Analog_MaxT_Con
0: Analog_MaxTorque control OFF
1: Max. torque control via AIN1
2: Max. torque control by AIN2
0, 1, 2
For convenience, some new names are used in the formula. Definitions:
AIN1_in: AIN1 input voltage after filter and offset
AIN2_in: AIN2 input voltage after filter and offset
Analog_out: Analog1_out or Analog2_out, depends on wiring and Analog_Speed_Con setting; It’s the result
of AIN real input, filter, offset and deadband.
Final result:
Analog_Speed control ON:
If Analog_out is not limited by Analog_Dead_High or Analog_Dead_Low:
Target speed[rpm]=Analog_out[V]*Analog_Speed_Factor[rpm/V]; otherwise Target speed[rpm]=0.
Analog_MaxTorque control ON:
Max torque[Nm]=Analog_out[V]*Analog_MaxT_Factor[Nm/V]
Example:
Setting: Analog1_Dead=1V, Analog1_Offset=2V, Analog_Speed_Factor=100rpm/V, Analog_Speed_Con=1,
Analog_Dead_High=0V; Analog_Dead_Low=0V;
Where AIN1 input voltage is 5V:
AIN1_in=5V–2V=3V, |AIN1_in| >Analog1_Dead, so Analog1_out=3V–1V=2V;
Target speed=2*100=200rpm.
Where AIN1 input voltage is -5V:
AIN1_in=-5V–2V=-7V, |AIN1_in|>Analog1_Dead, so Analog1_out=-7V+1V=-6V;
Target speed=-6*100=-600rpm.
