Product Description:

The RAC 3.5-100-460-A00-W1-220 main spindle drive controller from Bosch Rexroth is used for the digital control of the manufacturer’s 1MB and 2AD series of motors with a continuous power of 10 to 30kW at the output shaft. This product has a series code of 3 and a design code of 1. It has a broad speed range and an internal position control loop. The device is capable of positioning the spindle independently and operate as a C-axis with high precision. The unit is cooled during operation using a mounted fan. The main spindle drive is fitted with a programming module at the bottom. The controller can be shipped to any destination of your preference.

The product is capable of acknowledging the position of the rotor with a very small resolution.  This device is intended to be installed inside a control cabinet. The housing of the unit incorporates the heatsink for both the fan and power electronics. Its X3 connector serves as the motor feedback interface. The controller has a rated supply voltage of 3 x 380 to 460V and a rated frequency of 50/60Hz. The product comes with a continuous current rating of 70A.  The device can operate without data restriction between a temperature range of 5°C and 45°C.

The drive controller can be put to use in humidity-endangered areas. The unit is manufactured according to DIN VDE 0160 specifications. There must be a minimum distance of 160mm above and below the controller inside the control cabinet. The lid of the product features air slits through which heat is emitted during operation. The internal as well as external power dissipation of the device is dependent on the workload. The heatsink and air shaft of the unit should always be clean so that there is no overheating. The RAC 3.5-100-460-A00-W1-220 drive controller is backed by a one-year warranty.

Fault / Error What it means Corrective action
F2-26 Undervoltage DC-link voltage dropped below set threshold while the drive was enabled. Check 3-phase mains for proper 400 / 460 V supply, inspect line fuses and contactors, then cycle power and re-enable the drive.
F2-18 Amplifier over-temperature IGBT heat-sink exceeded safe limit. Verify cabinet airflow, clean filters, confirm fan operation, and reduce load or duty cycle until temperatures stabilise.
F2-19 Motor over-temperature Thermistor/NTC in spindle motor signalled overheating. Allow motor to cool, inspect cooling fan or spindle blower, and check for excessive cutting load or inadequate lubrication.
F2-28 Excessive deviation Position / speed error beyond parameter S-159. Check servo tuning, inspect encoder cable integrity, and verify machine mechanics for binding or backlash.
F2-29 Motor-encoder quadrant error Illegal quadrature sequence detected on motor feedback. Inspect encoder connector X4, clean contacts, and replace damaged feedback cable or encoder.
F2-33 +24 V external supply error Auxiliary control-supply voltage missing or below 22 V. Measure the external 24 V feed, locate short circuits, and restore regulated supply.
F2-34 Emergency-stop active E-stop chain is open. Reset machine E-stop, verify contactor wiring, and test E-stop circuit for proper dropout delay.
F2-36 Position-feedback difference Mismatch between commanded and actual position beyond tolerance. Realign spindle reference, check belts/couplings, and recalibrate encoder alignment.
F2-42 External-encoder signal too small TTL/HTL feedback amplitude below minimum. Inspect shield grounding, replace encoder, or switch to differential line-driver feedback.
F2-48 Low battery voltage Parameter-memory lithium cell or battery pack discharged. Replace battery, reload parameters from backup, and run a reference cycle to clear alarm.

Error code Meaning
F2-18 Amplifier over-temperature: heat-sink temperature has exceeded the shutdown limit. 
F2-19 Motor over-temperature: spindle-motor NTC indicates excessive winding temperature. 
F2-26 Undervoltage in the power section: DC-link voltage too low or drive enabled without mains power. 
F2-28 Excessive deviation: position/velocity error beyond parameter S-159 tolerance. 
F2-29 Motor-encoder failure (quadrant error): illegal incremental-encoder sequence detected. 
F2-33 External +24 V supply error: auxiliary control-voltage missing or below threshold. 
F2-34 Emergency-stop active: +24 V signal at E-stop input removed. 
F2-36 Excessive position-feedback difference between dual encoder channels. 
F2-42 External encoder failure: signal amplitude too small. 
F2-48 Low battery voltage: backup battery for parameter memory below safe level.
