Torque Limit Mode (Speed Dependent)
Program
Torque Setting
Torque Limit Settings
This parameter allows for either wide or very limited speed fluctuations while
operating in the
Torque Control
mode.
The ASD output follows the commanded speed when
No Speed Cooperation
is selected and has a very limited speed fluctuation range when
Standard
is
selected.
Settings:
0 — Standard
1 — No Speed Cooperation
Direct Access Number — F451
Parameter Type —
Selection List
Factory Default —
Standard
Changeable During Run —
Yes
Continued Stall Period
Program
Protection
Stall
This parameter allows the user to extend the
Over-Voltage
Stall
(
)
and the
Over-Current Stall
(
) time settings.
Direct Access Number — F452
Parameter Type —
Numerical
Factory Default —
0.0
Changeable During Run —
Yes
Minimum — 0.0
Maximum — 1.00
Units — Seconds
Stall Prevention During Regeneration
Program
Protection
Stall
This parameter
Enables/Disables
the
Over-Voltage
Stall
and the
Over-
Current Stall
(
) function during regeneration only. Application-specific
conditions may occur that warrant disabling the
Stall
function during
regeneration.
Settings:
0 — With Stall Prevention
1 — Without Stall Prevention
Direct Access Number — F453
Parameter Type —
Selection List
Factory Default —
With Stall
Prevention.
Changeable During Run —
Yes
Current Differential Gain
Program
Special Control
Special Parameters
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 —
Yes
Minimum — 0.00
Maximum — 327.6
VI/II Bias Adjust
Program
Frequency Setting
Speed Reference Setpoints
VI/II
This parameter is used to fine-tune the bias of the
VI/II
input terminals.
Note:
See note on
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 —
Yes
Minimum — 0.0
Maximum — 255
