Reference types and processing

The drive can accept a variety of references in addition to the conventional analog
input and control panel signals.
• The drive reference can be given with two digital inputs: One digital input
increases the speed, the other decreases it.
• The drive can form a reference out of two analog input signals by using
mathematical functions: addition, subtraction, multiplication and division.
• The drive can form a reference out of an analog input signal and a signal received
through a serial communication interface by using mathematical functions:
addition and multiplication.
• The drive reference can be given with frequency input.
• In external control location EXT1/2, the drive can form a reference out of an
analog input signal and a signal received through Sequence programming by
using a mathematical function: addition.
It is possible to scale the external reference so that the signal minimum and
maximum values correspond to a speed other than the minimum and maximum
speed limits.
