Unit Description / Notes
When parameters P237 = 2 and P241 = 2, the torque current limit (P169
and P170) is given by the signal at the Analog Input AI2.
When parameters P237 = 2 and P241 = 4, the torque current limit (P169
and P170) is given by the sum of the signals at Analog Inputs AI2 and
AI3.
When parameters P237 = 4 and P241 = 4, the torque current limit (P169
and P170) is given by the sum of the signals at Analog Inputs AI1 and
AI2.
Note: The range of the sum between AI2 and AI3 may vary from 0 to
180 %. If the sum result is negative, then the value will be set to zero.

When a current signal is used at the Analog Input AI3, set the S4.1
switch on the EBB board to "ON".
Options 2 and 3 provide an inverse reference with which is possible to
have maximum speed with minimum reference.
