4-41
Example 2:
Pulse input frequency is 100Hz (03-27=0.10), duty cycle is 30%, frequency upper limit is 50Hz
(00-12=50.00), and 03-28=2
Inverter frequency is 30% x 50.00 x 2 = 30.00Hz
Example 3:
Pulse input frequency is 200Hz (03-27=0.20), duty cycle is 15%, frequency upper limit is 599Hz
(00-12=599.00), and 03-28=5
Inverter frequency is 15% x 599.00 x 5 = 499.25Hz
Note 1: In this mode, the frequency range of pulse input is 0.01 kHz to 0.20 kHz.
Note 2: The above examples are under assumption of a NPN input configuration. If PNP is used,
the relationship between duty cycle and inverter frequency is reversed, that is, 20% duty cycle
means 80% inverter frequency
21)03- 02=【26】Pulse Input-Frequency Measure (S3)
When 03-02=26, S3 is the input port of the frequency measurement function. Parameters setting and
applying are as the followings:
00-05=7 (Pulsed Speed Control)
03-02=26 (S3 is the pulse input- frequency measurement)
03-28=0.01~9.99
(Inverter Frequency _F=f*(3-28) Hz, and below the Frequency Upper limit.
f: Pulse Input Frequency
.)
To adjust speed through pulse input frequency, set parameters as follows:
00-05=7; 03-02=26; 03-28=1 (as per actual need); 03-27 is not used.
Along with the pulse input frequency, inverter frequency is varied.
Example 1:
Pulse input frequency is 20Hz, frequency upper limit is 50Hz (00-12=50.00), and 03-28=1
Inverter frequency is 20.00Hz
Example 2:
Pulse input frequency is 45Hz, frequency upper limit is 50Hz (00-12=50.00), and 03-28=1
Inverter frequency is 45.00Hz
Example 3:
Pulse input frequency is 55Hz, frequency upper limit is 50Hz (00-12=50.00), and 03-28=1
Inverter frequency is 50.00Hz
Example 4:
Pulse input frequency is 2000Hz, frequency upper limit is 599Hz (00-12=599.00), and 03-28=0.2
Inverter frequency is 2000 x 0.2 = 400.00Hz
Note: In this mode, the frequency range of pulse input is 0.01 kHz to 10.00 kHz.
※ Pulse input can only select S3 and when S3 is the terminal of pulse input, PLC output
ground need to connect to COM from TM2.
22) 03- 00~03- 05=【27】 Enable KEB Function
Once the KEB enable input is activated the decelleration time to stop will be according to parameter 07-14.
23) 03- 00~03- 05=【28】Fire Mode Function
Fire Mode function can be used for applications where following a fire it is necessary for a motor to
continue running, without interruption by the normal Inverter protection functions.
Example of such application is smoke extract fans used in buildings for fire evacuation.
Caution
The correct use of this function is the responsibility of the installer of the fire safety system.
Teco will bare no responsibility for direct or indirect damages or loss incurred as a result of
use of this function.
When inverter damage is caused by use of Fire Mode, inverter will lose its warranty.
