Can be used for speed potentiometer, 1k W to 10 k W Al2: Factory setting: 4 mA to 20 mA. Impedance = 242 W (reassignable, x-y range with graphic display keypad). Factory modification J10 allows 0 Vdc to 10 Vdc reference signal to Al2, Z = 30 k W Frequency resolution in analog reference 0.1 for 100 Hz (11 bits) Speed regulation V/f control: equal to the motor's rated slip SFVC: 10% of the motor's rate slip from 20% to 100% of nominal motor torque Efficiency 97% at full load typical Reference sample time 2 ms 0.5 ms Acceleration and deceleration ramps 0.1 s to 999.9 s (definition in 0.1 s increments) Drive controller protection Thermal protection of power converter Phase loss of AC mains Circuit breaker rated at 100 kAIC Conforming to ANSI/IEEE C62.41 Category A and B Motor protection Class 10 electronic overload protection Class 20 electromechanical overload protection with bypass (2) Graphic display keypad 8 lines, 240 pixels by 160 pixels. Supports display of bar charts. Save and download up to 4 configuration files. Display is rated up to 60 C (140 F) Maximum operating temperature with IP54 protection Temperature Storage for all enclosures: -13 F to +149 F (-25 C to +65 C). Operation: +14 F to +104 F (-10 C to 40 C). For 1 hp to 100 hp drives (208 V, 230 V & 460 V) operating between 40 C and 50 C, derate the current 2% per C above 40 C. For 125 hp to 500 hp (460 V) operating between 40 C and 50 C, derate the current 3.3% per C above 40 C Humidity 95% with no condensation or dripping water, conforming to IEC60068-2-78 Altitude 3,300 ft (1000 m) maximum without derating Derating of the current by 1% for each additional 330 ft (100 m) Enclosure Type 1: all controllers Type 1G: 125 hp to 500 hp VT @ 460 V only Type 12/12K: all except 125 hp to 500 hp VT @ 460 V Pollution degree Type 1, 1G: Pollution degree 2 per NEMA ICS-1 Annex A and IEC 60664-1 Type 12/12K: Pollution degree 3 per NEMA ICS-1 and IEC 60664-1 Operational test vibration Conforming to IEC 60721-3-3-3M3 amplitude 1.5 mm peak to peak from 3 Hz to 13 Hz 1 g from 13 Hz to 200 Hz Transit test to shock Conforming to National Safe Transit Association and International Safe Transit Association test for packages Operational shock 15 g, 11 ms Seismic qualification IBC, ASCE 7 ICC ES AC 156 shaker table acceptance protocol, ground and roof top applications with an importance factor of 1.5 Codes and standards UL listed per UL 508C under category NMMS (Power Conversion Equipment) Conforms to applicable NEMA ICS, NFPA, and IEC standards Manufactured under ISO 9001 standards Factory modification G10 provides Canadian cUL certification (1) On 1 hp to 100 hp VT controllers, above 4 kHz CT/8 kHz VT, select the next largest size drive controller. If the duty cycle does not exceed 60% (36 s maximum for a 60 s cycle), this is not necessary. (2) Class 10 electromechanical for 1 hp @ 460 V. Specifications M-Flex
