Pulse width modulation (with flexible ON period, optional current control and dither function)
PWM signal for controlling a DC motor
On and OFF delay; rising and falling edge can be delayed separately to the microsecond
Frequency output with defined output frequency
Hardware:
2 24V channels, 2A output current can be switched in parallel to boost performance to 4A of output current
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
1 high-speed 24 V digital input per channel with parameterizable input delay from 4 µs
Channel functions:
HW enable; Start of signal output with the onboard digital input
Parameterizable ON delay; for precise deceleration 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 mean value over a period. Temperature influences can thus be balanced to the resistance of the actuator.
Cyclic control of the respective main setpoint from the PLC in every operating mode; 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
Firmware update
Identification data I&M
