Variable speed drives

Altivar Machine ATV320

Option: speed monitoring module

Presentation

The

VW3A3620 speed monitoring module is recommended for hoisting

applications.

This module helps to detect undesired load slip on hoisting applications by means

of an external encoder. The variable speed drive manages the load slip according to

the configuration parameters.

Functions

The load slip frequency threshold represents the difference between the speed

feedback and the output frequency.

The load slip detection level can be adjusted so that the function can be used

more efficiently.

The load slip direction check allows the variable speed drive to check that

movement is initiated in the desired direction.

The load slip detection duration can be configured in order to optimize the use of

the function according the changing mechanics.

The

VW3A3620 speed monitoring module helps to ensure that the actual motor

speed is within the acceptable threshold settings and that movement is in the

desired direction.

The variable speed drive will trigger a warning and the motor will stop either with a

freewheel stop or via the brake logic control function (depending on the

configuration) in the following cases:

if the actual speed is different from the permitted speed reference threshold and

this reaches the defined duration, or

if the direction of motor rotation is not as expected
