BASE UNIT AND EXTENSION CABLE6.
(3) Receiving voltage calculation method
(a) Calculation of voltage drops with the main base unit (A1S32B, A1S33B,
A1S35B, A1S38B)
Resistive value with the main base unit is 0.007 per slot. Sum up the voltage
drops of each slot.
1) Voltage drop at the CPU module: V
CPU
2) Voltage drop at slot 0: V0
3) Voltage drop at slot 1: V1
4) Voltage drop at slot 2: V2
5) Voltage drop at slot 3: V3
6) Voltage drop at slot 4: V4
7) Voltage drop at slot 5: V5
8) Voltage drop at slot 6: V6
V6=0.007 (I6 + I7 + I8 + I9 + I10 + I11 + I12 + I13 + I14 + I15)
9) Voltage drop at slot 7: V
