TOSHIBAPrincipal Control System Sinusoidal PWM controlControl Output voltage regulation Same as power line.Specifications Output frequency 0.01 to 400 Hz (0.1 to 80Hz default setting)*. 800 Hz operationpossible.Frequency setting 0.1Hz from operating panel input (60Hz base), 0.01Hz from analoginput (60Hz base, 12-bit/0 to 10Vdc), 0.01Hz from computer interface(60Hz base)Frequency accuracy Analog input: ±0.2% of the maximum output frequency (25°C±10°C),Digital input: ±0.01% (25°C±10°C)Voltage/frequency Constant V/f, variable torque, automatic torque boost, True Torquecharacteristics Control and automatic energy-saving control/maximum voltagefrequency adjustment (25 to 400Hz), torque boost adjustment(0 to 30%), start-up frequency adjustment (0 to 10Hz).PWM carrier frequency Adjustable between 0.5 and 10kHzTransistor type Insulated gate bipolar (IGBT)Output voltage regulation Drive can be programmed to fix max. output volts, let max. float withinput voltage, or set max. to input voltage sensed at power-up.Dynamic brakingFeature not available in H3 drives above 30 HP.Frequency Input signals 3k ohms potentiometer (1k ohm to 10k ohm-rated potentiometercan be connected). 0 to 10Vdc (Zin =33k ohm), ±10 Vdc (Zin =67kohm), +/-5 Vdc (Zin =34k ohm), 4 to 20mAdc (Zin =500 ohm)Set point control (PID) Proportional gain, integral gain, anti-hunting gain, lag time constant,and PID error limit adjustments.Operating Accel/decel time 0.1 to 6000 secs, accel/decel time 1 or 2 selection, accel/decelfunctions pattern selectionForward or reverse run Forward run when F-CC closed (default); reverse run when R-CCclosed (default); reverse run when both closed (default); coast-stopwhen ST-CC opened (default); emergency coast stop by acommand from operating panel or terminal block; 3-wire control andmotorized speed pot programmable functions.Jogging run Jog run from panel with JOG mode selection. Terminalblock operation possible with parameter settings.Multispeed run Set frequency plus 15 preset speeds possible with combinations ofCC, SS1, SS2, SS3, and SS4 (default functions).Retry When a protective function is activated, the system checks maincircuit devices, and attempts to restart. Settable to a maximumof 10 times; wait time adjustment (0 to 10 secs)Soft stall Automatic load reduction during overload (Default setting: OFF).Automatic restart A coasting motor can be smoothly restarted (Default setting: OFF).Pattern Run 4 groups of 8 patterns each can be set to the 15 preset speed values.A maximum of 32 different patterns can be run; terminal blockcontrol/repetitive run possible.DC injection braking Braking starting frequency adjustment (0 to 120Hz), braking currentadjustment (0 to 100%), braking time adjustment (0 to 10secs),emergency stop braking function, motor shaft stationary control.Upper/Lower limit Limits the frequency between the set values (0 to max. frequency).Can be indicated via output contact closure.Frequency jump 3 jump frequency settings (each with unique band settings)Edit function Easy access user group containing all changed parametersBlind function Select to display needed parameter groups and parametersUser-defined defaults User's parameter values can be saved into a default library. Usercan then default drive to Toshiba's values or to the user's own.3 - 2* Consult the factory for applications above 80 Hz.ITEM STANDARD SPECIFICATIONSStandard SpecificationsSpecifications PrecautionsWiringJumpersPanelKeypadParametersProgrammingServiceDimensionsIndex Inspection
