The UMI-7764 to AKD Drive Cable contains the following connections:
• UMI-7764 Screw Terminal Leads —Pigtail wire leads labeled with UMI-7764 signal
names.
• X8 10-Pin Connector —10-pin connector containing the servo command, enable, and
fault signals.
• X9 DSUB Connector —9-pin DSUB connector containing emulated encoder output
signals from the AKD servo drive.
• X1 3-pin Connector —+24 V power supply connection for the AKD servo drive.
• +24V Power Supply Leads —+24 V power supply leads.
3. Configure the UMI-7764 DIP switches. You must set the DIP switches to the following
settings to match the polarity configuration for the AKD servo drive:
• Inhibit Input (S2)—Active High
• Inhibit Output (S1)—Active Low
The UMI-7764 DIP switch configuration is shown in Figure 7.

4. Connect an ex5 V power supply to the UMI-7764 Power Input Terminal Block. This
connection is required to power the encoder circuitry that converts differential encoder
signals to single-ended signals for the motion controller, as well as to power the UMI-7764
Inhibit Output signals.
