Via parameters
range is scaled if operation mode 2 or 3 is selected for parameter
Mode
the signal sources for determining the reference value are selected. With the signal
source selected, e.g. an analog signal at the multifunction input MFI1A, the gear factor
can be changed during operation.
No.
687 Analog Factor Max.
688 Analog Factor Min.
Signal flow diagram for scaling the gear factor via the reference percentage source:
Example:
In an application, a Slave drive is to follow a Master drive, with the speed of the Slave
having to be increased continuously without changing the speed specified by the mas-
ter. The gear factor control is to be done using an analog voltage signal (0...10 V).
