Product Description

6MDDN-1P4101 is a 460 V, 50/60 Hz, 3-phase MD60 Drive that is manufactured by Reliance Electric. The output current is 1.4 A, the horsepower is 0.5 HP, and the output power is 0.37 kW. A is the frame size, and this particular drive does not have a filter. There are many protective features on the MD60 drive, including the bus overvoltage trip, the bus undervoltage trip, the software current limit, the hardware current limit, the instantaneous current limit, the power dip ride-through, and the fault-free ride through. Do not attempt to operate this drive unless you are qualified electrical personnel with knowledge of the equipment.

There are a number of fault codes that may appear on the drive. Fault code F70 is a power unit fault, which means that an error has been detected in the power section of the drive. This fault is not auto-resettable but can be corrected by cycling power or replacing the drive if it cannot be cleared. Fault code F81 is a communication loss fault, which means that port RS485 stopped communicating. Check the port wiring and the connection. A module may have been intentionally disconnected from the port. Fault code F100 is a parameter checksum fault, which means that the checksum read from the board does not match the checksum calculated. Reset the defaults on the drive to clear this fault, as it is not auto-resettable. Fault code F122 is an I/O board failure. To correct this fault, cycle the drive power. If the fault does not clear, replace the drive.
