Regenerative Braking Torque Limit Setting
No Path — Direct Access Only
This parameter provides a value to be used as the Regeneration Torque
Limit 1 if
F443 (Setting) is selected at parameter F442 .
Set this parameter to 250% to disable this function.
Direct Access Number — F443
Parameter Type — Numerical
Factory Default — 250.0 (Disabled)
Changeable During Run — Yes
Minimum — 0.00
Maximum — 250.0
Units — %
Speed Loop Proportional Gain
No Path — Direct Access Only
During closed-loop operation, this parameter sets the response sensitivity of the
drive when monitoring the output speed for control.
The larger the value entered here, the larger the change in the output speed for a
given received feedback signal.
Direct Access Number — F460
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 1
Maximum — 9999
Speed Loop Stabilization Coefficient
No Path — Direct Access Only
During closed-loop operation, this parameter sets the response sensitivity of the
drive when monitoring the output speed for control.
The larger the value entered here, the quicker the response to changes in the
received feedback.
Direct Access Number — F461
Parameter Type — Numerical
Factory Default — 100
Changeable During Run — Yes
Minimum — 1
Maximum — 9999
Load Moment of Inertia 1
No Path — Direct Access Only
This parameter is used for calculating accel/decel torque when compensating for
load inertia while operating in the Drooping Control mode.
Direct Access Number — F462
Parameter Type — Numerical
Factory Default — 35
Changeable During Run — Yes
Minimum — 0
Maximum — 100
V/I Input Bias
No Path — Direct Access Only
This parameter is used to fine-tune the bias of the V/I input terminals.
Note: See note on pg. 40 for more information on the V/I 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 adjusting this setting
to provide an output of zero from the ASD.
Direct Access Number — F470
Parameter Type — Numerical
Factory Default — 128
Changeable During Run — Yes
Minimum — 0
Maximum — 255
