Set the following parameters to use pulse input for speed command:
00-05=7
03-02=26
03-28=1 (adjust if required)
03-27: Not used.
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 650Hz (00-12=650.00), and 03-28=0.2.
Inverter frequency is 2000 x 0.2 = 400.00Hz
Notes:
- In this mode, pulse input frequency range is 0.01 kHz to 200Hz.
- Pulse input can only be selected for terminal S3
- PLC common is COM terminal on TM2

Fire Mode Function
When active inverter runs at maximum speed (parameter 00-12) ignoring any protective functions. Fire Mode
function can be used for applications following a fire where it is necessary for a motor to continue running without
interruption.
Example:
Smoke exhaust 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. TWMC bares
no responsibility for direct or indirect damages or loss incurred as a result of using this function.
Warranty is void when inverter damage is caused by using Fire Mode.
