206/1 206 A-C Line Voltage Feedback Register
Hex Value:
N/A
Sug. Var. Name:
AC_VRMS% (RMS Volts)
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The A-C Line Voltage Feedback register displays the measured A-C RMS line voltage. A
value of 1 is equal to 1 volt.
207/1207 Current Minor Loop Feedback Register
Hex Value:
N/A
Sug. Var. Name:
CML_FB%
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Current Minor Loop Feedback register displays the measured armature current
(DC Amps) feedback in counts. A value of 4095 is equal to the maximum current limit setting entered
during parameter entry. This register is used as the I-FDBK parameter in the THERMAL OVERLOAD
control block used in DPS drives to monitor the motor for thermal overload.
208/1 208 Armature Current Feedback Register
Hex Value:
N/A
Sug. Var. Name:
ARM-IFB% (Amps x 10)
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Armature Current Feedback register displays the measured armature current (D-C
Amps). The current is measured to within a tenth of an amp. The displayed value is equal to the num-
ber of amps times 10. For example, 50.1 amps would be displayed as 501. If the configured motor
amps value times the overload ratio plus 75% is greater than 3000 amps, then the feedback is dis-
played in amps.
209/1 209 Armature Voltage Feedback Register
Hex Value:
N/A
Sug. Var. Name:

Description:
The Armature Voltage Feedback register displays the measured armature voltage. A
value of 1 is equal to 1 volt.

Description:
The Counter-EMF register displays the measured counter-EMF voltage. A value of 1 is
equal to 1 volt.
