Detail specifications
This function can control flowrate, pressure, etc. with analog feedback signal|
The reference and feedback values are displayed in %.
Reference signal
Keypad operation key and
Voltage input (Terminal 12)
Current input (Terminal C1)
Multistep frequency setting
RS485
Feedback signal
Terminal 12 (0 to +10Vdc or +10 to 0Vdc)
Terminal C1(4 to 20mAdc or 20 to 4mAdc)
The V/f pattern of the second motor can be internally set for selection by means
of an external signal.
The constant of the second motor can be internally set for selection by means of
an external signal.
The electronic thermal overload relay of the second motor can be internally set
for selection by means of an external signal.
Weak magnetic flux can be set for small loads for operation with an increased
motor efficiency.
The keypad panel can be extended. (Optional 2m extension cable is available.)
7-segment LED display items
• Set frequency • Output frequency
• Output current • Motor r/min
• Output voltage • Line speed
(A soft filter is provided to attenuate the fluctuation in the displayed value.)
A charge lamp indicates power supply.
The function code and data code are displayed.
