Toshiba H9 F016 F017, Manual Torque Boost, Motor Overload Protection Configuration

F016 F017

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.

Direct Access Number — F016

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — Yes

Minimum — 0.0

Maximum — 30.0

Units — %

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

Direct Access Number — F017 Parameter Type — Selection List Factory Default — O/L Trip No Stall Changeable During Run — Yes
