Parameter Description Min Max
On-state input voltage
Input voltage difference between the + input and the -
input that is detected as an On-state.
2.8V 3.7V
Off-state input voltage
Input voltage difference between the + input and the -
input that is detected as an Off-state.
1V -3V
Signal frequency (high
frequency differential driver
input drive)
Input frequency of the HF_PULS or HF_SIGN inputs.
Count frequency is four times this frequency for A/B type
inputs, and equal to this frequency for Step/Direction and
Step Up/Down inputs.
