Low Level Low, Fault if input signal below preset trip level.
High Level High, Fault if input signal above preset trip level.
Description The analog input is the reference input for a starter configured as a Phase Controller or Current Follower. In
addition, the Analog Input Trip parameter allows the user to set a "High" or "Low" comparator based on the
analog input. If the type is set to "Low", then a fault occurs if the analog input level is below the trip level for
longer than the trip delay time. If the type is set to "High", then a fault occurs if the analog input level is
above the trip level for longer than the trip delay time. This function is only active when the motor is running.
This feature can be used in conjunction with using the analog input as a reference for a control mode in order
to detect an open 4-20mA loop providing the reference. Set the Analog Input Trip Type parameter to"Low"
and set the Analog Trip Level parameter to a value less than (<) 20%.

Range 0 – 100 % (Default: 50)
Description The Analog Input Trip Level parameter sets the analog input trip or fault level.
This feature can be used to detect an open 4-20mA loop by setting the Analog Input Trip Type (I/O 16)
parameter to "Low" and setting the Analog Input Trip Level (I/O 17) parameter to a value less than (<) 20%.

NOTE: The analog input trip level is NOT affected by the Analog Input Offset or Analog Input Span
parameter settings. Therefore, if the trip level is set to 10% and the Analog Input Trip Type parameter is set
to "Low", a fault occurs when the analog input signal level is less than (<) 1V or 2mA regardless of what the
Analog Input and Analog Input Span parameters values are set to.
