Product Description:

Rexroth Indramat offers a unique spectrum of services for factory owners, helping them repair, maintain, and modernize heterogeneous machinery. Bosch Rexroth’s MHD Servo Motor is a permanent magnet servo motor equipped with an encoder for commutation. This MHD encoder feedback device is strategically designed by Indramat to provide advantages such as a quick start and continued reliability.

The AC Servo Motors of the MHD Series by Rexroth Indramat are mainly used as servo and main drive motors. In most cases, they are used to operate machine tools, printing and paper-processing machinery, packaging and food-processing applications, and factory automation. With the MHD Servo Drives, factory owners can easily automate their production and let the motor control units with different driving powers and interfaces do the work. Rexroth Indramat’s MHD servo motors are also able to operate in very harsh environments, due to their IP 65 degree of protection and categorized housing. These MHD motors can easily be mounted in any orientation, as the direction of their electrical connections can be adjusted to the requirement.

The MHD041A-144-PP0-UN synchronous motor by Rexroth Indramat is a popular choice amongst the series. With an 82mm Flange size, 50mm centering diameter and a frame length of 1.3 Nm, the MHD041A-144-PP0-UN motor is able to provide for a wide range of applications in the factory. The motor encoder on the MHD041A-144-PP0-UN motor is a digital servo feedback with an integrated multiturn absolute encoder. Rexroth Indramat’s MHD041A-144-PP0-UN motor also has a shaft with a keyway and comes without a holding brake. The MHD041A-144-PP0-UN can be shipped to any address globally with a one-year warranty period from Wake Industrial.

Fault/Error	What It Means	Corrective Action
Overtemperature Warning	Motor temperature has exceeded its threshold	Check ambient temperature, ensure proper ventilation, inspect cooling fan if present
Encoder Feedback Error	Incorrect or missing encoder signal	Inspect encoder cable and connectors; check for contamination or misalignment
Motor Does Not Start	Drive is not receiving or outputting correct signal	Confirm control wiring, check drive enable signals, test motor with known-good drive
High Vibration or Noise	Mechanical imbalance or bearing wear	Check for shaft misalignment, inspect bearings, and re-mount motor if necessary
Brake Not Releasing (if equipped)	Holding brake remains engaged	Check brake control voltage and wiring, inspect brake release circuit
Motor Shaft Locked	Internal mechanical jam or external obstruction	Inspect for seized bearings, remove any load from shaft, turn by hand (power off)
Low Torque Output	Insufficient current or drive settings misconfigured	Verify drive torque limits, motor parameters, and mechanical load
Positioning Inaccuracy	Faulty encoder or mechanical backlash	Inspect encoder, check for loose couplings or worn gearing
Motor Overcurrent	Excess load or short circuit condition	Reduce mechanical load, inspect motor and cable insulation for damage
Drive Displays Fault Code F226	Motor type mismatch or incorrect parameterization	Verify correct motor file loaded in drive, re-enter motor nameplate parameters
