Programmable analog inputs

The drive has two programmable analog inputs. Each of the inputs can be
independently set as a voltage (0/2...10 V or -10...10 V) or current (0/4...20 mA)
input by a jumper on the JCU Control Unit. Each input can be filtered, inverted and
scaled. The number of analog inputs can be increased by using FIO-xx I/O
extensions.
