Description
9:0
PHCALVAL

If current channel compensation is necessary, these bits can vary only between 0 and 383.
If voltage channel compensation is necessary, these bits can vary only between 512 and 575.
If the PHCALVAL bits are set with numbers between 384 and 511, the compensation behaves
like PHCALVAL set between 256 and 383.
If the PHCALVAL bits are set with numbers between 512 and 1023, the compensation
behaves like PHCALVAL bits set between 384 and 511.

Description
0
AWSIGN
0
0: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase A is positive.
1: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase A is negative.
1
BWSIGN
0
0: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase B is positive.
1: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase B is negative.
2
CWSIGN
0
0: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase C is positive.
1: if the active power identified by Bit 6 (REVAPSEL) bit in the ACCMODE[7:0] register (total of
fundamental) on Phase C is negative.
3
SUM1SIGN
0
0: if the sum of all phase powers in the CF1 datapath is positive.
1: if the sum of all phase powers in the CF1 datapath is negative. Phase powers in the CF1
datapath are identified by Bits[2:0] (TERMSEL1) of the COMPMODE[15:0] register and by
Bits[2:0] (CF1SEL) of the CFMODE[15:0] register.
4
AVARSIGN
0
0: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase A is positive.
1: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase A is negative.
5
BVARSIGN
0
0: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase B is positive.
1: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase B is negative.
6
CVARSIGN
0
0: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase C is positive.
1: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE[7:0] register (total of
fundamental) on Phase C is negative.
7
SUM2SIGN
0
0: if the sum of all phase powers in the CF2 datapath is positive.
1: if the sum of all phase powers in the CF2 datapath is negative. Phase powers in the CF2
datapath are identified by Bits[5:3] (TERMSEL2) of the COMPMODE[15:0] register and by
Bits[5:3] (CF2SEL) of the CFMODE[15:0] register.
8
SUM3SIGN
0
0: if the sum of all phase powers in the CF3 datapath is positive.
1: if the sum of all phase powers in the CF3 datapath is negative. Phase powers in the CF3
datapath are identified by Bits[8:6] (TERMSEL3) of the COMPMODE[15:0] register and by
Bits[8:6] (CF3SEL) of the CFMODE[15:0] register.
