Reference types and processing
In addition to the conventional analogue input signal and control panel signals, the
drive can accept a variety of references.
• The drive reference can be given with two digital inputs: One digital input
increases the speed and the other decreases it.
• The drive accepts a bipolar analogue speed reference. This feature allows both
the speed and the direction to be controlled with a single analogue input. The
minimum signal is full speed reversed and the maximum signal is full speed
forward.
• The drive can form a reference from the signal received through a communication
interface.
It is possible to scale the external reference so that the minimum and maximum
values of the signal correspond to speeds other than the minimum and maximum
speed limits.
