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.
Current consumption of the CPU module
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
9) Voltage drop at slot 7: V7
10) Total voltage drop at the main base unit: VK
