4 Technical description
4.1 Input and output signals
Connection
Supply
PIN 3, PIN 31
and PIN 35
Power supply (see technical data)
PIN 4, PIN 32
and PIN 36
0 V (GND) connection.
Caution
, PIN 4 is connected internally to PIN 11 (and also possibly to PIN 12 depending on
the model). These connections serve as a reference potential for the analogue sensor or
demand value signals.
Connection
Analogue signals
PIN 13
Analogue position actual value (X1), range 0… 100% corresponds to 0… 10V or 4… 20 mA
PIN 14
Analogue position actual value (X2), range 0… 100% corresponds to 0… 10V or 4… 20 mA
PIN 15 / 16
Analogue differential output for activation of the axis 1:
-100...100% corresponds to -10...10V.
PIN 19 / 20
Analogue differential output for activation of the axis 2:
-100...100% corresponds to -10...10V.
Connection
SSI sensors
PIN 37-40
PIN 33, 34
Interface 1 to the SSI sensor. RS422 interface and power supply
PIN 41-44
PIN 47, 48
Interface 2 to the SSI sensor. RS422 interface and power supply
Connection
Digital inputs and outputs
PIN 8
Enable input:
This digital input signal initializes the application. The signal will be approved in connection
with the software enable the corresponding axis.
PIN 2
Synchronous error output (only active in synchronous mode):
ON:
Slave axis within the error window (GL:E)
OFF:
Slave axis outside the error window (GL:E)
PIN 1
READY output:
ON:
The module is enabled; there are no discernable errors.
OFF:
Enable (PIN 8) is disabled or an error (sensor or internal error) has been detected.
