7.3.7 Positioning
458 Operation Mode (Positioning)
Positioning is effected in operation mode "Reference positioning" via specification of the position dis-
tance.
Reference positioning uses a digital reference signal on digital input IN1D (terminal X11.4) for posi-
tioning the drive independent of the speed.
The function "Reference positioning" is available in configurations 110, 410 and 610 and is activated
by selecting operation mode 1 for parameter
Operation Mode 458.
Positioning switched off.

Reference positioning
Reference positioning via definition of the positioning distance
(revolutions). The reference point is identified via digital input
459 Signal source
Reference positioning is started with the status change of the reference signal at digital input IN1D
(terminal X11.4). Logic evaluation can be selected via the parameter signal source.
1 -
IN1D, falling edge
The positioning starts with the change of the logic signal from
1 (High) to 0 (Low) at the reference point.
11 -
IN1D, rising edge
The positioning starts with the change of the logic signal from
1 (Low) to 0 (High) at the reference point.
21 -
IN1D, rising/falling edge
Positioning is started with a signal change at the reference
point.
If the digital input IN1D is used for the reference signal, it must be checked if this input is linked to
another function. By default, digital input IN1D has the function "Start clockwise" (Parameter
Start
clockwise
68).
Do not use digital input IN1D for positioning and a stopping behavior (parameter
Operation mode
630) at the same time.
460 Positioning distance
The feedback of the current position is referred to the revolutions of the motors relative to the time of
the reference signal. The positioning accuracy depends on the current
Actual Frequency 241, the
Deceleration (clockwise) 421, the No. of pole pairs 373, the selected Positioning distance 460 and
the configured control behavior.
The distance between the reference point and the required position is to be defined in motor revolu-
tions. The calculation of the distance covered is done with the selected
Positioning distance 460 ac-
cording to the application.
The setting 0.000 U for the
Positioning distance 460 causes an immediate stop of the drive according
to the selected stopping behavior for
Operation mode 630.
