Analog Tach
242 Arm Volts Spd FB
Displays speed feedback from armature voltage. Select
analog tach by entering a value of 6 in of parameter 222
[Motor Fdbk Sel]. Armature Voltage Feedback is calculated
using parameter 2137[Arm Volt FB Cnts] parameter 2151 [Arm
Resistance], and parameter 2127 [CML Feedback]. Units:
