I’m trying to power cycle the device connected to my UR5e robot tool. So I’d like to set Tool Output Voltage to 0, and back to 12 Volts. It seems that I can read the Tool Output Voltage using RTDE with “tool\_output\_voltage”, but it’s not clear if I can also set this using RTDE. I’d appreciate any help with this.
