Example Speed Calculation

Example Speed Calculation

Switching speed is a function of pulse widths, sensing delays, the state of the chosen channels, the sequence of relays driven and the power suply recovery time. A sample program and timing diagram are provided to help the user minimize switching time, since the user determines pulse widths, sensing delays and which channels are opened or closed.

Table 4-7shows which connectors (J1 to J31) are on the same drive lines. Refer to the installation instructions (Figure 2-6 on page 2-7) to wire your relay into the arbitrary positions of OPEN and CLOSE.

Table 4-7 Relay Drive Sequence

Drive Line	Connector Locator	Channel List
1	J1, J2, J3, J4	00, 01, 02, 03
2	J5, J6, J7, J8	04, 05, 06, 07
3	J9, J10, J11, J12	08, 09, 10, 11
4	J13, J14, J15, J16	1 2, 13, 14, 15
5	J17, J18, J19, J20	16, 17, 18, 19
6	J21, J22, J23, J24	20, 21, 22, 23
7	J25, J26, J27, J28	24, 25, 26, 27
8	J29, J30, J31	28, 29, 30

The following program, along with Figure 4-1 on page 4-77,can be used to learn how to determine switching speed. It is intended to show how the drive line architecture of the switch driver/driver board(s) and the programmed variables of :DELay,:WIDTh and TRIG:SEQ:DEL can be used to calculate the total switching time for any switching operation.

Recall that the channel number is a three digit number where the first digit is the driver card number. Channel 130 is channel 30 on driver card 1. Channel 825 is channel 25 on driver card 8.
