If the drive should follow an “Auto Set-Point” set by the HOA keypad: Set b1-01 to “0: Operator” (factory default). The Auto
setpoint can then be entered into the U1-01 monitor parameter in the “-DRIVE-” menu.
Setting 0: Operator (HOA keypad)
Using this setting, the frequency reference can be input by:
• switching between the multi-speed references in the d1-
oo
parameters.
• entering the frequency reference on the operator keypad.
This selection will also switch PID setpoint to Q1-01.
Setting 1: Terminals (analog input terminals)
Using this setting, an analog frequency reference can be entered as a voltage or current signal from terminals A1, A2, or A3.
To set the drive to follow an “Auto Setpoint” set by the analog input, set b1-01 to 1 (Terminals) and connect a potentiometer
or external signal to the drive.
Note:
When b1-01 is set to 1 (Terminals) and P5-01 is set to 0 (HAND Mode Reference), the setpoint and the HAND reference are determined
by the external analog signal.
Voltage Input
Voltage input can be used at any of the three analog input terminals. Make the settings as described in
used.
