Hi everyone, I'm new in using this forum and on working with the galvos, I'm doing a project where I'm using the compact 506 with the microamp driver. In attachment there is the datasheet that medialas provided me for the drivers, with both the pinout for the output and input of the drivers. I modified the driver as specified on the galvos page and I'm using two power source, which can generate +-30V, from medialas, to source the two driver boards. I connected the +-30V and ground on the boards and as a test, before I connected the galvos to the driver board, I measured the voltage drop between the motor+ and motor- output of the driver board, so the input pin of the galvos. I measured a value of 30V, without any input. Even if I try to connect an input differential signal to the driver board the voltage drop between the two output pins remain 30V. So even if they are differential signals, isn't it too much 30V between the input pins of the galvos? How do the galvos work? Do they need always a voltage even if they are at the position 0?
