Supply
Power supply (see technical data)
0 V (GND) connection.
Analogue signals
Command value (WA), signal range 0... 10 V or 4... 20 mA, scalable
Feedback value (X), signal range 0... 10 V or 4... 20 mA, scalable
0 V (GND) connection for analogue signals
8V reference voltage output
Solenoids
PWM output solenoid B
PWM output solenoid A
Digital inputs and outputs
ENABLE input:
Generally enabling of the application. Activates controller, power stage and READY.
FIXCURRENT input:
ON:
Direct control of the power stage via the FIXCURR parameter.
OFF:
Swivel angel control is active (normal state).
READY output:
ON:
The module is enabled; there are no discernable errors.
OFF:
ENABLE is not available or an error has been detected.
Description of the LED function
Identical to the READY output.
OFF:
No power supply or ENABLE is not activated
ON:
System is ready for operation
Flashing:
Error discovered
Intensity of the current at solenoid A
Intensity of the current at solenoid B
1.
Chasing light (over all LEDs): The bootloader is active. No normal functions are
possible.
2.
All LEDs flash shortly every 6 s: An internal data error was detected and corrected
automatically! The module still works regularly. To acknowledge the error the module
has to be cycle powered.
Both yellow LEDs flash oppositely every 1 s: The nonvolatile stored parameters are in-
consistent! To acknowledge the error, data has to be saved with the SAVE command or
the corresponding button in the WPC.
