Specification

 

 

 

Control system

Sinusoidal PWM control

 

 

 

Rated output voltage

Adjustable within the range of 50 to 660V by correcting the supply voltage (not adjustable above the input

 

 

 

 

voltage)

 

 

 

Output frequency range

0.5 to 200.0Hz, default setting: 0.5 to 80Hz, maximum frequency: 30 to 200Hz

 

 

 

Minimum setting steps

0.1Hz: analog input (when the max. frequency is 100Hz), 0.01Hz: Operation panel setting and

 

 

functions

of frequency

communication setting.

 

 

Frequency accuracy

Digital setting: within ±0.01% of the max. frequency (-10 to +60°C)

 

 

 

 

 

 

 

Analog setting: within ±0.5% of the max. frequency (25°C ±10°C)

 

 

 

Voltage/frequency

V/F constant, variable torque, automatic torque boost, vector control, automatic energy-saving, PM motor

 

 

control

characteristics

control. Auto-tuning. Base frequency (25 - 200Hz) adjusting to 1 or 2, torque boost (0 - 30%) adjusting to

 

 

 

1 or 2, adjusting frequency at start (0.5 - 10Hz)

 

 

Frequency setting

External frequency potentiometer (connectable to a potentiometer with a rated impedance of 1 - 10k), 0

 

 

Principal

frequency

functions: analog input (VIA and VIB) and communication command.

 

 

 

signal

- 10Vdc (input impedance: VIA/VIB=30k, 4 - 20mAdc (Input impedance: 250).

 

 

 

Terminal board base

The characteristic can be set arbitrarily by two-point setting. Possible to set individually for three

 

 

 

 

 

 

 

 

Frequency jump

Three frequencies can be set. Setting of the jump frequency and the range.

 

 

 

Upper- and lower-limit

Upper-limit frequency: 0 to max. frequency, lower-limit frequency: 0 to upper-limit frequency

 

 

 

frequencies

 

 

 

 

PWM carrier frequency

Adjustable within a range of 6.0 to 16.0Hz (default: 8 or 12kHz).

 

 

 

PID control

Setting of proportional gain, integral gain, differential gain and control wait time. Checking whether the

 

 

 

 

amount of processing amount and the amount of feedback agree.

 

 

 

Acceleration/decelerati

Selectable from among acceleration/deceleration times 1 and 2 (0.0 to 3200 sec.). Automatic

 

 

 

on time

acceleration/deceleration function. S-pattern acceleration/deceleration 1 and 2 and S-pattern adjustable.

 

 

 

 

Control of forced rapid deceleration and dynamic rapid deceleration

 

 

 

DC braking

Braking start-up frequency: 0 to maximum frequency, braking rate: 0 to 100%, braking time: 0 to 20

 

 

 

 

seconds, emergency DC braking

 

 

 

Input terminal function

Possible to select from among 57 functions, such as forward/reverse run signal input, operation base

 

 

 

(programmable)

signal input and reset signal input, to assign to 4 input terminals. Logic selectable between sink and

 

 

specifications

 

source.

 

 

Output terminal

Possible to select from among 58 functions, such as upper/lower limit frequency signal output, low speed

 

 

functions

switching between forward run and reverse run can be done from one of the three control units: operation

 

 

 

detection signal output, specified speed reach signal output and failure signal output, to assign to FL

 

 

 

(programmable)

relay output, RY output terminals.

 

 

 

Forward/reverse run

The RUN and STOP keys on the operation panel are used to start and stop operation, respectively. The

 

 

Operation

 

panel, terminal board and external control unit.

 

 

Retry operation

Capable of restarting automatically after a check of the main circuit elements in case the protective

 

 

 

Preset speed operation

Base frequency + 7-speed operation possible by changing the combination of 3 contacts on the terminal

 

 

 

 

board.

 

 

 

 

function is activated. 10 times (Max.) (selectable with a parameter)

 

 

 

Various prohibition

Possible to write-protect parameters and to prohibit the change of panel frequency settings and the use

 

 

 

settings

of operation panel for operation, emergency stop or resetting.

 

 

 

Auto-restart operation

In the event of a momentary power failure, the inverter reads the rotational speed of the coasting motor

12

 

 

 

and outputs a frequency appropriate to the rotational speed in order to restart the motor smoothly. This

 

 

 

function can also be used when switching to commercial power.

 

 

Drooping function

The motor is allowed to “slip” according to the load torque current.

 

 

 

 

 

 

 

 

Failure detection signal

1c-contact output: (250Vac-0.5A-cosФ=0.4)
