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
(
) 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 protect the motor from an over-current condition. The
type of motor being used and the
Overload Stall
setting is selected here to
better match the application.
This parameter setting may extend the
Over-Voltage
Stall
time settings.
This parameter may be affected by the setting of the
Power Running Stall
Continuous Trip Detection Time
Parameter
(Power Running Stall Continuous Trip Detection Time)
setting
may affect the performance of this parameter setting.
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
