4.3

Normal operation/Valve control

Normal operation

"Normal operation" refers to the function of the DQ 4×24VDC/2A HS as digital output

module.
Valve control is a special function of normal operation.

Valve control function

You use valve control to switch to a smaller "holding current" after tightening the valve

(locked-rotor current). You do this by activating a pulse width modulation (see section Pulse

width modulation (Page 19)).

With a 0 → 1 transition of the digital channel, the configured holding time is started. After it

has expired, the pulse/pause duty factor is activated as pulse width modulation. The

actuating signal is output digitally as a pulse sequence of on and off pulses.

Configuration

You configure valve control with the following parameters:

●

"Normal operation" operating mode

●

Holding time valve control

●

Pulse width modulation duty factor

●

Pulse width modulation time period

Chronological sequence

The figure below shows the chronological sequence for valve control. The pulse width

modulation is activated in the next possible data cycle.
