T072 [Analog In 1 Loss]

T071 , A152
Stop drive before changing this parameter.
Selects drive action when an input signal loss is detected. Signal loss is defined as an analog signal
less than 1V or 2mA. The signal loss event ends and normal operation resumes when the input signal
level is greater than or equal to 1.5V or 3mA. If using a 0-10V analog input, set
T070 [Analog In 1 Lo]
to a minimum of 20% (i.e. 2 volts).
The drive will fault on an F29
Analog Input Loss when the analog signal is lost if this parameter and
A152 [PID Ref Sel] are both set to an option other than 0 “Disabled”.
Options 0 “Disabled” (Default)
1 “Fault (F29)” F29 Analog Input Loss
2 “Stop” Uses P037 [Stop Mode]
3 “Zero Ref” Drive runs at zero speed reference.
4 “Min Freq Ref” Drive runs at minimum frequency.
5 “Max Freq Ref” Drive runs at maximum frequency.
6 “Int Freq Ref” Drive runs at A143 [Preset Freq 0].

A152
Sets the analog input signal mode (0-20mA, 4-20mA, 0-10V, -10 to +10V). This parameter must match
DIP Switch AI2 setting on the control board.

Setting 3 is only available on [Analog In 2 Sel]. Input 2 is isolated and supports a bi-polar input, so
that setting 3 determines if the voltage input is enabled for bipolar control. If bipolar is selected, P034
[Minimum Freq] and T074 [Analog In 2 Lo] are ignored. If input 2 is set up for current control, Bipolar
mode is not possible. If the analog input is inverted ([Analog In 2 Lo] > [Analog In 2 Hi]), Bipolar mode
is disabled and this input uses unipolar control only (negative values are treated like zero).
