ACvoltages up to 500 Vac canbe connected dependingonrequired voltageEnhanced Converter TechnologyTMdrive-P70 VAR ControlThe TMdrive-P70 converter can be configured in two modes, providingVAR Control within the limits of its current capacity.One mode is the conventional PWM type normally set to holdunity power factor for all load conditions. (Shown in red)Another mode is the Fixed Pattern type, providing voltage stability,improved harmonics and efficiency. The Fixed Pattern mode stabilizesline voltage by providing system VARs when line voltage is low anddrawing VARs from the system when the voltage is high. By convention,VARs from the system are (+) and cause the line voltage to drop whileVARs from the converter are (-) and cause the line voltage to rise. Therelationship of line voltage, loads MW and converter MVAR is shown bythe blue voltage lines depending on the measured line voltage.MVA vs. MW and Voltage11

Application ExamplesApplying the TMdrive-70 Starts With the Motor DesignConsideration must be given to motor design when applying the TMdrive-70. A primary constraint is the motor terminal voltage. It isimportant that the motor terminal voltage does not exceed 3400Vac under any operating condition. Reserving voltage margin correctlyis critical to success. Detailed motor design data is needed for correct application.OL_VOverload derate. The rated motor voltage over theterminal voltage of the motor at maximum appliedoverload. Motors with no overload use 1.0.ST_VField forcing margin needed when applyingsynchronous motors. Apply 0.94 for synchronous motorsystems.RP_VReduction in maximum voltage due to the dc bus rippleof the drive at low frequencies. If the base frequency isbelow 5 Hz then this derate is 0.97, otherwise it is 1.0.SP_VSpeed margin. For motors that run above base speedthis is the ratio of the terminal voltage at base speedover the terminal voltage at top speed under maximumoverload at each point. Other motors use 1.0.Maximum Rated Motor Voltage = 3400 x OL_V x RP_V x ST_V x SP_VExperience has shown that the following maximum rated motor voltages apply based on the type of motorand the application.InductionSynchronousRated MotorOverloadExample(Maximum Voltage at max OLMaximum Rated Motor Volts FrequencyRequirementApplicationand top speed)3400 3300 60 Hz 100% Pump or Fan3300 3200 30 Hz 200% Mine Hoist3200 3100 5 Hz 225% Mill StandTMdrive-70 Notes1. Power bridge cabinets are 1650 mm (65in) in depth.Control cabinets are 700 mm (28 in) in depth. Dimensionsdo not include required 50 mm (2 in) channel base.2. Allocate a minimum of 550 mm (20 in) above cabinet forfan maintenance.3. Power rating data assumes ambient temperature of0-40 ˚C (32-104 ˚F), altitude up to 1000 m (3280 ft) abovesea level.4. The specified current ratings are continuous to which theindicated overload may be applied for a maximum of 60seconds.5. Each cabinet requires 3-phase control power.6. For high performance torque regulation, a temperaturesensor is mounted in the motor.7. All TMdrive-70 cabinets require 1000 mm (40 in) backaccess for connections and maintenance.8. Speed and current regulator responses are computedper the adjacent figure in radians/s. Speed regulatorresponses shown are maximum available. Actual responsewill be limited by drive train mechanical conditions.Accuracy and linearity specifications shown are asmeasured under controlled conditions in our lab and whiletypical may not be achievable in all systems.129. Water connections for separatetype cooling systems are locatednear the floor in the rear of powerconverter cabinets. The flange is1500 mm JIS-10K50A. Stainlesspiping is required for plumbing ofthe de-ionized loop.10. dc Bus bar included in lineups israted for one inverter only. Forcommon bus systems, convertersStep ResponseResponse at 95%of final valueand inverters are arranged so that this limitationis not exceeded.11. When output or input reactors are used to parallel systemsthen the dc Buses of those systems must be connectedtogether.12. Systems that share a common dc Bus must have thesame winding configuration for their converter transformersecondaries.13. Field supply enclosures are typically installed directlybehind control enclosures within the lineup.14. TMdrive-D70 converters require a minimum of 10% totalinput impedance. TMdrive-P70 converters require aminimum of 15% total input impedance.15. Systems with a base frequency below 5 Hz mayrequire additional 800 mm (32 in) capacitor panelsfor each dc link.1T 95%includesresponse latencyTimeT 95%Response = 3/T95% (radians/s)
