Switching between PWMi and analog output
Mode selection via the PDOs
PWMi mode or analog mode can be selected for operating a proportional valve at socket 7, for example.
• In PWMi mode (default) the coil is controlled directly via a PWM signal. The valve requires no control
electronics.
• In analog mode a current value of 0...20 mA or 4...20 mA is output, via which the control electronics
integrated in the valve controls the valve travel.
The 24V
DC
supply is switched on continuously.
The different modes are activated via the PDO assignment.
PWMi mode
The output PDO
0x1602
activates the PWMi mode.

The output PDO
