Limitation of the speed setpoint
The speed setpoint is always limited to 100% n
max
(C0011) in the MCTRL function block. This means
that the maximum speed is always specified to the greatest speed possible in C0011.
Example:
With this configuration a speed of 4500 rpm is to be travelled. The speed is to be corrected in the
range from 0 to +10% using the additional setpoint. At inputs X6/1,2 and X6/3,4 a master voltage of
0 to +10 V is provided.
The following parameter setting results from this:
l C0011 = 5000 rpm, C0190 = 1 (addition)
l C0027/1 = 90%
l C0027/2 = 10%
Code C0909 presents another possibility of influencing the speed limit. Here the direction of rotation
can be specified:
l C0909 = 0
³ clockwise and counter−clockwise rotating direction permitted
l C0909 = 1
³ only clockwise rotating direction permitted
l C0909 = 2
³ only counter−clockwise rotating direction permitted
For systems that only permit one rotating direction this serves to prevent the drive from rotating
backwards which would be caused by the setpoint.
Additional torque setpoint
For some applications it may be required to apply an additional torque setpoint.
Example: An acceleration connection for winding and positioning applications:
For this purpose, the input MCTRL−M−ADD is provided. This input is not active by default (is on
FIXED0%). To use this input, an analog signal source has to be assigned to it.
Torque limitation
The torque can be limited in the range from 0 to +100% via code C0472/3.
Every other signal source can be assigned as well.
Actual speed value feedback
In this configuration all specified actual value encoders can be used. The corresponding actual value
encoder can be selected via code C0025. An adjustment is not required.
