TOSHIBA H7 Low Voltage 208/230 3HPStandard Duty Industrial The H7 Adjustable Speed Drive is ready for continuous, trouble-free operation in demanding manufacturing environments. It features open or closed loop true torque control, which is Toshiba’s vector algorithm that enables motors to develop high starting torque compensation for motor slip. A graphics capable, back-lit LCD display, RS485/RS232 ports and a programming/speed control encoder round off this advanced drive. The H7 is suitable for a variety of applications that require unparalleled motor control, rugged reliability and a user-friend operator interface H7 ASD Standard Specifications Adjustable between 0.5 - 15 kHz (ASD Specific, Consult Factory) Sine Wave PWM System- Flux Field Current Vector Control Open Loop Vector, Closed Loop Vector, Constant Torque, Variable Torque, Auto Torque Boost, Manual Torque Boost, 5-point V/f custom curve setting 100% continuous or 120% for one minute Rotary Encoder integrated into the EOI, 0 - 10 V, ±10 V, 4 - 20 mA, Binary Input, Motorized Potentiometer Input Analog Input ±0.2% of the maximum output frequency, Digital Input ±0.01% of the maximum output frequency 0.01 Hz Operation Panel, 0.1 Hz Analog Input. 10 to 12-bit A-D Converter Closed Loop (0.01%, 1000:1 speed range), Open Loop (up to 0.1%, 60:1 speed range) Closed Loop (5%, ripple < 2%, ±100 range), Open Loop (10%, ripple < 3%, 50% to 100% range) Eight Discrete Input Terminals programmable to 68 functions. The number of terminals may be increased using optional hardware. One 4 - 20 mA, one ±10 V and two 0 - 10 V (one of which is commonly used with a potentiometer) Three Discrete Output Contacts programmable to 60 functions Two 4 - 20 mA / 0 - 1 mA outputs programmable to 33 functions Optimal Three-Channel Signal Isolation for 4 - 20 mA input and the AM and FM outputs rated at 750 V Control Board Communications Ports RS232/485 and TTL Ports standard Input (L1, L2, L3), Output (T1, T2, T3), DCL (PO, PA), DBR (PA, PB), DC BUS (PA, PC) DC Bus Control-Power allows control power ride-through during momentary power loss (Except 600 V 100 HP and larger) ASD can clear fault upon trip automatically. Programmable to 10 times with wait time up to 10 seconds between retries ASD will catch a freewheeling motor smoothly. Temperature: -10 to + 40°C, 14 to 104°F, Humidity: 95% non-condensing Electronic Operator Interface (EOI) LCD EOI (Liquid Crystal Display/ Electronic Operator Interface) 240 x 64 graphics capable, back-lit LCD can display multiple parameters simultaneously. Keypad may be operated from an external power source. Software is flash upgradeable. Run (Red) / Stop (Green), Local / Remote (Green), DC Bus Charge Indication (Red) Local / Remote, Monitor / Program, Run, Enter, ESC, Stop / Reset, Up, Down Encoder with integrated Enter Key for Frequency and Parameter adjustments Completely configurable along with Scaling Factor Multiplier, Current Display selectable between Amps or %. Voltage Display selectable between Volts or % RS232/485 and TTL Ports standard Remote mountable up to 1000' away from the ASD (please look at our rules and privacy policy) |
