ABB ACS850 - Programmable Analog Inputs

Program features 41
when the pressure falls under the predefined minimum level and the wake-up delay
has passed.
Settings
Parameter group 27 Process PID (page 139).
The PID control macro can be activated from the control panel main menu by
selecting ASSISTANTS – Firmware assistants – Application Macro – PID control. See
also page 56.
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.
