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