Low frequency torque can be improved by increasing this parameter. Excessive boost levels may however result in high motor current
and increased risk of tripping on Over Current or Motor Overload (refer to section 10.1. Fault Code Messages).
This parameter operates in conjunction with P-51 (Motor Control Mode) as follows:

Boost is automatically calculated according to autotune data.
>0
Voltage boost = P-11 x P-07.This voltage is applied at 0.0Hz, and linearly reduced until P-09 / 2.

Voltage boost = P-11 x P-07.This voltage is applied at 0.0Hz, and linearly reduced until P-09 / 2.

Boost current level = 4*P-11*P-08.
For IM motors, when P-51 = 0 or 1, a suitable setting can usually be found by operating the motor under very low or no load
conditions at approximately 5Hz, and adjusting P-11 until the motor current is approximately the magnetising current (if known) or in
the range shown below.
Frame Size 1: 60 – 80% of motor rated current.
Frame Size 2: 50 – 60% of motor rated current.
Frame Size 3: 40 – 50% of motor rated current.
Frame Size 4: 35 – 45% of motor rated current.

0: Terminal Control.
The drive responds directly to signals applied to the control terminals.
1: Uni-directional Keypad Control.
The drive can be controlled in the forward direction only using the internal keypad, or
an external remote Keypad.
2: Bi-directional Keypad Control.
The drive can be controlled in the forward and reverse directions u using the internal keypad,
or an external remote Keypad. Pressing the keypad START button toggles between forward and reverse.
3: Modbus Network Control.
Control via Modbus RTU (RS485) using the internal Accel / Decel ramps.
4: Modbus Network Control.
Control via Modbus RTU (RS485) interface with Accel / Decel ramps updated via Modbus.
5: PI Control.
User PI control with external feedback signal.
6: PI Analog Summation Control.
PI control with external feedback signal and summation with analog input 1.
7: CAN Control.
Control via CAN (RS485) using the internal Accel / Decel ramps.
8: CAN Control.
Control via CAN (RS485) interface with Accel / Decel ramps updated via CAN.
9: Slave Mode.
Control via a connected Invertek drive in Master Mode. Slave drive address must be > 1.
NOTE
When P-12 = 1, 2, 3, 4, 7, 8 or 9, an enable signal must still be provided at the control terminals, digital input 1.

Enables access to Extended and Advanced Parameter Groups. This parameter must be set to the value programmed in P-37
(default: 101) to view and adjust Extended Parameters and value of P-37 + 100 to view and adjust Advanced Parameters. The code
may be changed by the user in P-37 if desired.
