Speed Limit (torque=0) Center Value
Program Torque Torque Speed Limiting
This parameter provides a value to be used as the Speed Limit (torque=0)
Center Value Reference
setting if the F431 setting is selected at F430.
Direct Access Number — F431
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — Maximum Freq. (F011)
Units — Hz
Speed Limit (torque=0) Band
Program Torque Torque Speed Limiting
The system has the ability to limit the amount that the speed may vary as a
function of a changing load while operating in the Torque Control mode. This
parameter sets a plus-or-minus value (range) for the Speed Limit Torque
Level (
F431).
Direct Access Number — F432
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — Maximum Freq. (F011)
Units — Hz
Time-Based Alternation Pump Number
Program Virtual Linear Pump Time-Based Alternation
During Time-Based Alternation operation, this parameter is used to assign an
identifying number to an ASD/pump combination.
The identifying number is used to assign the virtual priority Lead and Lag
assignments.
The maximum number is limited to the user-assigned number at parameter
F437.
Note: This parameter is not associated with nor affected by the setting
of
F802.
Direct Access Number — F434
Parameter Type — Selection List
Factory Default — 1
Changeable During Run — Yes
Minimum — 1
Maximum — F437 Setting
Rotation in Specified Direction ONLY
Program Torque Torque Speed Limiting
This parameter Enables/Disables the Forward Run or Reverse Run mode.
If either direction is disabled, commands received for the disabled direction will
not be recognized.
If both directions are disabled, the received direction command will determine
the direction of the motor rotation.
Settings
0 — Disabled
1 — Enabled
Direct Access Number — F435
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Time-Based Alternation Total Number of ASDs
Program Virtual Linear Pump Time-Based Alternation
This parameter lists the number of ASDs registered within the system.
This parameter setting is used as the Maximum setting for parameter F434.
Direct Access Number — F437
Parameter Type — Numerical
Factory Default — 2
Changeable During Run — Yes
Minimum — 2
Maximum — 32
