PID control 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 key.: 0.0 to 100%
Voltage input (Terminal 12) : 0 to 10Vdc
Current input (Terminal C1) : 4 to 20mAdc
Multistep frequency setting : Setting freq./Max. freq.x100%
RS485 : Setting freq./Max. freq.x100%
Feedback signal
Terminal 12 (0 to +10Vdc or +10 to 0Vdc)
Terminal C1(4 to 20mAdc or 20 to 4mAdc)
Second motor’s The V/f pattern of the second motor can be internally set for selection by means
setting 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.
Energy saving Weak magnetic flux can be set for small loads for operation with an increased
operation motor efficiency.
During The keypad panel can be extended. (Optional 2m extension cable is available.)
