t091 [Anlg In 0-10V Lo] Related Parameter(s): P043 , t092 , t093
Stop drive before changing this parameter.
Sets the percentage (based on 10V) of input voltage applied to the 0…10V analog input used to represent P043 [Minimum Freq].
Analog inversion can be accomplished by setting this value larger than t092 [Anlg In 0-10V Hi].
If t093 [10V Bipolar Enbl] is set to 1 “Bi-Polar In”, this parameter is ignored.
Values
Default: 0.0%
Min/Max: 0.0/200.0%
Display: 0.1%
t092 [Anlg In 0-10V Hi] Related Parameter(s): P044 , t091 , t093
Stop drive before changing this parameter.
Sets the percentage (based on 10V) of input voltage applied to the 0…10V analog input used to represent P044 [Maximum Freq].
Analog inversion can be accomplished by setting this value smaller than t091 [Anlg In 0-10V Lo].
If t093 [10V Bipolar Enbl] is set to 1 “Bi-Polar In”, the same value applies to positive and negative voltage.
Values
Default: 100.0%
Min/Max: 0.0/200.0%
Display: 0.1%
t093 [10V Bipolar Enbl] Related Parameter(s): t091 , t092
PowerFlex 525 only.
Enables/disables bi-polar control. In bi-polar mode direction is commanded by the polarity of the voltage.
If bi-polar control is enabled, P043 [Minimum Freq] and t091 [Anlg In 0-10V Lo] are ignored.
Options
0 “Uni-Polar In” (Default) 0…10V only
1 “Bi-Polar In” ±10V
PF 525
t094 [Anlg In V Loss] Related Parameter(s): P043 , P044 , A426 , A427
Sets the response to a loss of input. When the 0…10V input (or –10 to +10V) is used for any reference, any input less than 1V is reported as a signal loss. Input must exceed
1.5V for the signal loss condition to end.
If enabled, this function affects any input that is being used as a speed reference, PID reference or PID setpoint in the drive.
Options
0 “Disabled” (Default)
1 “Fault (F29)”
2 “Stop”
3 “Zero Ref”
4 “Min Freq Ref”
5 “Max Freq Ref”
6 “Key Freq Ref”
7 “MOP Freq Ref”
8 “Continu Last”
t095 [Anlg In4-20mA Lo] Related Parameter(s): P043 , t096
Stop drive before changing this parameter.
Sets the percentage (based on 4…20 mA) of input current applied to the 4…20 mA analog input used to represent P043 [Minimum Freq].
Analog inversion can be accomplished by setting this value larger than t096 [Anlg In4-20mA Hi].
