Monitor Reference - Mitsubishi Electric A800 Plus Series Function Manual

Monitoring of dedicated functions
Negative output selection for monitoring (Pr.290)
• A negative output can be selected for the monitor display of terminal AM (analog voltage output), the operation panel, and
a communication option. For the monitor items for which negative output is possible, refer to the monitor list.

∗1 RS-485 communication does not support the negative indication.
Terminal DA1 output polarity selection (Pr.159)
• When the FR-A8AZ is installed, Pr.159 DA1 output sign selection can be used to select the polarity of the output through
terminal DA1.
