Figure 3: Basic connections to the DFS-1 controlled POWERTEC Brushless DC motor control, using the factory default
settings for some of the inputs and outputs. Note that the speed pot input is the default, and that using the 4-20mA input
will require a change in the DFS-1 setup.
POWER CONNECTIONS:
POWERTEC Brushless DC motor controllers
are supplied with nominal input voltages of 230, 380,
and 460VAC. Three phase input power is required.
The input is not phase sensitive. Connect the appro-
priate power supply to the input fuses at L1, L2, and
L3 (check nameplate for proper input voltage and
capacity).
Connect the output terminals T1, T2, and T3 to
the respective terminals on the Brushless DC motor.
It is very important that the T1 terminal on the motor
connects to T1 on the drive, T2 of the motor connects
to T2 of the drive, and T3 of the motor connects to
T3 of the drive. An earth ground wire of the same
gauge as the motor power leads or one gauge smaller
(no smaller than #14 AWG) must be run from a bolt
1.0 CONNECTIONS
in the motor junction box to the ground terminal on
the drive. A wire must then be run from the ground
terminal on the drive (next to the motor terminals) to
an earth ground at or near the power source. The
Model 1000 drive does not have the common
circuitry connected to earth ground (chassis). In
most cases this works best, but in some cases it does
not. POWERTEC recommends connecting a short
jumper wire from the drive common at any one of the
several places available on the terminal strips to a
nearby point on the drive chassis or backpanel that
will establish this ground. This is more important in
applications where multiple drives are connected
together or serial communications from a host are
used. All other POWERTEC drives have the
common grounded by mounting screws on the
regulator boards.
