R911321350
The R911321350 (KSM01.2B-061C-61N-S1-HG2-SE-NN-D7-NN-FW), a distributed servo drive from Bosch Rexroth Indramat's KSM series, features a tricolor H1 LED indicator showcasing operational status. The LED remains off during hardware defects, incorrect cable connections, or when the power is switched off. First commissioning involves connecting the unit to a computer through its serial interface. It includes an integrated oscilloscope function and requires a pause of thirty minutes post-switch-off to allow for the discharge of DC bus capacitors. The unit accepts a winding code of 061 and depends on natural convection for cooling. It functions optimally within a 0-40°C ambient temperature range.
Equipped with a single-turn Hiperface optical encoder with 128 increments, handling the shaft-end needs careful attention to avoid damaging the encoder. This unit necessitates a minimum distance of 100mm between the motor power and motor encoder cables for interference avoidance. A copper wire with a minimum cross-section of 8AWG or 10mm2 is necessary for the equipment grounding connection. Lastly, the drive may initiate hazardous movements during operation in the event of a motor fault.
