Manual Torque Boost 1
Program Fundamental Motor Set 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.
Motor Overload Protection Configuration
Program Protection Overload
This parameter is used to enable the Soft Stall feature which protects the motor
from an over-current condition by reducing the output frequency during a
temporary increased current requirement from the load.
A V/f motor may be specified here along with the Overload Stall to better
match the ASD to the application.
This parameter setting may extend the Over-Voltage Stall time settings.
Settings:
0 — Motor Overload Trip without Soft Stall
1 — Motor Overload Trip with Soft Stall
2 — Without Motor Overload Trip or Soft Stall
3 — Soft Stall Only
4 — V/f Motor Overload Trip without Soft Stall
5 — V/f Motor Overload Trip with Soft Stall
6 — V/f Motor without Overload Trip or Soft Stall
7 — V/f Motor Soft Stall Only
