Product Description:

The MSK050B-0600-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit is intended for closed-loop motion axes in packaging lines, pick-and-place gantries, and other automated stations where precise torque and speed regulation are critical. It delivers regulated mechanical output through an internal permanent-magnet rotor, while its standard-profile housing helps it fit into compact multi-axis machine layouts.

Thermal management relies on natural convection, so heat dissipates through the aluminum frame without external blowers or liquid circuits. Position feedback is handled by an optical encoder with a connector that is rotatable through 240°, which helps with cable routing in crowded machine spaces. Electrical communication between the encoder and the drive controller follows the Hiperface protocol, allowing position data and electronic motor data to travel over the same interface. Within the feedback device, the scanning head resolves rotor position into 128 signal periods per mechanical revolution, and the drive interpolates that signal for finer control resolution. The sensing method is optical, so position accuracy is not affected by nearby magnetic stray fields from adjacent equipment or high-current conductors.

An internal turn counter stores position across multiple revolutions and is identified as multiturn absolute, which allows the axis to retain position information after power loss. Torque is transmitted through a plain shaft without a keyway, making it suitable for backlash-free clamp couplings. The motor uses winding code 0600, which matches its electrical characteristics to compatible IndraDrive controllers. Its frame code is 050, and the unit is supplied without a holding brake, so any vertical load must be secured by an external mechanism when power is removed. The motor is built in the standard design class and uses the B-length housing for this frame size.

Fault / Drive Error

What it usually means

Corrective action

 

Drive stays “bb” (not-ready) on H1

24 V *RF* (Drive-Enable) or mains still missing – controller only ready-for-power-up

Restore +24 V at RF input, check fuses / supply, then issue a Class-1 reset to reach “Ab” (ready-for-enable)

F207

Switching to an un-initialised operating mode (one of S-0-0032…35 = 0)

Reload valid mode parameters and acknowledge with S1 or software reset 

F208

Motor-type change detected – drive data ≠ motor ID tag

Upload the correct **MSK050B-0600** file, run *Basic-Load* and power-cycle

F212

Encoder signals out of range – sine/cosine amplitude too low / noisy

Check shielding, reseat feedback plug, route signal cable > 100 mm from power cable, replace encoder if needed

F218

Amplifier heat-sink over-temperature – drive shut down

Clean filters, verify fan, improve cabinet airflow, let drive cool before reset

F219

Motor over-temperature shutdown (thermistor > ~155 °C)

Reduce load, allow full cooldown, inspect motor-temp wiring 

F220

Bleeder-resistor over-temperature – regenerative overload

Lengthen decel ramp or add / up-rate external brake resistor

F226

DC-link undervoltage while enabled – mains sag / weak capacitors

Check three-phase feed and DC-bus caps, tighten power wiring, look for blown fuses

F229

Encoder-1 failure – quadrant error (signal sequence wrong)

Inspect/replace encoder cable, keep feedback leads clear of EMI sources

F230

Max. encoder-1 signal frequency exceeded – axis velocity too high

Review gearing & speed limits; if required fit higher-speed encoder

F234

E-Stop activated – +24 V removed at safety input

Trace safety chain, clear E-Stop cause, restore +24 V and reset
