Pulse width modulation with flexible ON period, optional current control and dither function (the dither function overlays the setpoint, if required, with an oscillation that keeps the valve in motion and thus allows precise control of the valve position).
Control of a DC motor with a PWM signal and direction reversal
ON and OFF delay; forwards the input signal to the output. The rising and falling edge can be delayed separately to the microsecond.
Frequency output with defined output frequency
Hardware functions
Switching frequencies to 10 kHz; at reduced output current to 0.1 A up to 100 kHz
Push/pull output driver for especially steep edges at the outputs
Polarity change in DC motor operation for direction reversal
Channel functions for flexible adaptation to the requirements of a machine and the respective sequence
HW enable; Start of signal output with the onboard digital input
Parameterizable ON delay; allows precise delay between the HW enable and the start of output Current measurement in the operating modes pulse-width modulation and pulse chain; enables control of the output current to the mean value over a period. Temperature influences can thus be balanced to the resistance of the actuator.
The respective main setpoint in each operating mode is controlled cyclically by the PLC, and other values can be modified flexibly from the user program.
Supported system functions
Isochronous mode enables precision-timed connection of the setpoint output to a higher-level controller
