Manual Torque Boost 1
Program Fundamental 1
The Manual Torque Boost 1 function is used to increase the low frequency
torque for high-inertia loads by increasing the output voltage at frequencies below
½ of the Base Frequency 1 (F014) setting.
The value programmed as a boost percentage establishes an output voltage vs.
output frequency relationship to be used to start the motor or to provide smoother
operation.
Note:
Setting an excessive Torque Boost level may cause nuisance
tripping and mechanical stress to loads.
Soft Stall Selection
Program Protection
This parameter is used to protect the motor from an over-current condition by
automatically reducing the output frequency when approaching an overload
condition.
The Overload/Stall setting and the type of motor being used is selected here to
better match the application.
This parameter setting may extend the Over-Voltage Stall time settings.
Settings:
0 — Overload Trip without Stall
1 — Overload Trip with Stall
2 — No Overload without Stall
3 — Stall Only
4 — V/f Motor-Overload without Stall
5 — V/f Motor-Overload with Stall
6 — V/f Motor-No Overload without Stall
7 — V/f Motor-Stall Only
