See “How Power Factor is Stored in the Register” on page 128.

The alternate storage method for power factor (PF) is useful for outputting PF on analog outputs. The PF value is stored as a positive value between 0 and 2, centered around 1 (unity). A value of 0 lagging maps to 0; -0.999 maps to 0.999;0.999 leading maps to 1.001; and 0 leading maps to 2. The alternate PF is also stored with a scale factor 0.001.

These configuration registers require that you enter the setup mode to change the register’s contents. Issue command 9020 to enter setup mode and 9021 to exit setup mode. See “Using the Command Interface to Change Configuration Registers” on page 187 for instructions on

￿how to use the setup-mode commands.

Quantity available for 4-wire system only. Value set to -32,768 if not available.
