13.20.7 Torque control with speed limitation
Set MCTRL_bNMSwt_b = TRUE, in order to activate this function.
ƒ For the speed limitation a second speed controller (auxiliary speed controller) is
connected.
ƒ MCTRL_nMAdd_a acts as a bipolar torque setpoint.
ƒ The speed controller 1 is used to make up the upper speed limit.
– The upper speed limit is specified by MCTRL_nNSet_a in [%] of n
max
(positive sign
for clockwise sense of rotation).
ƒ The speed controller 2 (auxiliary speed controller) is used to make up the lower
speed limit.
– The lower speed limit is specified by MCTRL_nNStartLim_a in [%] of n
max
(negative
sign for anticlockwise sense of rotation).
ƒ N
max
is selected via C0011. ( ¶ 357)
