Fig. 6-26: Possible control cycle times in accordance with controller
performance and switching frequency that have been set
Note: We distinguish between basic and advanced control.
Advanced control could take place, for example, with
8 kHz/16 kHz switching frequency, 62.5 µs current loop clock,
125 µs velocity loop clock and 250 µs position loop clock.
• Jerk limitation in the "cyclic position control" mode by introducing the
S-0-0349, Jerk limit bipolar parameter. The filter degree of the
smoothing filter (moving average) can be set in parameter P-0-0042,
Current position command average value filter order.
• velocity feedforward to be set, i.e. the feedforward degree can be set
via parameter P-0-0040, Velocity feedforward evaluation
(0 % … 100 %)
• input value for parameter S-0-0348, Acceleration feedforward gain
can directly be the respective inertia in kg*m
2
(for rotary motor) or the
mass in kg (for linear motor)
• Standardization of the output value at the velocity loop to Newton (N)
or Newton meter (Nm). According to the motor type, there are the
following units for parameter S-0-0100 for IndraDrive:
• rotary motor → Nm * s / rad
• linear motor → N * min / mm
• Extending the possibilities for filtering resonance frequencies. There
are 4 filters of 2
nd
degree available that can be set via the parameters
P-0-1120, P-0-1121, P-0-1122 and P-0-1123.
• limiting the acceleration in velocity control by setting in parameter
S-0-0138, Bipolar acceleration limit value
Possibilities of Accessing Outer Control Loops
It is possible to access the outer control loops when operating in a higher-
level mode. Depending on the basic operating mode, the following
parameters are available to do this.
In position control:
• S-0-0037, Additive velocity command value
• S-0-0048, Additive position command value
• S-0-0081, Additive torque/force command value
