Product Description:

The NYM04.1-2PW-LMS-NY4120/10 is a PWM drive module produced by Bosch Rexroth Indramat within the NY Linear Drives series. Intended for two-axis linear stages, the module supplies and regulates current for LMS linear motors, enabling precise thrust generation along machine tracks in industrial automation. By integrating the power stage, feedback conditioning, and protective logic on one compact board, it serves as the active link between the motion controller and the linear motor coils. This layout supports compact installation in motion systems where separate amplifier, feedback, and protection hardware would otherwise require additional panel space.

The analog front end has an input bandwidth of 125 kHz, allowing high-speed position or force references to pass through the filters without noticeable phase lag. The inputs present an impedance of 10 kΩ // 10 pF, so standard motion controllers can drive them without excessive loading. Current shaping is handled by an onboard loop that reaches a peak of 14 A per axis, or 22 A combined, giving the drive headroom for rapid acceleration. Pulse-width modulation runs between 16–96 kHz, and all functions draw from a DC bus of 15–75 VDC with supervision for under-voltage, over-voltage, overcurrent, and temperature conditions. That combination supports responsive current control while helping maintain smooth force output at low speeds.

The integrated position controller governs 2 axes simultaneously, matching each channel to one LMS primary coil in the selected configuration. With 2 analog inputs available, each axis can receive a separate velocity or position command while the drive uses internal DACs to generate an adjustable 15–75 V output window for the motor windings. Continuous thermal loading is supported by a rated current of 7 A, which accommodates steady-state thrust in cutting, pick-and-place, or inspection platforms. Separate command channels help the module coordinate paired slides or transfer axes that move at different setpoints. Because the drive manages two LMS coils, one linear motor can be connected to each axis without additional amplifiers.
