TQ10X User Guide
With the buses connected in parallel, the regenerated power from one TQ10X is
dissipated by the power consumption of the other.
In standard multi-axis applications, where regeneration occurs when one axis
decelerates, the energy can be used by other axes if the power bus is shared. This
improves system efficiency by using energy that would otherwise be wasted.
Connecting Motors from Other Vendors
Before connecting a motor from another vendor, you must determine which motor
phase wires correspond to Phase A, Phase B, and Phase C inputs on the TQ10X.
Similarly, you must determine which Hall effect wires correspond to Hall 1, Hall 2,
and Hall 3.
Connect each wire to its appropriate terminal on the TQ10X. Ensure that the Hall
effect sensors accurately transmit information about rotor position, and that motor
current is commutated to the correct motor phases. See the Appendix at the end of
this user guide for more information about using a motor from a vendor other than
Compumotor.
Connecting a Brushed DC Servo Motor
You can use the TQ10X as a drive for brushed DC servo motors. To do this, follow
these steps:
➀
Connect drive terminals
HALL 1
and
HALL 2
to
HALL GND
➁
Make no connections to drive terminal
HALL 3
➂
Connect the drive’s
PHASE A
to your motor’s positive input.
➃
Connect the drive’s
PHASE C
to your motor’s negative input.
Under these conditions (
HALL 1
and
HALL 2
connected to ground;
HALL 3
uncon-
nected), the drive’s internal logic determines that a brushed motor is connected.
The drive will send DC current out of Phase A, through the motor, and back into
the drive through Phase C. The amount and polarity of the current will be deter-
mined by the command input signal.
Shielded Motor Cables
Keep electrical noise from interfering with the signals that the Hall effect sensors
send to the drive. Position the motor as close as possible to the drive. If you need to
connect a long cable between the drive and motor, we recommend you use a
shielded cable for the Hall wires (Hall 1, Hall 2, Hall 3, +5V, Hall Gnd). Run the
power wires (phase A, B, and C) separately from the Hall wires.
Motor Grounding
For safety reasons, the motor case should be grounded. Often, the motor can be
grounded through the equipment to which it is mounted. This requires a good
electrical connection between the motor’s mounting flange and the equipment, and
that the equipment be connected to ground. Check with the National Electrical
Code (NEC) and your local electrical code to ensure you use proper grounding
methods.
Proper grounding can also reduce electrical noise.
GROUND THE MOTOR CASE!
The motor case must be grounded, to reduce electrical noise. An ungrounded motor can
cause electrical noise problems throughout the system, particularly in encoder wiring and
circuitry. This noise may cause the encoder to output erroneous information, such as
missing encoder pulses. To avoid electrical noise problems, ground the motor case.
