Daikin MD5 - Drives Control Connection Terminals; Control Terminal Descriptions

WARNING
Relay coils generate noise spikes in response to steps in
applied power. To avoid drive damage from such spikes,
all AC relay coils mounted across drive inputs require R-C
snubbers, and all DC relay coils mounted across drive outputs
require diodes – see gure.
Analog Cables
Recommendations for analog signal runs:
• Use double shielded, twisted pair cable.
• Use one individually shielded pair for each signal.
• Do not use a common return for different analog signals.
Digital Cables
Recommendation for digital signal runs: A double shielded
cable is the best alternative, but single-shielded, twisted, multi-
pair cable is also usable.
Control Panel Cable
If the control panel is connected to the drive with a cable, use
only Category 5 Patch ethernet cable.

Control Terminal Descriptions
The following full-page diagram provides a general description
of the control terminals on the drive. For specic application
details, see the Application Macros on page 9.
NOTE: Terminals 3, 6, and 9 are at the same potential.
For safety reasons the fault relay signals a “fault”
when the MD5 is powered down.
