Chapter 6 - Parameter Description [EXT][Current]The AM terminal outputs inverter output current. Theoutput value is determined by,AM Output Voltage = (Output current / Rated current) ×10V X AM Output Gain (EXT41~42)/ 150[Voltage]The AM terminal outputs inverter output voltage. Theoutput value is determined by,AM Output Voltage = (Output voltage / Max. outputvoltage) × 10V X AM Output Gain (EXT41~42)/ 100[DC link vtg]The AM terminal outputs the DC link voltage of inverter.The output value is determined by,AM Output Voltage = (DC link voltage / Max. DC linkvoltage) × 10V X AM Output Gain (EXT41~42)/ 100If EXT-53 [Speed Limit Direction]= FWD, EXT-51 [SpeedLimit Bias]FWD Torque control is set, the FWD Torque control isshown as below. In other words, when the motor rotatesin Forward direction, FWD torque is kept controlled inthe range of EXT-50 [Speed Limit Level] + EXT-51[Speed bias]. When the motor rotates in Reversedirection, REV torque is controlled in EXT-51[SpeedLimit Bias] and torque is controlled constant in the abovespeed range. EXT-52 [Speed limit gain] is the curvevalue to reduce the FWD torque or to increase to theconstant torque in Reverse direction.Output torque[Torque]The AM terminal outputs inverter output torque.
