Description
Programmable protection functions
Defines the drive response if the analog input (AI) signal drops below the
fault limits and AI is used
• as the active reference source (group
• as the process or external PID controllers' feedback or setpoint source

active.
3021 AI1 FAULT LIMIT sets the fault limits
Protection is inactive.
The drive trips on fault AI1 LOSS
Fault limit is defined by parameter
The drive generates alarm
the value defined by parameter
defined by parameter 3021
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
The drive generates alarm
the level the drive was operating at. The speed is determined by the average
speed over the previous 10 seconds. The alarm limit is defined by parameter
3021 AI1 FAULT LIMIT.
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
Selects an interface for an external fault 1 signal.
