6.1.3 Current output (non safety related)
The current output can be set to speed or position dependent on the menu and must be
activated before use.
6.1.3.1
Configuring the position-dependent current output
To configure the position-dependent current output it is nec-
essary to enter 2 position values, which must be within the
system limits.
The smaller position value is assigned current I
min
= 4 mA and
the larger position value I
max
= 20 mA.
The following restriction applies:
•
Pos1 < Pos2
If the current position is outside of the defined position range,
the current output is switched to high impedance (I = 0 mA).
(Factory setting).
Alternatively, it is possible to select a setting to take effect in
the event the value falls below or exceeds the determined po-
sition range 4 mA or 20 mA.
6.1.3.2
Configuring the speed-dependent current output
To configure the speed-dependent current output it is neces-
sary to enter the speed
n20 mA
. When at a standstill a current of
4 mA flows.
The following constraint applies:
•
n
20 mA
< (approved mechanical speed -10%)
If the speed exceeds the speed range (n
current
> n
20 mA
), the cur-
rent output is switched to high resistance
(I = 0 mA) – (factory setting).
Alternatively, it is possible to select a setting to take effect in
the event the value exceeds the determined position range
20 mA
.
6.1.4 Configuring the incremental output (non safety-related)
The incremental output is optional. To configure the incre-
mental output it is possible to select a pulse rate of 1024 or
4096
(factory setting: 4096).
