The TXM34Q-3RG StepSERVO integrated motor is a drive+motor unit, fusing a NEMA 34 step motor and a servo drive into a single device. Power to the drive, located at the rear of the motor, must be supplied by an external DC supply. See Related and Recommended Products below for compatible 24 and 48 volt DC power supplies.
StepSERVO technology combines the high torque capabilities of a step motor with the closed loop dynamic control of a servo system. The result is a highly customizable all-in-one motion control solution that operates quietly and efficiently, requiring only the minimum amount of current to maintain commanded position and velocity. Boost (or peak) torque that is higher than the rated holding torque increases the limits of acceleration, leading to faster cycle times. With software selectable servo loops that have been pre-tuned for various inertial loads, the TXM StepSERVO can be applied in systems where a traditional stepper would not be capable of achieving the high accuracy required.
The TXM34Q-3RG StepSERVO integrated motor can be operated in several different control modes, including streaming command mode using SCL commands or Modbus RTU, pulse & direction mode, velocity mode, and stored program mode which offers the ability to run a Q program stored in non-volatile memory. Q programs are created using Applied Motion’s Q Programmer™ software, which provides powerful commands for motion, I/O, conditional processing, multi-tasking, math functions, and more. All TXM34 integrated motors are set up, configured and tuned using Applied Motion’s Step-Servo Quick Tuner software with built in Q Programmer.
Each TXM34 integrated motor comes with 5 digital inputs, 3 digital outputs, and 1 analog input. The digital inputs accept signals of 5-24 VDC and can be used for connecting pulse & direction signals, end-of-travel limit switches, jog switches, quadrature encoder signals, PLC outputs, sensors, or many other signal types. The digital outputs can be connected to PLC inputs, counters, lights, relays, or other devices. The analog input accepts 0-5 VDC signals and can be used for velocity and position control. The TXM34Q-3RG comes with an RS-485 port for programming and serial communications to allow for the use of either Modbus RTU or Applied Motion’s Streaming Command Language (SCL). An integral 5000-line (20,000 count/rev) incremental encoder is housed inside the same enclosure as the drive electronics and used for closed-loop servo control to attain highly accurate position and velocity control. Encoder counts can be accessed over the network or from within the Q program using data registers. All TXM34 models are RoHS compliant and meet IP65 standards to ensure reliable operation in wet and dusty installation environments.
