of Blower Operation Characteristics] [Ratio of Motor Power Consumption during Acc./Dec.] •Achieved a higher level of energy savings during acc./dec. to say nothing of during constant speed. FR-F700 Conventional model(FR-F500) Motor Lord Torque (%) (1) Upgrade of the renown Optimum Excitation Control!! •The effect of energy savings can be confirmed using the operation panel, output terminal (FM, AM terminal) and via networks with the newly developed energy saving monitor. (2) The effect of energy savings is obvious Ex. of Power Savings Monitor Display [Energy Saving Monitor List] Power saving monitor (kW) Power saving rate (%) Power saving amount (kWh) Power saving amount charge ($) Power saving average value (kW) Power saving rate average value (%) Power saving charge average value ($) Annual power saving amount (kWh) Annual power saving amount charge ($) 0 10 20 30 40 50 100 90 MORE SAVINGS! Driving of the Mitsubishi 400V 4 poles 45kW motors comparison 12% Commercial power operation Frequency (Hz) V/F control 0 10 20 30 40 50 60 20 40 60 80 100 Optimum excitation control 6% Power Consumption (%) Power Consumption Ratio (%) A Photo:FR-F740-5.5K RS-485 terminal Combed shaped wiring cover Removable terminal block Easy operation with the setting dial of the operation panel Built-in EMC filter AU/PTC switchover switch Connector with/without EMC filter RS-485 communication is possible with PU connector Easy replacement with the cooling fan cassette!! E G C H A B D F BEST MATCH •Possible to set the torque pattern that is optimum for the machine's characteristic •Possible to expect even more energy savings with optimum excitation control and optimum V/F pattern working together 0 V/F5 V/F4 V/F3 V/F2 V/F1 Voltage Base Frequency V/F Characteristic Torque characteristic curves V/F pattern Frequency Base Frequency Voltage (2) Enhanced PID function •Energy savings in low speed region ... PID shutoff (sleep control) function •Shorter PID startup time ... PID automatic switchover function •Monitor of set point/measured value/deviation possible ... PID monitor •Convenient for HVAC usage ... forward/reverse operation switchover is simple with an external signal •Corresponds to a wide range of detectors ... set point and measured value for PID input can either be voltage (0 to 5V/0 to 10 V) or current (4 to 20mA) (3) Adoption of the original operation continuation at instantaneous power failure function •Operation continues without the motor coasting when an instantaneous power failure occurred in fan and blower applications. *The inverter may trip and the motor may coast depending on the load condition. IPF Input Power Supply Output Frequency Deceleration Reacceleration When power is restored during deceleration •Restart can be made without stopping the motor when the motor is coasting due to an instantaneous power failure. (4) Restart after instantaneous power failure function •Smoothly restarts a motor that is rotating even in the opposite direction due to the windmill effect. (5) Flying start •Possible to avoid regeneration overvoltage alarm by automatically increasing the frequency and continue operation if the fan happens to rotate faster due to the effect of another fan in the same duct. (6) Regeneration avoidance function •Switchover to commercial power-supply operation is simple using R1 and S1 terminals of the control circuit and commercial power-supply switchover sequence. (8) Commercial power-supply switchover sequence •Protection of the motor can be certain since the built-in PTC of the motor can be input directly in addition to the electronic thermal relay function. PTC thermistor input…Positive Temperature Coefficient Thermistor (7) PTC thermistor input •Adoption of newly developed long life cooling fan (design life of 10 years*1) B Longer operating life is further enhanced with the use of ON/OFF control of cooling fan. •Adoption of long life capacitor (design life of 10 years*1, 2) A capacitor with specification of 5000 hours at 105°C ambient temperature is adapted. *1 Ambient temperature: yearly average 40°C (free from corrosive gas, flammable gas, oil mist, dust and dirt) Since the design life is a calculated value, it is not a guaranteed value. *2 Output current: 80% of the rated current of Mitsubishi standard 4P motor (1) Operating life of parts are further lengthened •Degrees of deterioration of main circuit capacitor, control circuit capacitor or inrush current limit circuit can be diagnosed by monitor. •Trouble can be avoided with the self-diagnostic alarms* that is output when the life span is near. *Any of alarm for main circuit capacitor, control circuit capacitor, inrush current limit circuit and cooling fan can be output. (2) State of the art longevity diagnostic method •Maintenance timer output function can also inform of maintenance time for peripheral equipments. •Average output current value and maintenance timer value are output as pulses.
