Introduction
Aerotech’s Ndrive MP (Ultra-Compact "Micro" PWM)network digital drive is a high-performance amplifier.
The drive provides deterministic behavior, auto-identification, and easy software setup.   The Ndrive MP’s
high-performance double-precision floating-point DSP controls the digital PID andcurrent loops.   All system
configuration is done using software-settable parameters, including control loop gains and system safety
functions.
TheNdriveMP is offeredwithanoptional encoderinterpolationfeature(-MXU), anauxiliary squarewave
encoder input for dual loop control, dedicated analog and digital I/O (expandable with the-IO option), and
separate powerconnections formotorandcontrol supply voltages
Power Dissipation
The first figure below shows theamplifierpowerdissipation undercontinuous powersupply andoutput
current conditions.  The values onthegraphrepresent thepeak current that the amplifier would provide during
operation.  Whenthebus voltageandoutput current are known, theamplifierpowerdissipationis foundusing
this graph.  Thesecondfigureshows themaximum recommendedambient temperatureas afunctionof
amplifier power dissipation.  Use this graph along with the power dissipation obtained from the first graph to
determine the maximum ambient temperature.  If the result is lower than the known operating ambient
temperature, additional measures are required to cool the NdriveMP.  Mountingit toalargemetal platefor
extra heat-sinking and providing additional fan flow are suggested
