Input Response Time
Input response time is the delay that takes place after a signal is received but before the motion
occurs at the motor shaft. The diagram below shows the comparative response between an
input and the start of motion when no serial communication is occurring. The typical response
time for starting an index is 4 ms with a maximum time of 7 ms.

High Speed Inputs
As with all inputs, lines 1 and 2 have an average response time of 4 ms. However, when inputs
1 and 2 are used the drive remembers when the signal was received and increases the accel
rate of the motor to reach maximum velocity sooner than at the set accel rate. The effect is a
response time of 100 ms average.
High speed inputs should not be wired together or filtered as unpredictable response times
and assigned function activation will result.
