4.3.3 Input and output signals
Connection Supply
PIN 7 Power supply (see technical data)
PIN 8 0 V (GND) Power supply (ground).
Connection Reference voltages output
PIN 12 Reference output voltage (8 V).
Connection PWM output
PIN 3 / 4 Current controlled PWM outputs for solenoid A.
PIN 1 / 2 Current controlled PWM outputs for solenoid B.
Connection Analogue input signals
PIN 9 / 10 Command signal (W), range -
100…100 % corresponds with -10…10 V or 4…20 mA, scalable.
PIN 11 0 V reference for the signal inputs (potential from PIN 8).
Connection Digital inputs and outputs
PIN 15 Enable Input :
General enabling of the application.
PIN 6
S1 input:
Function depends on parameter PIN:6 (USCALE/RAMP).
OFF: Output current depends on parameter USCALE; ramp function is deactivated.
ON: Output current is not scaled by USCALE, ramp function is activated.
PIN 5
READY output :
ON: Module is ready, no errors are detected
OFF: ENABLE is deactivated or an error is detected.
