Example
For example, in the diagram below, a digital output is configured for P935 [Drive
Status 1], Bit 27 “Cur Limit,” the On Time is programmed for two seconds and
the Off Time is programmed for 0 seconds.
Status
The [Dig Out Sts] parameter displays the status of the digital outputs and can be
used for troubleshooting the digital outputs. When the bit in associated with the
digital output is on, this means that the logic in the drive is telling that digital
output to turn on. When the bit associated with the digital input is off, this
means that the logic in the drive is telling that digital output to turn off.
