When set to DISABLED, the Control Screen menu is hidden.

When set to AUTO, the contents of the Control Screen menu depends on the sequencing mode of the drive, (local, remote or
communications).

When set to CUSTOM, the contents of the Control Screen may be defined by writing parameter numbers to the elements of the

1352

Control Screen

array. Note that the contents of the

1352

Control Screen

array are not saved in non-volatile memory, so the values

need to be initialised following a power-on reset.

Functional Description

The Soft Menus group of parameters are used to populate the associated menus depending on the associated application, (Control Screen, Setup
and Monitor) or the requirements of the location, (Favourites). The contents of the Setup and Monitor menus may only be set by the application itself.
The contents of the Favourites menu may be set by writing to the parameters in the Favourites array. Alternatively parameters may be added to or
removed from the Favourites menu by use of the GKP. Navigate to the parameter of interest and hold the OK key until the attributes screen is
shown. If the parameter is not already in the Favourites menu a pressing Soft Key 2 adds the parameter to Favourites. This operation is indicated by
the icon

. Similarly, to remove a parameter from Favourites, navigate to the parameter in the Favourites menu then press OK until the

parameter attributes are shown. Remove the parameter from Favourites by pressing Soft Key 2. This operation is indicated by the icon

Parameters::Motor Control::Spd Direct
Input

0:NONE
1:ANIN1
2:ANIN2

ALWAYS

The direct input to the speed loop is an analog input which is sampled synchronously with the speed loop. This ensures that the speed
loop always has the most up-to-date value of the input, allowing it to respond faster. Either of the two analog inputs can be selected as
the direct input. If NONE is selected, the input is set to zero. When not in use, it should be disabled by selecting NONE.

Parameters::Motor Control::Spd Direct

Parameters::Motor Control::Spd Direct
Input

-600.00 to 600.00

ALWAYS

This limits the lower value of the Direct Input.

Functional Description

The Drive is commanded to run the motor at a certain speed, which is derived from various sources, such as comms, analog inputs, commands from
the keypad, etc. Most of these are derived from sources which respond relatively slowly, eg every 1ms. For processes which require a faster
response, the direct input is provided. This is an analog input which is sampled synchronously with the speed loop, as described above. It is added
on to the other sources of speed command to give a total speed command.

Parameters::Motor Control::Spd
Loop Settings

FALSE

ALWAYS

When set to TRUE, and the drive is in Torque Control mode, this parameter prevents operation outside the speed limits defined in Spd
Demand Pos Lim and Spd Demand Neg Lim. The torque setpoint is compensated if the motor speed reaches these speed limits.

Functional Description

The speed error (speed demand minus speed feedback) is calculated and processed via a proportional + integral (PI) controller. The output of the
PI controller is a torque demand, which is passed directly to the torque control feature.

When the drive is in SENSORLESS VEC mode, the speed feedback is calculated from the voltages and currents flowing in the motor, and the motor
model.

Parameter Reference

Stack Inv Time

Parameters::Motor Control::Stack Inv Time

The purpose of the inverse time is to automatically reduce the drive current limit in response to prolonged overload conditions.

For a short time given by Short Overload Time, the drive is able to provide the Short Overload Level

For a long time given by Long Overload Time, the drive is able to provide the Long Overload Level

These 2 protections work in parallel, the output limit current is the maximum value if

Inv Time Active

= False. If

Inv Time Active

= True, the

current limit is determined by Long Overload Level

the current limit is not yet ramped down. If already ramped down, the current limit is due to the long overload.

When the maximum overload value is reached, the inverse time current limit is ramped down. The rate at which the inverse time current limit is
ramped to the Inv Aiming Point is defined by

Inv Time Down Rate

. When the overload condition disappears, the inverse time current limit is ramped

up. The rate at which the inverse time current limit is ramped to the maximum value is defined by

Inv Time Up Rate.
