Controlling the Speed through a Voltage Input
Set parameter b1-01 to 1 (0 default). Through this, the analogue input termi-
nal A2 becomes the main frequency reference.
Set DIP switch S1 to the bottom position V (voltage).
DIP switch S4 must remain at its default position: top, multifunction input.
Set parameter H3-09 to 0. Through this, the input signal type is set to “0-10
VDC with lower limit”. Make sure that parameter H3-10 has been set to the
default value 0.
Connect the control voltage to terminals A2 and AC. 0 to 10 V, 0 V corre-
sponds to 0 Hz, 10 V corresponds to 100 Hz, linear increase.
Controlling the Speed through a Current Input
Set parameter b1-01 to 1 (0 default). Through this, the analogue input termi-
nal A2 becomes the main frequency reference.
DIP switch S1 must be at its default position: top, position I.
DIP switch S4 must be at its default position: top, multifunction input
Parameter H3-09 must be at its default value 2, input signal type “4-20 mA”).
Make sure that parameter H3-10 has been set to the default value 0.
Connect the control current to terminals A2 and AC. 4 to 20 mA, 4 mA cor-
responds to 0 Hz, 20 mA corresponds to 100 Hz, linear increase.
Fit the cover of the frequency converter again.
Always operate the pump with its cover in place!
