Appendix C.1.2 VIB Features

The VIB provides fully isolated inputs and outputs that operate on a wide range of voltages for maxi- mum flexibility. Each I/O is programmed to perform a dedicated function. The specific function of each I/O is listed below in Table 34.

Table 34 VIB I/O functions

I/O	Interface	VIB Designation	Description
1	Output 1	Off1	Mode = Off (RPM < 200)
2	Output 2	Startup	Mode = Startup (200 < RPM < 25000)
3	Output 3	Charge	Mode = Charge (RPM > 25000)
4	Output 4	SOC >= 0%	State of Charge >= 0%
5	Output 5	SOC >= 12.5%	State of Charge >= 12.5%
6	Output 6	SOC >= 25%	State of Charge >= 25%
7	Output 7	SOC >= 37.5%	State of Charge >= 37.5%
8	Output 8	SOC >= 50%	State of Charge >= 50%
9	Output 9	SOC >= 62.5%	State of Charge >= 62.5%
10	Output 10	SOC >= 75%	State of Charge >= 75%
11	Output 11	SOC >= 87.5%	State of Charge >= 87.5%
12	Output 12	Ready	Mode = Ready (SOC >= 99%)
13	Output 13	Discharge	Mode = Discharge
14	Output 14	Shutdown	Mode = Shutdown
15	Output 15	Warning	Mode = Warning
16	Output 16	Fault	Mode = Fault
17	Input 1	Start2	Start Command Issued
18	Input 2	Shutdown2	Shutdown Command Issued
19	Input 3	Clear Fault	Clear Fault Command Issued
20	Output 17	Rotor Temp	Rotor Temp High

1.The “OFF” signal is also used to indicate if the temperature of the rotor is too warm. If the “OFF” output is asserted while any of the other “Mode” outputs are asserted (STARTUP, CHARGE, SHUTDOWN, DISCHARGE) or while the State of Charge is >= 0%, then the rotor is too warm and must cool before charge resumes.

2.“START” and “SHUTDOWN” inputs are mutually exclusive. If they are asserted simultaneously, both will be ignored.

For reference, the I/O designations are shown in Figure 117. The number of each I/O is also labeled on the circuit board.
