16. 2 PWM Input The PW M signal coming in to the PMD X 106 is idle at a logic low and active at a logic high The duty cycle is measured as active duration idle duration active duration The PW M frequency must be between 5 Hz and 1 000 Hz to be considered valid The PW M duty cycle should be between 5 to 99 9 The PMDX 106 has a delay when detecting a valid incoming PW M This delay is noticeable only at slower PW M frequencies typically 5 to 10 Hz The PMDX 106 takes 2 PW M periods to measure the PW M duty cycle It then requires 3 successive PW M measurements with valid frequencies to enable the output The PMDX 106 considers absence of a PW M signal i e 0 or 100 duty cycle to be a stop command W hen detecting a loss of PW M there is a delay of approximately one third of a second from the actual loss of PW M signal until the PMDX 106 commands the VSD to stop The PMD X 106 is an open loop speed control interface This type of interface has no way of knowing about or correcting for speed deviations Most applications will achieve 596 to 1096 accuracy but no guarantee of accuracy can be given because of the number of factors involved The PMDX 106 is designed to provide speed commands over a range of 5 to 100 of full rated speed Settings below 596 may have significant error Many VSDs will enforce a minimum speed greater than 5 as much as 3096 to cool and protect the motor In this case the motor will not star
