Talon FX
The Talon FX is built upon years of development in motor controller technology from Cross the Road
Electronics. The Talon FX is the next evolution of the Talon family of motor controllers, which continues to be
a leader in FRC motor controller technology.
Reverse Polarity Protection
The single largest cause of failure in FRC motor controllers is reversing the polarity of the input power. This
means a simple wiring mistake like wiring a motor controller backwards into the PDP (Power Distribution
Power) or wiring a robot battery backwards can be a costly mistake for a team. The Falcon 500 is the first
motor controller in FRC history to have reverse polarity protection built in. This means that if you do plug the
Falcon 500 in backwards, the Talon FX isn't damaged or destroyed.
Field Oriented Control (FOC)
The Talon FX is also capable of commutating the Falcon 500 using Field Oriented Control (FOC). This is
different from trapezoidal commutation, which only energizes 2 of the motor's 3 phases at any given
moment. With FOC, the Talon FX uses sinusoidal commutation to constantly energize all three phases.
Phoenix API Compatible
The Talon FX is a Phoenix compatible device. This means that teams can program the Talon FX using their
existing Phoenix-based code with only minor changes needed.
The Talon FX gives teams all the features they've come to
expect from a Talon motor controller, including Follow
Mode, limit switch feedback, and on-board motion control
using Motion Magic.
One new feature added to the Talon FX is that a 2048
CPR Encoder is now built in. This means that when you
buy a Falcon 500 you're not just buying a motor and
motor controller. You're also buying a high-resolution
encoder. For the first time in FRC history, a single
product is giving teams access to world championship
caliber motion control – out of the box, with no additional
hardware needed.
Another change from the Talon SRX is that the Talon FX
doesn't have a Talon data port and can't have an encoder
plugged into it directly. However, teams can use a CAN-
based encoder such as the Cross the Road Electronics
CANCODER (P/N 19-676768) as an input sensor for
Motion Magic.
