Installation and hardware wiring configuration
2.1 FireWire Device Address Settings
Dial S1 to set the unique device number 1-32 for the driver, which corresponds one-to-one with the A3200 axis number; A single FireWire daisy chain can have up to 16 axes, while the entire machine can have up to 32 axes; The maximum length of copper cable is 4.5m, and fiber optic repeaters are used for long distances.
2.2 Power terminals
TB101 control power supply (85-240VAC): After the emergency stop cuts off the motor power supply, the power supply does not cut off, maintaining communication and feedback (keep alive function).
TB102 motor power supply: AC input, A/B/C three-phase motor power output; External delay fuse is required; Grounding must be protected.
Transformer selection: TV/TM series isolation transformer, capable of outputting 40/80/160/320VDC DC bus; TM3/TM5 transformer can supply power to up to 4 HPe units at most.
EXTSHUNT external discharge resistor TB103: The bus is automatically connected for discharge at approximately 380VDC; The manual provides a formula for calculating regenerative energy, which is used for selecting large inertia systems.
2.3 EMC/CE wiring mandatory requirements
Motor cables must be shielded, and the shielding layer must be grounded for protection; The D-SUB connector uses a metal shell for crimping and shielding.
Power cables and encoder/IO signal lines are physically separated and routed.
Mandatory installation of Aerotech UFM-ST power filter on AC input end; Install designated ferrite magnetic rings on motors and FireWire cables.
The driver is a component, and the final whole machine needs to undergo a complete EMC test.
2.4 Motor wiring and phase setting
Supports brushless, brushed DC, and two-phase stepper motors, with Aerotech’s original motors directly using matching cables; Third party motors must be phase modulated, and two sets of phase modulation methods are provided:
Live phase modulation: Motor Phasing Calculator tool for A3200 configuration manager, Nstat software to view Hall status.
Power off oscilloscope phase adjustment: measure the motor back electromotive force and Hall timing, and verify the phase alignment relationship.
Brushless motor: Hall HA/HB/HC connected to J207; Hall all 0s or all 1s are Hall faults.
Brushed DC motor: connected to A/C, with vacant B terminal; Measure the polarity of the back electromotive force of the manual motor to determine the direction of rotation.
Two phase stepper motor: connected to A-B C; The encoder must verify the phase.

2.7 TB201 ESTOP emergency stop input
Only used as a signal detection port, cannot cut off the motor power itself! 5-24V input; Only report faults; A truly safe shutdown requires an external relay to cut off the AC power supply to the TB102 motor, while keeping the TB101 control power supply powered on; Axis parameter FaultMask enables ESTOP fault; Add RC/varistor to the relay coil to absorb surges.
2.8 Two wiring schemes for holding brake
Use motherboard TB202 power supply+J207 solid-state relay output;
Use IO expansion board TB301 mechanical relay;
Two sets of brake relays are prohibited from being activated simultaneously, choose one from the other.
