I NTRODUCTION
ClearPath-EC motors in this family require a DC Bus Motor Power
Supply such as the Teknic IPC-5 (75VDC) described later in this section
and online here
. Note: Properly specified third-party power supplies may
also work with ClearPath-EC motors.
ClearPath-EC also supports the use of an optional Logic Power Backup
Supply for applications requiring uninterrupted Logic Power to keep the
motor's processor, communication, and position sensor circuits alive.
DC B US M OTOR P OWER S UPPLY (24-75VDC)
The DC Bus Motor Power Supply provides power to the ClearPath-EC’s
motor drive circuits. The Teknic IPC-5 (75VDC) is one example of a
ClearPath-compatible DC Bus Motor Power Supply.
L OGIC P OWER B ACKUP S UPPLY (12-75VDC)
Users can opt to use a Logic Power Backup Supply for applications that
require uninterrupted power to the motor's low power systems (processor,
communication, position sensor circuits, etc.).
Note: Teknic stocks a Logic Backup Power Supply that is 24VDC@6.5A.
For more information visit the Teknic webstore and search on part
number PWR-IO-24VDC, or click here
for a direct link.
The POWER4-HUB-S power distribution board requires a Logic Power
Backup Supply in addition to the main DC Bus Motor Power Supply.
Important: Logic Power alone cannot power the motor windings for
motion.

x Check for proper DC power polarity before connecting power
to a ClearPath. Reversing DC power polarity will permanently
damage the motor. Follow this link
for more information.
x Before connecting a power cable to a ClearPath-EC motor,
verify that the supply is turned off and discharged to prevent
electrical arcing from damaging the connectors.
x Note: When a ClearPath motor is powered up, a startup
routine energizes the motor for a few milliseconds. During
this startup routine a small amount of motion may occur at
the motor shaft (<1˚ typical).
On tightening M12 connectors. For a reliable seal, tighten the
communication and power cables between 0.8 Nm-1.4 Nm. Tip: When
M12 cable connectors are properly tightened there should be no more
than 1-2 threads visible on the motor connectors.
