Stall Prevention During
Regeneration
This parameter Enables/Disables the Overvoltage Stall (F305) and the
Overcurrent Stall (F017) function during regeneration only
. Application-
specific conditions may occur that warrant disabling the Stall function during
regeneration.
Settings:
With Stall Prevention
Without Stall Prevention
Direct Access Number — F453
Parameter Type — Selection List
Factory Default — With Stall
Prevention.
Changeable During Run — Ye s

Current Differential Gain
This parameter determines the degree that the current differential function
affects the output signal. The larger the value entered here, the more
pronounced the Current Differential Gain.
Direct Access Number — F454
Parameter Type — Numerical
Factory Default — 1.23
Changeable During Run — Ye s

VI/II
⇒
Bias
This parameter is used to fine-tune the bias of the VI/II input terminals.
Note: See note on pg. 33 for further information on the VI/II terminal.
This setting may be used to ensure that the zero level of the input source (pot,
pressure transducer, flow meter, etc.) is also the zero level setting of the ASD
system.
This is accomplished by setting the input source to zero and either increasing or
decreasing this setting to provide an output of zero from the ASD.
Direct Access Number — F470
Parameter Type — Numerical
Factory Default — 100
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 255

Gain
This parameter is used to fine tune the gain of the VI/II input terminals.
Note: See note on pg. 33 for further information on the VI/II terminal.
This setting may be used to ensure that the 100% level of the input source (pot,
pressure transducer, flow meter, etc.) is also the 100% level setting of the ASD
system.
This is accomplished by setting the input source to 100% and either increasing
or decreasing this setting to provide an output of 100% from the ASD.
Direct Access Number — F471
Parameter Type — Numerical
Factory Default — 50
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 255
