Preset speeds

This is used to switch preset speed references.

Choice of between two and eight preset speeds.

Enabled by means of between 1 and 4 logic inputs.

Thepresetspeedsareadjustableinincrementsof0.1Hzfrom0Hzto400Hz.

They take priority over the reference given by the active control channel (analog

input or the navigation button).

The speed obtained with inputs

Llx and LIy at state 0 is LSP or the

speed reference, depending on

the level of analog input AI1.

Factory settings:

speed: LSP (low speed or

reference)

speed: 10 Hz

speed: 25 Hz

speed: 50 Hz

Example of operation with 4 preset speeds

Three additional high speeds

ThesethreeadditionalhighspeedsaredenedbyHSP2,HSP3andHSP4.

They are used to select 2 or 4 high speeds (HSP/HSP2 or HSP/HSP2/HSP3/HSP4).

Enabling 2 or 4 high speeds requires the use of 1 or 2 logic inputs respectively.

Control modes

There are several control and reference channels which can be independent.

Commands (forward, reverse, etc.) and speed references can be sent via the

following channels:

v Terminals (logic and analog I/O)

v Local mode (STOP/RESET and RUN buttons and the navigation button)

v Remote display terminal

v Modbus

serial link

The control and reference channels can be separate (separate mode).

Example: The Run/Stop commands come from the terminals and the speed

reference comes from the Modbus serial link.

The control and reference channels can also come from the same source

(not separate mode).
