Basic Models
1. PPT 1500 -220 -T1-1
This means, it 
    has a 1500W maximum controllable power with supply voltage of 220V single 
    phase. This model has input A as enable and input B as override speed. That 
    is, if input B is made active while input A is active the motor shall run 
    at full speed. The typical applications include conveyor belts where the job 
    can be accelerated by pressing the override key.
    
2. 
    PPT 1500 -220 -TI-2
    This means, it has a 1500W maximum controllable power with supply voltage 
    of 220V single phase. This model has input A as enable and input B as crawl 
    speed. That is, if input B is made active while input A is active the motor 
    shall run at y. of full speed. The typical applications include machine tools 
    where the job has to be inched.
