Mitsubishi Okk HM-40 MDS-A-SP-300 drive
 |
The Mitsubishi Okk HM‑40 MDS‑A‑SP‑300 is a compact spindle drive used to control high‑speed motors in CNC or machining applications. Common failure modes for this unit include burnt or tripped protection relays on the power supply side, damaged PCB traces from overvoltage, and encoder misalignment or wear that causes loss of position feedback. Initial checks should verify the 48 V DC input voltage and isolation of the motor leads, inspect the drive’s PCB for burn marks or cracked components, and review any stored error codes (e.g., E‑codes related to overload or encoder fault).[oss-gpt-20b] |
