Manual Torque Boost; Motor Overload Protection Configuration - Toshiba H9 Installation And Operation Manual

F016

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 protect the motor from an overcurrent 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 Overvoltage Stall time settings.
This parameter may be affected by the setting of the Power Running Stall
Continuous Trip Detection Time (F452).
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
