Factory Default — Disabled

 

 

 

 

 

 

This parameter Enables/Disables the use of DC Injection braking during a

Changeable During Run — Yes

change in the direction of the motor.

 

 

 

 

 

 

 

 

 

 

Deceleration Time #1

 

 

 

 

Program Fundamental Parameters

Fundamental #1

Parameter Type — Numerical

Deceleration Time #1

 

 

 

Factory Default — (ASD-dependent)

 

 

 

 

 

 

This parameter specifies the time in seconds for the ASD output to go from the

Changeable During Run — Yes

Maximum Frequency to 0.0 Hz for the #1 Deceleration profile. The accel/

 

decel pattern may be set using Accel/Decel #1 Pattern.

Minimum — 0.1

Note: A deceleration time shorter than the load will allow may

Maximum — 6000

cause nuisance tripping and mechanical stress to loads.

Units — Seconds

Fundamental Parameters

Fundamental #2

Parameter Type — Numerical

Deceleration Time #2

 

 

 

Factory Default — (ASD-dependent)

This parameter specifies the time inseconds for the ASD output to go from the

Changeable During Run — Yes

Maximum Frequency to 0.0 Hz for the #2 Deceleration profile. The accel/

 

decel pattern may be set using Accel/Decel #2 Pattern.

Minimum — 0.1

This setting is also used to determine the deceleration rate of the Motorized

Maximum — 6000

Pot function.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Units — Seconds

Note: A deceleration time shorter than the load will allow may

 

cause nuisance tripping and mechanical⇒⇒stress to loads.

Diff Gain

Parameter Type — Numerical

This parameter determines the degree that the differential function affects the
