ƒ The signal at input MCTRL−N−SET is the speed setpoint in [%] and
always refers to the maximum speed (C0011).
ƒ In the most basic configurations, MCTRL−N−SET is connected with the
function block NSET (speed setpoint conditioning).
– It is also possible to connect MCTRL−N−SET with any other analog
output signal of an FB.
ƒ The speed setpoint at MCTRL−N−SET is always limited to ±100 % of the
maximum speed n
max
(C0011).
ƒ The speed setpoint is converted into a frequency setpoint by the motor
control and is limited to a maximum output frequency depending on
the chopper frequency f
