4 Technical description
4.1 Input and output signals
4.2 LED definitions
LEDs
Description of the LED function
GREEN
Identical to the READY output.
OFF:
No power supply or ENABLE is not activated
ON:
System is ready for operation
Flashing:
Error discovered
YELLOW A
Intensity of the solenoid current
GREEN +
YELLOW A
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.
YELLOW A +
YELLOW B
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.
Connection Supply
PIN 7
Power supply (see technical data)
PIN 8
0 V (GND) connection.
Connection
Analogue signals
PIN 9 / 10
Command value (WA), signal range
0… 10 V or 4… 20 mA, scalable, alternatively PWM
signal
PIN 13 /14
Feedback value (X), the actual speed is read in via a pulse transmitter (12 / 24 V)
PIN 11
0 V (GND) connection for analogue signals
PIN 12
8V reference voltage output
Connection
Solenoids
PIN 2 / 1
PWM output solenoid B
PIN 3 / 4
PWM output solenoid A
Connection
Digital inputs and outputs
PIN 15
ENABLE input:
Generally enabling of the application.
Erases error messages, activates the power stage and the READY signal.
PIN 6
START (DIR) input
:
ON:
Closed loop control mode, the PID controller is activated
OFF:
Open loop amplifier mode, pure power amplifier
PIN 5
READY output:
ON:
The module is enabled; there are no discernable errors.
OFF:
ENABLE is not available, no supply or an error has been detected.
