Signal limitation
ƒ If the drive operates with the maximum torque, the speed controller operates
within the limitation.
ƒ The drive cannot follow the speed setpoint.
ƒ The output SPEED−MCTRL.MMax is set to TRUE.
ƒ The output TORQUE−MCTRL.MMax is set to TRUE.
Set the I component
For selecting torque starting values the integral component of the speed controller can be
set externally (e.g. when using the brake control).
ƒ In case of speed control ("Speed"):
SPEED−MCTRL.ILoad = TRUE (C7411/12):
– The speed controller accepts the value applied at SPEED−MCTRL.ISet (C7431/8) into
its integral component.
– The value at SPEED−MCTRL.ISet (C7431/8) acts as a torque setpoint for the motor
control.
SPEED−MCTRL.ILoad = FALSE (C7411/12):
– The function is switched off.
ƒ In case of torque control ("Torque"):
TORQUE−MCTRL.ILoad = TRUE (C7511/7):
– The speed controller accepts the value applied at TORQUE−MCTRL.ISet (C7531/8)
into its integral component.
– The value at TORQUE−MCTRL.ISet (C7431/8) acts as a torque setpoint for the motor
control.
TORQUE−MCTRL.ILoad = FALSE (C7511/7):
– The function is switched off.
