Example 2: Power Factor Interface Setpoint
The setpoint for the power factor control is set as a value between -710 to -999, 1000, 999 to 710. A negative
value is capacitive, a positive value is inductive, 1000 = cosphi 1. Other values are not accepted by the unit. This
setpoint will be accepted, if the power factor setpoint is selected via ToolKit.
The power factor setpoint value must be written to parameter 7640.
Example:
A power factor of 1 = 1000 (dec) = 03E8 (hex) is to be transmitted.
Modbus address = 40000 + (Par. ID + 1) = 40509.
Modbus length = 1 (UNSIGNED 16).
The following Modscan32 screenshot shows the settings made to parameter address 7640 in ModScan32.
