Description
Pulses that are proportional to an analog signal can be evaluated
with this setting via DIN 2 and DIN 3. The function of this signal is
determined in parameter P400 [-06] or [-07].
The conversion of 0-10 V to pulses can be carried out via
customer unit SK CU/TU4-24V-... An analog input and a pulse
output (ADC) are available with this module.
In setting { 28 } reversal of the direction of rotation takes place
with an analog value of <5 V.
(please see chapter 3.2.4 "Potentiometer adapter, SK CU4-POT")
The release signal is provided by the Simple Setpoint Box
(setpoint unit) SK SSX-3A, whereby the unit must be operated in
IO-S mode.  BU0040
Switching the PID controller/process controller function on and off
(high = ON)
Blocks the >Enable right/left< via a digital input or bus actuation.
Does not depend on the actual direction of rotation of the motor
(e.g. following negated setpoint).
Activates the evaluation of the zero track of a rotary encoder.
Synchronization to zero pulse after every enable command.
Activates the evaluation of the zero track of a rotary encoder.
Synchronization to zero pulse after first enabling after "power on".
This control function provides an alternative to enable R/L
(01/02), for which a maintained signal is required.
Only a momentary signal is required here to trigger the function.
The VFD can therefore be controlled entirely with pushbuttons.
In combination with enable R/L the output frequency can be
continuously varied. To save a current value in P113, both inputs
must be at a High voltage for 0.5 s. This value then applies as the
next starting value for the same direction of rotation (Enable R/L)
otherwise start at f .
MIN
Binary coded digital inputs to generate up to 15 fixed frequencies.
(P465: [-01] ... [-15])
BU0210
The brake is automatically released by the variable frequency
drive (automatic brake control) if this digital input has been set.
The brake is only released of the digital input is set.
