Programming 81
Function: Hand Mode Fref
Setting: 52
The analog output level will correspond to the Speed Command input chosen by the b1-12 parameter regardless of whether the
Drive is being operated in the Hand mode or not. 100% will be equivalent to the maximum frequency of the Drive (E1-04).
Function: PI Feedback 2
Setting: 53
The analog output level will correspond to the analog input to the Drive’s A1 terminal during PI Differential operation but the
analog output will not function during normal PI operation.
H4-02 Terminal FM Gain Setting
Setting Range: 0.0 to 1000.0%
Factory Default: 100.0%
Refer to parameter H4-03 for description details.
H4-03 Terminal FM Bias Setting
Setting Range: -110.0% to +110.0%
Factory Default: 0.0%
The gain and bias parameters for the analog outputs of the Drive allow the programmer to customize the output signal for the
equipment connected to the output. The analog outputs are adjustable over a range of 0-10 Vdc. The gain settings for the
analog outputs determine the output voltage level that will be equivalent to 100% of the Monitor Function Level. A gain
setting greater than 100% will produce 10Vdc on the analog output when the monitor function is less than 100%.
For example, if H4-02= 150%, then the FM analog output will produce 6.7Vdc when the assigned output function initially
reached the 100% level.
