Interpulse period following auto reverse
You can configure the minimum amount of time the technology module must pause the pulse
output following reversal of the direction of rotation. After the interpulse period elapses, the
pulse output is resumed.
You can specify the following values for the interpulse period:
● 0 (default)
● 1 ms
● 4 ms
● 10 ms
Input delay
This parameter can be used to suppress signal noise at the digital inputs of a channel.
Changes to the signal are only detected if they remain stable for longer than the configured
input delay time.
You can specify the following values for the input delay:
● None
(input delay of 4 μs, minimum pulse width of 3 μs)
● 0.05 ms
● 0.1 ms (default)
● 0.4 ms
● 0.8 ms
● 1.6 ms
● 3.2 ms
● 12.8 ms
● 20 ms
Note
If you select the "None" or "0.05 ms" option, you have to use shielded cables for connection
of the digital inputs.
