We usually use it with our own servo amps, but it generates PWM waveforms up to a practical limit of about 50 KHz (0.5% steps at 50 KHZ, finer resolution as you slow it down). It is fully supported by EMC2 and HAL, and the frequency setting can be made in the HAL files. It is currently set up for sign-magnitude, but it would be a trivial adjustment to make it do synchronous-antiphase.
