Parameter description
2: Serial communication control ("LOCAL/REMOT" indicator blinks)
Start & stop is controlled by the communication serial port. Modbus card is inbuilt.
F0.03 Frequency reference 1 (Freq. ref. 1) Range: 0 - 8 [0]
F0.04 Frequency reference 2 (Freq. ref. 2) Range: 0 - 8 [0]
0: Digital setup
The initial value is the value of F0.06 "UP/DOWN preset frequency". The reference
frequency value can be changed through the keys
function terminals UP/DOWN (select through F0.08). The modification recording
options in case of power failure is determined by the parameter F0.09. If setting is
not saved in power failure, the reference frequency value will recover to default
value F0.06 "UP/DOWN Preset Frequency" upon power recovery.
1: Terminal Al 1
2: Terminal AI2
It means that the frequency is determined by the analog input terminal. AI1 refers to
voltage input 0-10V. AI2 can be used as either voltage input of 0V-10V or current
input of 0/4mA ~20mA, which can be selected by the AASW1/AASW2 DIP switch on
the control board.
3: PULSE setup
The reference frequency is given by the terminal pulse. Pulse signal reference
specification: voltage 9V -30V and frequency range 0kHz ~50kHz.
4: Communication
It means that the frequency source is given by the host computer via the
communication mode.
5: MS (Multi-step) Speed
When this mode is selected, group F6 "Input Terminals" and Group F9 "Multi-step
speed and PLC" parameters shall be set to determine the relative relationship
between the reference signal and the reference frequency.
6: Programmable Logic Controller (PLC)
When PLC mode is selected, Group F9 "Multi-step Speed and PLC" parameters shall be
set to determine the reference frequency.
7: PID
When PID is selected to be reference, Group F8 "PID Parameters" shall be set. The
running frequency of the drive is the value after PID regulation.
