Stall Prevention During Regeneration
Program Protection Stall
The function of this parameter is to disable the Over-Voltage Stall (F305) and
the Over-Current Stall (F017) function during regeneration only.
Application-specific conditions may occur that warrant disabling the Stall
function during regeneration.
Settings:
0 — Disabled (Stall During Regenerative Braking)
1 — Enabled (No Stall During Regenerative Braking)
Direct Access Number — F453
Parameter Type — Selection List
Factory Default — Enabled
Changeable During Run — Yes
Time-Based Alternation Direct Mode Emergency Setpoint
Program Virtual Linear Pump Time-Based Alternation
During Time-Based Alternation operation, while running in the Direct mode,
this parameter sets the Virtual Linear Pump setpoint.
Direct Access Number — F456
Parameter Type — Numerical
Factory Default — 10
Changeable During Run — Yes
Minimum — F394 Setting
Maximum — F395 Setting
Units — %
Current Control Proportional Gain
Program Feedback PG Settings
This parameter sets the sensitivity of the ASD when monitoring the output
current to control speed.
The larger the value entered here, the more sensitive the ASD is to changes in
the received feedback.
Direct Access Number — F458
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 0.0
Maximum — 100.0
Speed Loop Proportional Gain
Program Feedback PG Settings
During closed-loop operation, this parameter sets the response sensitivity of the
ASD 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 — 12
Changeable During Run — No
Minimum — 1
Maximum — 9999
Speed Loop Stabilization Coefficient
Program Feedback PG Settings
During closed-loop operation, this parameter sets the response sensitivity of the
ASD 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
Program Feedback PG Settings
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
