Direction Selection
Inputs
Sets the function of inputs programmed as Up and Down according to
US04 Control Type. In addition, the Brake Control output condition can
be assigned to direction or speed inputs. Direction Selection and Brake
Function options can be selected in combination.
Setting: Description:
Direction Selection
Up & When Up and Down functions are programmed to digital
Down inputs (LI04-11), if either the digital input is selected OR
Inputs the direction bit in the Control Word (serial speed control,
FB01), then the direction bit will be set.
Up/Down inputs control direction or start. If both Up and
Down are signaled, a 'Direction Selection Failure' fault
will occur unless in UPS Operation mode; refer to LI04
UPS Operation for details*
Down The Up direction is automatically selected internally
Input Only when a speed input is given and the digital input for the
down direction will have priority. When the speed input is
dropped at the floor, the direction is internally dropped.
This function is not supported in Analog or Serial Speed
Control modes. The (LO05-20) output function 'Brake
Control' cannot be used with this selection.
Up & When Up and Down functions are programmed to digital
Down inputs (LI04-11), the digital hardware input AND the
AND Control Word (serial speed control, FB01) direction bit
Serial must be set for the direction to be active. The hardware
Control direction must match the software direction. If both Up
Word and Down are signaled, a 'Direction Selection Failure'
fault will occur.*
Although the actual direction is determined by the signed
serial speed command (FB02), the sign must match the
direction when utilizing LC01 with Synthetic Pretorque (5).
Brake Function
Function When an output (LO05-20) is programmed as 'Brake
by Control' , the output will signal to set the brake when the
Direction direction input has dropped and the speed command
Inputs has reached zero.
Function When an output (LO05-20) is programmed as 'Brake
by Speed Control' , the output will signal to set the brake when
Selection the speed inputs have all been dropped and the speed
command has reached zero.
Default = Up and Down Inputs + Function by Direction Inputs (0)
