General Safety Instructions and Information on Use The specifications and instructions contained in the documentation Warning! must be complied with strictly during installation and commissioning. Only qualified staff who has read the documentation and, in particular, the safety instructions carefully is allowed to carry out installation or commissioning work or to operate the frequency inverters.
Purpose of the Frequency Inverters Warning! The frequency inverters are electrical drive components intended for installation in industrial plants or machines. Commissioning and start of operation is not allowed until it has been verified that the machine meets the requirements of the EC Machinery Directive 98/37/EEC and EN 60204.
Electrical Connection Warning! Before any assembly or connection work, discharge the frequency in- verter. Verify that the frequency inverter is discharged. Do not touch the terminals because the capacitors may still be charged. Comply with the information given in the operating instructions and on the frequency inverter label.
System description Positioning via motion blocks enables movement by a certain distance or to a target position. For each motion block, a separate motion profile can be set, including speed, acceleration and deceleration ramp. When motion blocks are processed au- tomatically, the drive will react according to the parameterized behavior when it reaches the target position.

Digital signals for status indication Digital signals can be influenced depending on the status of a motion order. For example, a digital signal can be parameterized such that it signals reaching of the target position or the end of the motion block. JOG mode The drive is operated manually via two digital inputs at a parameterizable, fixed speed.
3.5.1 Getting started In order to use the positioning function, you must start the frequency inverter in Configuration 240, 440 or 540. If required, perform a motor measurement. Several functions will be readjusted as soon as you set up the configuration of the position- ing operation.
3.5.1.2 Two different encoders for motor and positioning In systems where slip may occur, the motor encoder cannot be used as position encoder at the same time. Due to the slip (e.g. slipping in the case of a wheel/rail system), the motor encoder cannot approach the actual target with sufficient accu- racy.
3.5.1.3 No motor encoder, external encoder for positioning In some applications the speed control accuracy and the dynamic behaviour of a sensorless motor control are sufficient. Positioning is possible in non-slip and in slip- containing systems via an external encoder. Configuration 30 = 440, only position encoder Encoder 1...
3.5.2 Reference system The reference system provides the link between the electrical system and the me- Feed Constant chanical system. In parameter 1115, the user units (u) per revolution (U) are entered. By choosing a suitable parameter configuration, the feed constant can consider both the mechanical motion distance and the accuracy (resolution) (see example).

Operation Modes of the Positioning General Issues about Operation Modes The following operation modes are available for positioning. Operation modes: − Positioning mode. Automatic operation for sequence-controlled and repeatable approach to different targets in an application. The target can be selected via an overriding controller (parameter channel of field bus or digital inputs).
4.1.1 Assignment of digital inputs In the individual operation modes of the positioning, the digital inputs have different inputs. The following table provides an overview of the functions and assigns them to the terminals, as parameterized in the factory settings for the functions.

4.1.1.1 Instructions on MFI1D (multifunction input) Multi-function input MFI1D is processed, depending on the application or function, as an analog input value or a digital input signal. By default, the positioning function uses multi-function input MFI1D as a digital signal for certain functions. The sampling rate of multi-function input MFI1D is slower than that of digital signals S1IND, S2IND, etc.

4.2.4 Home offset Home Offset With parameter 1131, the point of reference for positioning can be adjusted to the mechanical system. Home Offset The value adjusted for parameter 1131 is added to the home position. Positive values will cause a shift of the point of reference in positive direction (clockwise), negative values will cause a shift in negative direction (anticlockwise).
Acceleration Via parameter 1134, the acceleration and deceleration value to be used for homing is adjusted. Ramp Rise Time Parameter 1135 defines the time in which the frequency is to be brought to the acceleration and deceleration ramp adjusted for homing. In this way, a non-linear acceleration and deceleration (S-curve) can be obtained for homing, and the load during acceleration and deceleration of the drive can be reduced, e.g.
Attention! − After changing motion profiles, you should test the automatic se- quence of motion blocks at reduced speed. The scaled speed func- Speed Override tion can be activated via parameter 1236. For the test, an emergency stop device must be provided in order to be able to stop the drive immediately in the case of extraordinary move- ments.
Positioning Mode And Motion Block Data 4.4.1 Motion Mode The positions are defined either in relation to a fixed reference position (absolute motion mode), in relation to other positions or a touch-probe sensor. Parameter Motion Mode 1208 enables the selection. Motion Mode = 0 - absolute 1208...

4.12 Position Controller The position controller evaluates the positioning operation (target/actual position) and tries to control the drive such that it comes as close as possible to the specifica- tions. For this purpose, an additional frequency is calculated for compensation of position deviations.
Page 113
In order to avoid oscillations of the drive while it is at standstill, amplification is re- duced to 50 % of the parameterized value for small position deviations Amplification [%] Control deviation -0.25 0.00 0.25 0.50 -0.50 of position [°] The following behavior may indicate that the controller parameters are not config- ured properly: −...
4.13 Store the actual position value (latching function) With the latching function the actual position value of the drive can be stored. With a rising or falling signal edge at digital input S2IND the actual position value is Latched Position stored in the EEPROM and displayed via 1281.

In configuration 240 S4IND (X210A.6) and S5IND (X210A.7) are parameterized by default as inputs for Encoder 1. Via S6IND (X210B.1), the zero track of a HTL en- coder can be evaluated. Alternatively, the inputs of an optional extension module EM- ENC can be used as encoder inputs.
List of homing modes In the following sections, the homing modes are explained in detail. The sections are organized as follows: • 5.1 Brief description 5.2 Overview table • • 5.3 Graphical overview 5.5 Detailed explanations • The graphic overview and overview table are recommended for experienced users who are already familiar with the functions of the different homing types.

When coming from the right, direction is reversed when passing the edge.
Terminology To enable a better understanding of the homing modes, the terms used are ex- plained in the following. Home switch active = 1 "High" signal is present inactive = 0 "Low" signal is present not used In this homing mode, no home switch is used Travel limit.
In some cases, this also causes a speed change. If the other (non-selected) limit switch is actuated, the corresponding error message is triggered). BONFIGLIOLI VECTRON recommends that wire break proof limit Note: switches be used ("0 - active").
