Note -
1. When inputting current signal to terminal AI 2, turn the voltage / current switch SW2 to I (factory setting),
and set 04-00 = 1, or 3 (AI2 = 4 ~ 20mA).
2. When inputting voltage to terminal AI2, turn the voltage / current switch SW2 to V position (factory setting)
and set 04-00 = 0, or 2 (AI2 = 0 ~ 10V).
3. Set correctly 04-00 based on AI1input signal.
(3) 00-05=2:
Use the functions of increasing frequency and decreasing frequency of terminal DI to control
frequency command. Please refer to 03-00 ~ -03-07 parameter description to understand the
relevant functions.
(4) 00-05=3:
Use the PLC of MODICON series or other related devices using MODBUS RTU protocol to input
frequency reference through RS-485 communication port. Please refer to parameter 09--
communication group to understand more communication commands of RS-485.
(5) 00-05=4:
Set 03-30 (pulse input function selection) to 0 (frequency reference), you can use pulse input as
frequency reference command and set 03-32 (pulse input ratio) to 100%. Please refer to
descriptions of parameters 03-30 ~ 03-34 to understand detailed description of using input pulse.
The frequency reference function of pulse input is shown as Figure 4.3.5.
Figure 4.3.5 The frequency reference function of pulse input
(6) 00-05=5:
Using PID function as a source of frequency reference, please refer to the relevant descriptions of
parameters 10-00 ~ 10-29.
00- 08 Communication frequency command
Range
【0.00~400.00】Hz
【0.0~1200.0】Hz
(when 00-31 = 1)
¾ This parameter is used to read the communication frequency command (read-only).
¾
This parameter is only effective in communication mode.
00- 09 Communication frequency command memory
Range
【0】: Do not store the communication frequency command before power off
【1】: Store the communication frequency command before power off
¾ This parameter is only effective in communication mode.
00-12 Frequency upper limit
Range
【0.1~109.0】%
00-13
Frequency lower limit
Range
【0.0~109.0】%
The upper limit and lower limit of frequency reference is based on maximum 100% of output reference
01-01 (Fmax) or 01-16, with 0.1% as increasing base.
. Set value of 00-12 shall exceed 00-13, otherwise it will display error information of Range set by “SE01”
(Set Range Error).
