The Safe Disable circuit has two isolated channels (terminals H1 and H2) that stop the output transistors. The input can use the internal power supply of the drive.
Set the EDM function to one of the MFDO terminals [H2-xx = 21 or 121] to monitor the status of the Safe Disable function. This is the “Safe Disable monitor output function”.
