Chapter 2 Replacement Considerations
You can assign the inputs that are listed as — for any of these functions.
• Abort Homing
• Abort Index
•Start Homing
•Start Index
•Fault Reset
• Home Sensor
• Index Select
The digital inputs are optically isolated and sink up to 24V DC. Electrical
details are shown in Table 21
.
Kinetix 5100 Drives
The Kinetix 5100 drives have eight standard inputs and two-high speed inputs,
both with configurable functions. The digital inputs on Kinetix 5100 drives
have the same physical characteristics. Table 22
shows the Kinetix 5100 digital
inputs physical characteristics.
