-RPF
Remote programming frequency. DC voltage input 0 to 10 VDC or 0 to 5
VDC for 0 to 800 Hz output frequency programming. Input impedance is
20 KOhm.
This option is mutually exclusive with the –LKS and –EXT option. Not
available with the FC option.
-FC
Frequency control option
-WHM
Watt-hour measurement option.
2.9 EXT Option - Supplemental Specifications
When the EXT option is installed, the amplifier is used in an open loop mode and none of the regular compact iX
Series output specifications apply. This option also precludes the presence of the –RPV and –RPF option.
An external signal input is provided for each phase. The phase A EXT input pins is also used on the Auxiliary I/O
connector for the RPVA option so the RPV and EXT options are mutually exclusive. The voltage reference (VOLT
REF) on the CONTROL screen of the power source controller must be set to EXT to use this feature. See section
8.4 for EXT option operating instructions.
