Supply
Power supply (see technical data)
0 V (GND) Power supply (ground).
PWM output
Current controlled PWM outputs for solenoid A.
Current controlled PWM outputs for solenoid B.
Analogue signals
Command signal input (WA), range +/- 10 V or 4...20 mA, scalable
Feedback signal input (X), range 0... 10 V or 4... 20 mA, scalable
0 V (GND) reference for the signal inputs
8 V reference voltage output
Digital inputs and outputs
Enable Input:
This digital input signal initializes the application and the power stage.
READY output:
ON:
Module is ready, no errors are detected
OFF:
ENABLE is deactivated or an error was detected.
Description of the LED function
1.
Chasing light (over all LEDs): The bootloader is active. No normal functions are pos-
sible.
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 the data have to be saved with the SAVE command
or the corresponding button in the WPC.
Identical to the READY output.
OFF:
No power supply or ENABLE is not activated
ON:
System is ready for operation
Flashing:
Error detected
Current to the solenoid A; the intensity is proportional to the actual output current.
Current to the solenoid B; the intensity is proportional to the actual output current.
