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 in C0011 is always defined as the highest-possible speed.
Example:
A speed of 4500 rpm is to be used in this configuration. The speed is to be corrected in the range from
0 to +10 % via the additional setpoint. A master voltage of 0 to +10 V is available at the inputs X6/1,2
and X6/3,4.
The following parameters are set:
z C0011 = 5000 rpm, C0190 = 1 (addition)
z C0027/1 = 90%
z C0027/2 = 10%
The speed limit can also be influenced by code C0909. Here, you can determine the direction of
rotation:
z C0909 = 0 → CW and CCW rotation allowed
z C0909 = 1 → only CW rotation allowed
z C0909 = 2 → only CCW rotation allowed
In plants where only one direction of rotation is permitted, a reversing of the drive caused by the
setpoint can be avoided.
Additional torque setpoint
In some applications, it may be necessary to add another torque setpoint. Example: adding
acceleration in winding and positioning applications
For this, the input MCTRL-M-ADD is available. In the default setting, this input is not active
(FIXED0%). To use this input, an analog signal source must be assigned.
Torque limitation
The torque can be limited via code C0472/3 from 0 to +100%.
Every other signal source can also be assigned.
Feedback of actual speed
In this configuration, all specified actual value encoders can be used. The corresponding actual value
encoder can be selected under code C0025. An adjustment is not necessary.
Quick stop (QSP)
When the quick stop function is activated, the drive decelerates along the ramp set under C0105 to
zero speed and carries out a holding torque with driftfree standstill. The torque limitation and the
additional torque setpoint have no effect. This means that the drive provides the maximum possible
torque (observe settings of the motor data). When quick stop is reset, the drive synchronizes to the
momentary speed.
Controller inhibit (CINH)
When the controller is inhibited, the drive does not supply a torqueand is coasting. When controller
inhibit is reset, the drive synchronises to the momentary speed.
