Connection
This section covers the methods of connecting the driver, motor, power and controller, as
well as the connection examples and I/O interface.
Terminal blocks
Screw terminals are used.
Remove the insulation from the core, then insert the core into the terminal and tighten with
terminal screws.
Strip 0.24 to 0.31 in. (6 to 8 mm) of insulation.
Tighten the terminal screw at the specified tightening torque.
Connecting the motor
Connect the motor leads into the driver's motor terminal block (TB2).
The CFK513 model has a connector with motor leads. Use the supplied motor cable with
connector.
Note
If the noise generated from the motor leads becomes a problem, shield the motor leads
with electrically conductive tape, wire mesh or the like.
Connecting to the power supply
The input power-supply voltage is 24 VDC ±10%. Use a power supply capable of
supplying the power/current capacity as shown below.
DFC5103T, DFC5107T
Driver model
Connecting the power-supply wires into the driver's power-supply terminal blocks (TB1).
Note
• For the power-supply cable, use a cable with a diameter equivalent to AWG20 (0.5 mm
for the standard type (DFC5103T, DFC5107T, DFC5114T), and AWG20 to 18 (0.5 to
2
0.75 mm
) for the high-speed type (DFC5128T). Be sure to connect the power supply
using the correct polarity. If the power supply's polarity is reversed, the driver may be
damaged.
• Do not route the power-supply cables in the same conduits as other power-supply lines
and motor leads.
• Always wait at least 5 sec. after switching off the power before switching it back on
again or connecting/disconnecting the motor-lead connector.
