Current Shunt Variables
Input variables : IA_SHUNT and IB_SHUNT can configure the current inputs to accept shunt resistor sensors. In this case the
CE provides an additional gain of 8 to the current inputs. This will enable the pulse rate to change by 8 times. In order to
maintain a normal pulse rate WRATE may have to be decreased by 8 times. Whenever IA_SHUNT or IB_SHUNT are set to 1 or
a positive number, In_8 is assigned a value of 8 in the equation for Kh.

When +1, these variables increase the respective current gain by 8. The
gain factor controlled by In_SHUNT is referred to as In_8 throughout this
document. Allowed values are 1 or –1. For example, if IB_SHUNT =-1, IB_8

CAL should be scaled by 1/(1 – 0.01).
