Select the source to switch between acceleration/
deceleration ramp pairs 1 and 2.
0 = Acceleration time 1/Deceleration time 1 are in
force, 1 = Acceleration time 2/Deceleration time 2
are in force. 22.01 Acc/Dec sel
Torque reference set-up
Select the source of the torque reference signal. 24.01 Torq ref1 sel
Define the maximum and minimum torque
references. 24.03 Maximum torq ref
