Principal Control System Sinusoidal PWM control
Control Output voltage regulation Same as power line.
Specifications Output frequency 0.01 to 400 Hz (0.1 to 80Hz default setting)*. 800 Hz operation
possible.
Frequency setting 0.1Hz from operating panel input (60Hz base), 0.01Hz from analog
input (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 Torque
characteristics Control and automatic energy-saving control/maximum voltage
frequency 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 10kHz
Transistor type Insulated gate bipolar (IGBT)
Output voltage regulation Drive can be programmed to fix max. output volts, let max. float with
input voltage, or set max. to input voltage sensed at power-up.
Dynamic braking
Feature not available in H3 drives above 30 HP.
Frequency Input signals 3k ohms potentiometer (1k ohm to 10k ohm-rated potentiometer
can be connected). 0 to 10Vdc (Zin=33k ohm), ±10 Vdc (Zin=67k
ohm), +/-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/decel
functions pattern selection
Forward or reverse run Forward run when F-CC closed (default); reverse run when R-CC
closed (default); reverse run when both closed (default); coast-stop
when ST-CC opened (default); emergency coast stop by a
command from operating panel or terminal block; 3-wire control and
motorized speed pot programmable functions.
Jogging run Jog run from panel with JOG mode selection. Terminal
block operation possible with parameter settings.
Multispeed run Set frequency plus 15 preset speeds possible with combinations of
CC, SS1, SS2, SS3, and SS4 (default functions).
Retry When a protective function is activated, the system checks main
circuit devices, and attempts to restart. Settable to a maximum
of 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 block
control/repetitive run possible.
DC injection braking Braking starting frequency adjustment (0 to 120Hz), braking current
adjustment (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 parameters
Blind function Select to display needed parameter groups and parameters
User-defined defaults User's parameter values can be saved into a default library. User
can then default drive to Toshiba's values or to the user's own.
