Used for selecting frequency reference given auxiliary channel. The combination mode of auxiliary and main
channel programmed by
[E-05]
parameters
0: Operator keypad digital given
Auxiliary frequency given is set by up and down arrow key of keypad or
parameters
[E-16]
configuring.
1: Potentiometer of keypad
Auxiliary frequency given determined by potentiometer of keypad.
2: Terminal VS1 analog voltage 0-10V
Auxiliary frequency given is determined and modified by control terminal
VS1 analog input.
3: Terminal AS analog current signal 4-20mA
Auxiliary frequency given is determined and modified by (AS)
analog current input.
4: Terminal VS2 analog voltage -10-10V
Auxiliary frequency given is determined and modified by control
terminal VS2 analog input.
5: Pulse train signal
Auxiliary frequency given is determined and modified by control terminal (PUL) analog input.
6: RS485 communication port
Auxiliary frequency given is determined by receiving signal of (A+) and (B-) of
RS485 communication port.
7: Up and Down control
Auxiliary frequency given is determined by increasing UP and decreasing DOWN
terminal connecting or disconnecting( ON/OFF) with COM terminal; each of multi- terminal (X1-X6) can be
programmed by frequency UP terminal and DOWN terminal, refer to
[F-01-F-06 ]
in detail; Initial frequency of up
and down terminal control can be configured, please refer to parameter
[F-07]
LED ten digit option and
[F-70]
.
8: General PID operation
Selects it use to set up general PID close loop control system. When it has been applied,
the
[H-16]
present setting value can be modified by up and down arrow button of keypad.
9: Constant pressure PID control
It can be used to set up constant pressure PID control (constant pressure water
supply system etc) close loop system, the
[H-16]
present setting value can be modified by up and down arrow
