T074 [Analog In 2 Lo]
Related Parameter(s): P034 , P038 , T072 , T073 , T075
T076 , A152 , A153
Stop drive before changing this parameter.
Sets the analog input level that corresponds to P034 [Minimum Freq].
Analog inversion can be accomplished by setting this value larger than T075 [Analog In 2 Hi].
Important: If analog inversion is implemented the drive will go to maximum frequency in the event the
analog input is lost. It is strongly recommended to activate T072 [Analog In 1 Loss] to protect from this
potential occurrence.

Stop drive before changing this parameter.
Sets the analog input level that corresponds to P035 [Maximum Freq].
Analog inversion can be accomplished by setting this value smaller than T074 [Analog In 2 Lo].

T076 [Analog In 2 Loss]
Related Parameter(s): T055 , T060 , T065 , T073 , T074 , T075
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
T074 [Analog In 2 Lo]
to a minimum of 20% (i.e. 2 volts).
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].
