Lenze 8600 series - Features of Setpoint; Setpoint Input with Master Current

3.4 Features of setpoint 1
An analog entry of setpoint 1 is possible via input Xl/terminal 8,
otherwise it is entered via the keypad or the LECOM interfaces.
This depends on the selected operating mode (Cool). The
configuration determines whether the input is unipolar, bipolar, or
independently of the operating mode, a digital frequency input.
With terminal control you tan read setpoint 1 under code C046.
Under code Cl72 you tan select whether the setpoint is to be
displayed in per cent (related to fdma) or as absolute value.
With control via keypad or LECOM you tan enter under Cl 72 how
you Want to enter setpoint 1, in per cent related to
fdmax or as
absolute value in Hz.

INFO: adjustable range: -fdmax bis +fdmax
Absolute setpoints which are higher than the maximum field
frequency, are internally limited to the maximum field frequency
(CO1 1).
3.4.1 Setpoint input with master current
For analog setpoint input with master current, first Change the switch
setting of S1/4 on the control board (see page 31). CO34 is used to
determine the setting range.
