MD60 AC Drives

For applications from 0.25 to 5 HP, the MD60 is a simple AC Microdrive that can be panel mounted as well as wall or machine mounted.

Reliance Electric's MD60 AC Drive is ready to operate out-of-the-box! The drive includes a built-in LED display and operator controls, including a single turn potentiometer for speed reference. Built-in dynamic braking circuitry only requires the addition of a braking resistor to meet higher performance application needs to handle fast accel & decel rates.


AC Drives Analog DC Drives


This is the criteria that drove the development of the MD60 AC Drive. This product offering is targeted at the fastest changing and growing segment of the variable speed drive market - the market from fractional to five horsepower.


The MD60 is a Volts per Hertz controller which is suitable for general purpose use in a multitude of applications. Listed below are some of the Advanced Parameter functions which are useful when configuring the MD60.


For simple conveyors, mixers, agitators, and machine applications, the MD60 provides a cost effective solution. These applications will benefit from the 200% Over Current (for 3 seconds) capacity of the MD60 Microdrive. Some additional advanced parameter features include: · V/Hz Operation, Speed Regulation +/- 2% of motor base speed 40:1 Operating Speed Range · Start Boost (Voltage Boost) improves breakaway torque at the low end of the drive's frequency output. · S-Curve Acceleration may enhance performance and control of high inertia loads by tapering changes in speed rates during initial starts, as well as when approaching desired speed settings. · Dynamic Braking provides the ability to dissipate excessive DC Bus Voltage and thereby avoid High Bus Fault conditions normally experienced during extremely fast acceleration rates as well as in fast deceleration rates where the inertia of the load attempts to overhaul the electric motor.

Digital DC Drives


The parameters of the MD60 are segregated into groups, PParameters which reflect the basic values required for operation, and A-Parameters which are associated with more advanced use. This simplifies setup and minimizes customer exposure to unwanted parameters during startup. During use, the operator can monitor as many as 19 D-Parameters to display values such as Output Frequency, Output Current, Output Voltage, as well as the status of specific I/O points and the firmware version level. Fault conditions are identified by alpha-numeric codes such as F2. Each MD60 AC Drive has a label adhered to its left side providing a description of the Fault Codes, as well as the most common Display and Basic Configuration Parameters to help in setup and during use. Centrifugal fans and pumps are well suited for the MD60 which will provide good speed control beyond the 10:1 speed range normally required by these applications (i.e. 180 to 1800 RPM). Some the advanced parameter functions that can be considered during setup and operation include: · Output Carrier Frequency selection which is adjustable from 2 to 16 kHz, to achieve low acoustic motor operation. · Reverse Disable since fans and pumps are uni-directional and can become damaged if inadvertently operated in reverse. · Auto-Restart with up to 9 attempts, along with a settable delay time between attempts, since many variable torque applications operate un-manned in remote areas. Also, with 2 Analog Inputs standard, an isolated 0-10 VDC and a 4-20 mA input, the MD60 can be easily used in any automated process control system.
