Product Description:

Bosch Rexroth is not a new name in the field of mechanical tools, robotics and automation – it carries a proud history of around two hundred years of hard work and diligence with its name. This clearly infers that parts assembled at Rexroth are not a mere result of daily work by the people who work at this company but in fact they are the fruit of their passion and an extension of a decades old legacy. The company has not kept itself limited to a certain area of machines; it simultaneously produces many important products for the industry. To name some of its products we can mention hydraulic machines, gear technology, assemblies and various kinds of electric motors.

MSK030B-0900-NN-M1-UG0-NNNN belongs to the family of IndraDyn S synchronous servomotors by Rexroth which finds its applications in numerous automation and control systems. IndraDyn S servomotors by Rexroth cover a wide range of power spectrum which allows the technical experts and engineers to pick the one that best suits their design requirements. To make MSK030B-0900-NN-M1-UG0-NNNN function properly it must be assembled according to instructions and specifications explained in the technical sheets. Moreover another important factor to keep in view is to maintain the specified environmental conditions such as temperature and moisture in the air that are very likely to affect the performance of this synchronous motor. Compared to the other members belonging to IndraDyn S family MSK030B variants are the ones with the lowest continuous, standstill and maximum torque values which makes them suitable for the situations where low torque values and high number of rotations per minute are required.

Fault Code	Rexroth Diagnostic Message	Typical Cause on an MSK030B Axis	Practical Troubleshooting Steps
F2019	Motor over-temperature shutdown	Continuous overload, blocked airflow, or ambient heat pushing the stator sensor above its limit	Let the motor cool, verify the blower/fan, check for mechanical binding, and reduce sustained torque demand.
F2021	Motor temperature monitor defective	NTC/PT100 sensor open-circuit, short-circuit, or damaged cable between motor and drive	Inspect the temperature-sensor pair on X1/X2, ohm-check the thermistor, repair or replace the cable or motor if readings stay out of range.
F2025	Drive not ready for control	Drive-enable (AF) set while the drive was still in “bb” (ready) instead of “Ab” (power enabled)	Sequence the PLC so AF is issued only after DC-bus comes up and parameter mode is exited; clear errors, then re-enable.
F2026	Undervoltage in power section	Mains drop-out, faulty supply module, or bus capacitor ageing causing the DC-bus to fall below P-0-0114 threshold	Measure incoming line, inspect supply fuses/ contactor, test DC-bus capacitors, add line-filter or braking resistor if needed.
F2031	Encoder 1 signal amplitude incorrect	Sin/Cos encoder amplitude too low/high due to loose connector, bent pins, or shield grounding fault	Reseat X4/X5 encoder plugs, check screen continuity, scope the feedback channels; if still bad, replace resolver/encoder.
F2174	Loss of motor encoder reference	Shock‐load, vibration, or cable strain caused the encoder’s reference to be lost	Re-reference the axis in IndraWorks, tighten strain-reliefs, and verify encoder battery (if absolute) or multiturn counter.
F2177	Modulo limitation error of motor encoder	Encoder count exceeded permitted modulo range (parameter mismatch or firmware error)	Confirm motor data block matches drive parameters, reload motor nameplate, update firmware if fixes are rejected.
F2860	Over-current in mains-side power section	Shorted motor leads, phase-to-earth fault, or defective IGBT in power stage	Megger the MSK cable, inspect for coolant/oil ingress, disconnect motor to see if fault clears—if not, send drive for repair.
F4005	Error during phase regression	Improper phase-switch timing when returning from communication phase	Check mains contactor logic, verify safe-torque-off timing, and ensure correct phase-sequence wiring. ManualsLib
F8060	Over-current in power section	Severe short in motor windings or inverter bridge, often shows just before F8000 collective error	Disconnect motor and retest; if fault remains, the drive’s power section is damaged—swap modules or send for bench repair.

Fault Code	What It Means
F2019	The stator sensor reports the windings are above the permissible limit and the drive disables power. ManualsLib
F2021	The NTC/PT100 in the motor (or its cable) is open- or short-circuited, so the drive can’t track winding temperature. ManualsLib
F2025	AF (drive-enable) was issued while the DC-bus wasn’t yet OK or the unit was still in parameter mode. Converting Systems Inc.
F2026	DC-bus has fallen below the threshold defined in P-0-0114—usually a mains sag or failing capacitors. Bosch Rexroth
F2031	Sin/Cos feedback level is out of tolerance due to a loose plug, shielding fault, or damaged encoder. Converting Systems Inc.
F2048	The absolute encoder’s back-up battery has dropped below 3.1 V, so multiturn position is no longer guaranteed. ManualsLib
F2174	After power-up the drive can’t find a valid reference mark—reference was lost or the encoder was replaced. Bosch Rexroth
F2177	Travel exceeded the modulo range (S-0-0103 / S-0-0278) or the encoder counts cannot be recalculated fast enough. Converting Systems Inc.
F2860	Current through the supply bridge is above the device peak rating—often a shorted motor cable or bus fault. Bosch Rexroth
F8060	Instantaneous inverter current exceeded limits, typically caused by a phase-to-ground fault or IGBT failure.
