Description
ADR
Analogue Rotation with Direction Definition
Rotary movement with a set acceleration and maximum velocity. The rotation direction and the
rotation velocity setpoint is set via Analogue Input "AI 1". The signal can be supplied manually or
by a higher-level control system.
Voltage interval of 0 V to 10 V
-
0 V to 5 V motor rotating anti-clockwise
-
5 V to 10 V motor rotating clockwise
Maximum velocity at 0 V or 10 V
Voltage interval of -10 V to +10 V
-
-10 V to 0 V motor rotating anti-clockwise
-
0 V to +10 V motor rotating clockwise
Maximum velocity at -10 V or +10 V
The rotary movement is executed continuously at a certain velocity after the setpoint has been set.
The movement is only stopped because of one of the following actions/commands:
-
The value of the analogue setpoint is set to a standstill
-
A "Stop" command
-
A "Quick Stop" command
-
DI 7 “Enable” is revoked
An "Error" occurs
APS
Analogue Positioning
Movement with a set acceleration and maximum velocity. The position is defined by a voltage
applied to Analogue Input "AI 1" and the selected voltage interval. The signal can be supplied
manually or by a higher-level control system.
Voltage interval of 0 V to 10 V
-
Minimum position at 0 V
-
Maximum position at 10 V
Voltage interval of -10 V to 10 V
-
Minimum position at -10 V
-
Maximum position at 10 V
After the target position is reached nor “Ready” signal at Digital Output DO1 will be emitted with
Analogue Positioning. In this case the “Target Reached” information can be obtained with the
negative edge of Digital Output DO2 “Active” instead.
Theoretically, a positioning accuracy of 0.244 mm is available with the 12-bit resolution and a travel
distance of, for example, 1000 mm.
In comparison, a positioning accuracy of 0.0024 mm is available for a travel distance of 100 mm.
This accuracy is, however, reduced when real circumstances are considered due to interference
and other occurrences. As a result, deviations may occur depending on the environment and the
used linear axis.
It is also important to consider the situation to which this accuracy is applied.
If a new position is to be approached in the immediate vicinity, the configurable dead bands and
filter times of the analogue input play a role (
(p. 50)).
Thus, it may not be possible to reach a target position from a too near distance from the actual
position.
If, however, the same target position is approached from a greater distance, it is quite possible to
reach it.
