Connecting
6.6 Measurement of the armature current
6.6.3.4 Input for +/-1 V at rated armature DC current
This connection option is intended for operation with an LEM transformer.
Connection
XB-1 positive (non inverting), XB-2 negative (inverting). The signal has both polarities
(switches pole during torque changes).
S700 switch positions:
Remove R701.
Parameter settings
p51822 =
p51823 =
p51824 =
Load
The load resistor should be located externally and grounded with the LEM transformer's
power supply. The value should be dimensioned to produce a 1 V voltage at the rated
current.
