9 -4 Common SpecificationsThe following specifications apply to both 200 V and 400 V Class Inverters.* 1. Rotational autotuning must be performed to ensure obtaining the specifications given for flux or open-loop vector control.* 2. Increase the Inverter capacity if loads exceeding these current values are expected.* 3. Only VT can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters.* 4. The speed control accuracy depends on the installation condition and types of motor used. Contact your Yaskawa representative for details.* 5. When connecting a Braking Resistor or Braking Resistor Unit, set L3-04 (Stall prevention selection during deceleration) to 0 (disabled). Stopping may not bepossible in the specified deceleration time if this function is not disabled.* 6. Derating is required for applications that use repetitive loads. (Refer to page 10-6 for details.)Table 9.3 Common SpecificationsModel NumberCIMR-F7A SpecificationControl method Sine wave PWM, Open-loop vector control, V/f control, V/f with PG control (switched by constant setting)Torque characteristicsCT selected (low carrier, constant torque applications): 150% /0.5 Hz (Open-loop vector control)VT selected (high carrier, variable torque applications): 120%/0.5 Hz (Open-loop vector control)Speed control range 1:100 (Open-loop vector control), *1Speed control accuracy *4 ±0.2% (25°C ± 10°C, Open-loop vector control), *1Speed control response 5 Hz (Open-loop vector control),Torque limits Provided for vector control only (4 quadrant steps can be changed by constant settings.)Torque accuracy *4 ±5%Frequency control range 0.01 to 150 Hz (CT selected.), 0.01 to 400 Hz (VT selected.)Frequency accuracy (tem-perature characteristics)Digital references: ± 0.01% (-10°C to +40°C)Analog references: ±0.1% (25°C ±10°C)Frequency setting resolution Digital references: 0.01 HzAnalog references: 0.06 Hz/60 Hz (+10 bit)Output frequency resolution 0.001 HzOverload capacity and max-imum current *2 CT selected (low carrier, constant torque applications): 150% of rated output current per minute *3, *6VT selected (high carrier, variable torque applications): 120% of rated output current per minute *6Frequency setting signal , 0 to 10 V, 4 to 20 mA, pulse trainAcceleration/Decelerationtime 0.01 to 6000.0 s (4 selectable combinations of independent acceleration and deceleration settings)Braking torque Approximately 20% (Approximately 125% with Braking Resistor option *5, braking transformer built into 200 V and 400 V ClassInverters for 18.5 kW or less.)Main control functionsRestarting for momentary power loss, speed searches, overtorque detection, torque limits, 17-speed control (maximum), accelera-tion/deceleration time changes, S-curve acceleration/deceleration, 3-wire sequence, autotuning (rotational or stationary), dwellfunctions, cooling fan ON/OFF control, slip compensation, torque compensation, jump frequencies, upper and lower limits forfrequency references, DC braking for starting and stopping, high-slip braking, PID control (with sleep function), energy-savingcontrol, MEMOBUS communications (RS-485/422, 19.2 kbps maximum), fault reset, , function copying,, etc.Motor protection Protection by electronic thermal overload relay.Instantaneous overcurrentprotection Stops at approx. 200% of rated output current.Fuse blown protection Stops for fuse blown.Overload protection CT selected (low carrier, constant torque applications): 150% of rated output current per minute *3VT selected (high carrier, variable torque applications): 120% of rated output current per minuteOvervoltage protection 200 Class Inverter: Stops when main-circuit DC voltage is above applox. 410 V.400 Class Inverter: Stops when main-circuit DC voltage is above applox. 820 V.Undervoltage protection 200 Class Inverter: Stops when main-circuit DC voltage is below applox. 190 V.400 Class Inverter: Stops when main-circuit DC voltage is below applox. 380 V.Momentary power lossridethruStops for 15 ms or more.By selecting the momentary power loss method, operation can be continued if power is restored within 2 s.Cooling fin overheating Protection by thermistor.Stall prevention Stall prevention during acceleration, deceleration, or running.Grounding protection Protection by electronic circuits.
