Position Loop<br />

Velocity Loop<br />

DOK-INDRV*-FU*********-IB01-EN-P<br />

• P-0-0556, Config word of axis controller (bits 2 and 5)<br />

With <strong>Indra<strong>Drive</strong></strong> and ADVANCED control sections (and firmware) the<br />

following cycle and switching times can be obtained:<br />

• PWM switching frequency max. 16 kHz<br />

• current loop clock TA_current = 62.5 µs<br />

• velocity loop clock TA_velocity = 125 µs<br />

• position loop clock TA_position = 250 µs<br />

With <strong>Indra<strong>Drive</strong></strong> and BASIC control sections (and firmware) the following<br />

cycle and switching times can be obtained:<br />

• PWM switching frequency max. 8 kHz<br />

• current loop clock TA_current = 125 µs<br />

• velocity loop clock TA_velocity = 250 µs<br />

• position loop clock TA_position = 500 µs<br />

Note: All data on performance are contained in section "Overview of<br />

Functions: Performance Data" in chapter "System Overview".<br />

• Jerk limitation in the "cyclic position control" mode by introducing the<br />

S-0-0349, Jerk limit bipolar parameter. The filter degree of the<br />

smoothing filter (moving average) can be set in parameter P-0-0042,<br />

Current position command average value filter order.<br />

• velocity feedforward to be set, i.e. the feedforward degree can be set<br />

via parameter P-0-0040, Velocity feedforward evaluation<br />

(0 % … 100 %)<br />

• input value for parameter S-0-0348, Acceleration feedforward gain<br />

can be the respective inertia in kg*m^2 (for rotary motor) or the mass<br />

in kg (for linear motor)<br />

• Standardization of the output value at the velocity loop to Newton (N)<br />

or Newton meter (Nm). According to the motor type, there are the<br />

following units for parameter S-0-0100 for <strong>Indra<strong>Drive</strong></strong>:<br />

• rotary motor → Nm * s/rad<br />

• linear motor → N * min/mm<br />

• Extending the possibilities for filtering resonance frequencies. There<br />

are 4 filters of 2 nd degree available that can be set via the parameters<br />

P-0-1120, P-0-1121, P-0-1122 and P-0-1123.<br />

• limiting the acceleration in velocity control by setting in parameter<br />

S-0-0138, Bipolar acceleration limit value<br />

Possibilities of Accessing Outer Control Loops<br />

It is possible to access the outer control loops when operating in a higherlevel<br />

mode. Depending on the basic operating mode, the following<br />

parameters are available to do this.<br />

In position control:<br />

• P-0-0059, Additive position command value, controller<br />

• S-0-0037, Additive velocity command value<br />

• S-0-0081, Additive torque/force command value<br />

In velocity control:<br />

• S-0-0037, Additive velocity command value
