The internal encoder option is a 512-line (2048 count)differential magnetic encoder. The internal magnetic encoder offers two key advantages:
1. Reduced connections externally, thus reduced system cabling, as encoder feedback is all internal to the MDrive Plus.2. Smaller footprint to the MDrive Plus than an externally mounted encoder.
Remote encoder interface(1)
The remote encoder option, while adding additional wiring to the MDrive Plus, offers two key advantages:
1. The user chooses the type of encoder and line count.2. The encoder may be placed directly on the load rather than at the encoder shaft.
Note: The remote encoder interface reduces the number of available I/O points from 8 to 4. General purpose I/O 9-12 and Step and Direction I/O are replaced by differential encoder inputs.
Communication ConvertersElectrically Isolated, in-line converters pre-wired with mating connectors to conveniently set parameters and program a single MDrive Plus via a PC USB port.
Prototype Development Cables
Prototype development cables are designed to speed test/development with pre-wired mating connectors that have flying leads other end. No prototype development cables are available for the MDrive Plus using the 12' Flying Leads or Pluggable Clamp Terminal Strip.
If building your own cabling, you will need:
Mating Connector KitsMating Connector Kits are used to build your own cables. Kits contain 5 mating connector shells with pins. Cable not supplied. Manufacturer crimp tooling recommended.
The function of the DPM75 Drive Protection Module is to limit the surge current and voltage to a safe level when DC input power is switched on and off to a motor drive. This provides the added protection necessary for reliable motor drive operation when switching the DC power, instead of the recommended AC power to the DC power supply. The device is designed to protect the motor drive when operating under all load conditions. This device does not protect the motor drive from wiring the power incorrectly.
The unit is capable of being used with 48, 60, and 75 volt rated motor drives. An external jumper selection is available so the user can match the circuit to their particular application. The DPM75 is capable of a steady state operating current of 4 amps.
The DPM75 can be used for any frame size motor drive, when properly configured. It can also be used for more than one unit provided the current and voltage do not exceed the DPM75's ratings. The maximum DPM75 ratings are 75 volts and 4 amps.
