Direct Access Parameter Information
Q9 Plus ASD Install/Op Manual
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 pro-
tects the motor from an over-current condition by reducing the
output frequency during a temporary increased current require-
ment 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

Factory Default — Motor Over-
load Trip with Soft Stall
Changeable During Run — Yes
