Chapter 2 Getting Started CDS-3310
Peak Current Operation
Step 7a. Connect Brush Servo Motor
The CDS-3310 allows for brush operation. To configure an axis for brush-type operation, disconnect
power and connect the two motor leads to Phase A and Phase B connections on J1 MOTOR and leave
Phase C disconnected.

J1 MOTOR (4-pin)
AMP# 172167-1 AMP# 170361-1
Set the controller into brush-axis operation by issuing BR n,n,n,n. By setting n=1, the controller will
operate in brushed mode on that axis. For example, BR0,1,0,0 sets the Y-axis as brush-type, all others
as brushless. If an axis is set to brush-type, the amplifier has no need for the Hall inputs. These inputs
can subsequently be used as general-use inputs and queried with the QH command.
Step 7b. Connect Brushless Servo Motor
Step A.
Connect Hall Sensors
To configure an axis for brushless motor operation, connect the Hall sensors to pins HALA,
HALB, and HALC on 15-pin high-density connector J2 ENCODER. The CDS-3310 can only
be connected to a brushless motor with 120 degree Hall commutation. Verify that the hall
sensors change state with the QH command.
Step B.
Connect Motor Leads
Next, disconnect power and connect the three motor power leads to the phase A, B, and C
connections on the J1 MOTOR connector.

Step C1.
Test wiring manually
The motor wiring must correspond to the Hall wiring, so if the motor manufacturer indicates
how to do this, simply connect the power leads as specified. Otherwise, you will need to try
up to six motor power lead combinations (keeping the hall sensor wiring fixed) until smooth
motion results. Three of the combinations result in a stall condition (no torque), two result in
