Internal Product Review
The NY4140 is a single-axis linear drive featuring 8 digital inputs and 2 digital outputs. Motion integration feels especially well engineered thanks to 3 RS422 encoder inputs and 1 12-bit analog input. High-demand applications benefit from input current up to 6 Arms with forced cooling, making this unit an excellent choice for responsive single-axis control.

Product Description:
The NY4140 linear drive module is produced by Bosch Rexroth Indramat within the NY Linear Drives series. It is a single-axis motion controller intended for decentralized cabinets, supplying command, power, and feedback channels to a linear motor stage in automated machinery. By combining onboard processing with high-resolution feedback, the unit synchronizes carriage position and velocity so that pick-and-place, packaging, or material-handling stations can track programmed trajectories with repeatable accuracy. Compact mechanical dimensions make it suitable for multi-drive racks where panel space is limited.
Inside the 21.7 mm wide, 128.4 mm high, and 148.5 mm deep housing, the drive controls 1 axis through dedicated signal groups. Standard field wiring connects to 8 digital inputs for limit switches or sensors, while 2 digital outputs return drive-ready and fault states to the PLC. For continuous-value acquisition, the board carries 1 analog input with 12-bit resolution that can monitor a load cell or external process variable. Servo feedback is handled by 3 RS-422 encoder inputs, enabling primary and auxiliary position channels plus a probe line for capture events. These interfaces are complemented by two fast digital inputs and two fast digital outputs reserved for sub-microsecond trigger tasks.
The power section tolerates an intermediate circuit up to DC 170 V absolute maximum voltage, giving margin for regenerated energy during deceleration. Under natural convection, the device permits 2.5 Arms with convection cooling, which supports light to moderate thrust demands. Forced-air operation increases the permissible current to 6 Arms with forced-air cooling for applications that need higher continuous force. The control electronics consume only 4.4 W of logic power, so thermal load from the low-voltage side is minimal. Two 16-bit analog outputs are available for valve positioning or diagnostic scope functions, and the 5-volt domain supplies three recessed logic inputs for auxiliary tasks. Mounting clips engage a grounded backplane to maintain EMC compliance without adding bulk.
