Stepping motor control has pulse width
modulation
Automation terminal block offers the chance of a pulse width modulation of the output signals. It also has two independently working channels.
With the automation terminal block IB IL PWM/2 in the Inline system of Phoenix Contact you now have the chance of a pulse width modulation (PWM) of the output signals It has two independently working channels

Sensor connectors withstand vibration
In addition to the large range of distribution boxes Phoenix Contact is now offering all the versatility of the M8 and M12 sensor connectors in a new design.
Both output signals are available in 5V and in 24V.
Depending on the operation type the high-phase of the period, the duration of the period or the frequency are adjustable.
In this process the operation types PWM, frequency output, single shot as well as pulse/direction signal output are supported.
The pulse width modulation for example is used with the control of heating elements.
The period duration can be adjusted between 100 microsec and 10 sec.
The starting phase is parameterized with 8 Bit solution.
The frequency output is similar to the operation type PWM, with the only difference that a frequency between 0 and 50kHz is specified.
With single shot an impulse is put out that can be adjusted between 10 microsec and 25,5 sec.
This impulse signal is for example used to control a valve in a filling process.
The volume to be filled then is proportionate to the impulse duration.
In the operation type pulse/direction signal output the terminal controls the step motors.
In this process the impulse frequency can be changed continuously between 0 and 25 kHz.
The generated impulses are counted by the terminal in a position counter depending on the direction signal upward or downward.
Furthermore a target position can be entered, which causes the impulse output to stop automatically when it has been reached.
