yes
Minimum — 0.1
Maximum — 6000
Units — Seconds
Delay Filter
Program
⇒
Feedback Settings
⇒
Delay Filter
This parameter determines the delay in the ASD output response to the motor-
control feedback signal.
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
Differential (D) Gain
Program ⇒ Feedback Settings ⇒ Diff Gain
This parameter determines the degree that the differential function affects the
output signal. The larger the value entered here, the more pronounced the
Differential Gain.
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 2.55
