Description

Analog Inputs

Sets the speed command when 10V is input, as a
percentage of the maximum output frequency (E1-04).
Sets the speed command when 0V is input, as a
percentage of the maximum output frequency (E1-04).
Selects the signal level of terminal A2.
0: 0 - 10VDC (switch S1-2 must be in the off position)
2: 4 - 20 mA (switch S1-2 must be in the on position)
Selects what effect the aux terminal has on the Drive.
0: Frequency Bias - 0 - 100% bias
2: Aux Reference
B: PI Feedback
D: Frequency Bias 2 - 0 - 100% bias
E: Motor Temperature - See parameters L1-03 & L1-04
16: PI Differential
1F: Not Used
Sets the percentage when 10V (20mA) is input.
Sets the percentage when 0V (4mA) is input.
Used to "smooth" out erratic or noisy analog input
signals.
Determines which terminal will be the main reference
source.
0: Main Fref TA1 - Terminal TA1 is the main speed
command and Terminal TA2 is the Aux speed
command.
1: Main Fref TA2 - Terminal TA2 is the main speed
command and Terminal TA1 is the Aux speed
command.
Only effective when H3-09 is set to 2 "Aux Reference".
