Rich and Flexible Functions
Multiple Frequency Reference Modes, Flexible and Convenient for
Operation
Operation panel reference (digital reference). The operation panel can be used to
conduct
∨/∧ adjustm ent on the frequency reference.
Terminal reference:
1)
Analog AI1/AI2: 0 to 10V or 0 to 20mA
2)
Analog AI3: -10V to 10V
3)
Pulse frequency X7/DI: 0.2Hz to 50kHz
4)
Xi terminal: UP/DN mode independent, able to superpose with any other
frequency reference mode
Communication mode reference: International standard Modbus protocol.
The above reference modes can be switched online.
Multiple Channels for Reference and Feedback
Under the open loop mode and analog feedback close loop mode, the reference value
can define the main and auxiliary calculation relation:
1)
Main ref auxiliary reference
2)
Main reference - auxiliary reference
3)
Main ref auxiliary reference -50%
4)
Max (main reference, auxiliary reference)
5)
Min (main reference, auxiliary reference)
The sign of the main and auxiliary reference calculation (positive or negative) can
automatically determine the rotation direction of the motor.
Under the analog feedback close loop mode, the feedback value can also define the
main and auxiliary calculation relation before it enters the process PID for adjustment
control.
It is especially suitable for:
The continuous and automatic production lines, such as paper making, printing and
dyeing, packaging and printing.
The temperature difference and pressure difference applications, such as the chilled
water control of the central air conditioner, the water supply system.
Digital Operation Panel
Button type and shuttle type selectable, RS485 communication mode, standard
network port connection.
The button layout complies with the human engineering principle. One-button function
code access and exit, making it easy for the operation.
The standard configuration operation panel can realize parameter copy and remote
control function (maximum length: 500m).
