2.1 Installation

2.1.1 Safety notes

WARNING

High Voltages up to 900V!

Risk of electric shock. Residual charges in the capacitors can still have dangerous levels several minutes after switching off the supply voltage. Power and control connections can still be live, even though the motor is not rotating.

Install and wire up the equipment only while it is not electrically con

nected. Make sure that the control cabinet is safely isolated (lock-out, warning signs etc.).The individual supply voltages will not be switched on until setup is carried out.

Measure the voltage in the intermediate (DC-link) circuit and wait until it

has fallen below 50V.

CAUTION

Automatic Start!

Risk of death or serious injury for humans working in the machine. Drives with servo amplifiers in fieldbus systems are remote-controlled machines They can start to move at any time without previous warning.

Implement appropriate protective measures to ensure that any unintended start-up of the machines cannot result in dangerous situations for personnel or machinery.

The user is responsible for ensuring that, in the event of a failure of the servo amplifier, the drive is set to a state that is functional safe, for in stance with the aid of a safe mechanical brake.

Software limit-switches are not a substitute for the hardware limit-switches in the machine.

Install the servo amplifier as described in the instructions manual. The wiring for the analog setpoint input and the positioning interface is not required.

Because of the internal representation of the position-control parameters, the position controller can only be operated if the final limit speed of the drive does not exceed: rotatory at sinusoidal² commutation: 7500 rpm at trapezoidal commutation: 12000 rpm. linear at sinusoidal² commutation: 4 m/s at trapezoidal commutation: 6.25 m/s

All the data on resolution, step size, positioning accuracy etc. refer to calculatory values. Non-linearities in the mechanism (backlash, flexing, etc.) are not taken into account. If the final limit speed of the motor has to be altered, then all the parameters that were previously entered for position control and motion blocks must be adapted.

2.1.2 Inserting the expansion card (S300, S600 and S700)

The expansion card for S300/S700 is different from the card for S600. The text "PROFIBUS DP" on the front label marks the card for S300/S700, the text "PROFIBUS" the card for S600.

To fit the PROFIBUS expansion card into the servo amplifier, proceed as follows:

Remove the cover of the option slot (see installation manual of the servo amplifier.)

Take care that no small items (such as screws) fall into the open option slot.

Push the expansion card carefully into the guide rails that are provided, without twisting it.

Press the expansion card firmly into the slot, until the front cover touches the fixing lugs. This ensures that the connectors make good contact.

Use the screws on the expansion card to secure it in the drive.

2.1.2.1 Front view

Shown is the expansion card for S300/S700.

2.1.2.2 Setup of Station Address and Baud Rate

During setup it makes sense to use the keypad on the front panel to preset the station addresses for the individual amplifiers (see chapter "Setup" in the instructions manual).

After changing the station address you must turn the 24V auxiliary supply for the servo amplifier off and on again for the new address to take affect.

Possible ways for setup:

keypad on the front panel of the servo amplifier (see instructions manual)

setup software: screen page “CAN / Fieldbus” (see online help)

serial interface with a sequence of ASCII commands: ADDR nn Þ SAVE Þ COLDSTART (with nn = address)

The Baudrate is defined by the hardware configuration in the master controller. Baudrates up to 12 MBaud are possible. During bus initialization, the master controller sends the amplifier the desired baud rate.

2.1.2.3 Connection technology

Cable selection, cable routing, shielding, bus connector, bus termination and transmission times are all described in the “Installation guidelines for PROFIBUS-DP/” from PNO, the PROFIBUS User Organization.

2.1.3 Profibus master module setup

2.1.3.1 Configuration of the master controller ( e.g. Siemens S7)

The graphics interface makes it very easy to configure the Siemens S7 for the PROFIBUS network. After you have set up the control layout, configure the interface module that is used as follows: Use our library file KOLL045D.GSD to configure the Profibus master for the servo amplifier. The follow ing shows a Siemens PLC. Other machine controllers can also be configured for the Kollmorgen Profibus expansion card. Open the Hardware catalog and drag the symbol for the corresponding field unit onto the representation of the bus system. A window opens auto- matically for the general parameterization of the field unit (please observe: the S300/S700 are displayed here like a S600). Enter the address of the participant here.

Next, use the same method as above to drag the module from the Hardware catalog into the box for the field unit, whereby the 4-word module must lie in Cell 0 and the 6-word module in Cell 1.

Another window opens, in which you can set the parameters for the module.

2.1.4 Standard function block for date exchange with the servo amplifier

Kollmorgen supplies a S7-function block (FB10) for use Siemens PLC that make it possible to han dle the servo amplifier control functions very simply. This function block and its description can be found as a text file on the CDROM and in the down load section of our website.

2.2 Amplifier setup

2.2.1 Guide to setup

Only properly qualified personnel with professional expertise in control and drive technology are permitted to setup the servo amplifier.

Check assembly

+ installation

Connect PC,

start setup software

CAUTION: Automatic Start!

Risk of death or serious injury for humans working in the machine. The drive performing unplanned movements during commissioning cannot be ruled out. Make sure that, even if the drive starts to move unintentionally, no danger can result for personnel or machinery. The measures you must take in this regard for your task are based on the risk assessment of the application.

Check that all the safety instructions, which are included in both the instructions manual for the servo amplifier and in this manual, have been observed and implemented.

Use the setup software for setting the parameters for the servo am plifier.

Setup the

basic functions

Save

parameters

Test the

bus connection

Now setup the basic functions of the servo amplifier including tuning the servo loops. This part of setup is described in the online help system of the setup software.

When the optimization is finished, save the controller parameters in the servo amplifier.

Remove the Enable signal (Terminal X3) and switch off the mains power supply for the servo amplifier. The 24V DC auxiliary voltage remains switched on. Test the installation of the PROFIBUS connection and the interface to the PROFIBUS master. Check the PROFIBUS-DP parameter settings and the station con figuration. Check the parameter settings for the PROFIBUS interface module. Check the PLC user program and the parameter settings for the function block.

2.2.2 Important amplifier configuration parameters

The following parameters configure the amplifier for the Profibus interface. They can be set using the setup software for the amplifier.

EXTWD (PNU 1658)

With this parameter, the observation time (watch dog) for the fieldbus-slot communication can be set. The observation is only active, if a value higher than 0 is assigned to EXTWD (EXTWD=0, observation switched off) and the output stage is enabled. If the set time runs out, without the watchdog-timer being newly triggered by the arrival of a telegram, then the warning n04 (response monitoring) is generated and the drive is stopped. The amplifier remains ready for operation and the output stage enabled. Before a new driving command (setpoint) is accepted, this warning must be deleted (function CLRFAULT or INxMODE=14).

ADDR (PNU 918)

With this command, the node address of the amplifier is set. When the address has been changed, all parameters should be saved to the EEPROM and the amplifier switched off and on again.

Since the modular structure of the S400 as a multi-axis system requires its own addressing, there is the additional parameter ADDRFB (PNU 2012) for this series, with which a field bus address differ ent from the internal device address (ADDR) can be defined. As long as ADDRFB = 0, ADDR is the bus address. If ADDRFB > 0, then ADDRFB is the bus address. ADDR is set automatically by the S400 master module in descending order.

AENA (PNU 1606)

With this parameter, the state of the software-enable after switch-on can be defined. The software-enable allows an external control to enable/disable the output stage. For amplifiers with analog setpoints (OPMODE=1,3) the software-enable is set automatically after switch-on and the devices are ready for operation immediately (if hardware-enable is present). For all others, software-enable will be set to the value of AENA. The variable AENA also has functionality when resetting the amplifier after an error (by digital input 1 or the CLRFAULT command). If an error can be reset by the software, the software-enable is set to the value of AENA after the error is cleared. In this way the behavior of the amplifier after a software-reset is similar to after the drive is switched on.

INPT, INPT0 (PNU 1904)

With INPT (S300/S700: INPT0) a delay for the in-position message can be set. With the start of a motion task the in-position message is deleted and the monitoring of the position is activated after expiration of the adjusted time. This function is particularly important for positioning procedures within the in-position window. In this case the in-position message is delayed for a defined time.

The PROFIBUS profile PROFIDRIVE includes the following parameter process-data objects (PPO):

The servo amplifier only uses the PPO-type 2 (with 4 words PKW-section and 6 words PZD-section). The PKW-section is used mainly for the transmission of parameters for the servo amplifier, the PZD-section is used principally for handling motion functions.

The telegram can be divided into two sections or data channels:

1. PKW-section (4 words, Bytes 1 to 8)

2. PZD-section (6 words, Bytes 8 to 20)

The PKW data channel can also be termed the service or parameter channel. The service channel only uses confirmed communication services, and is used by the servo amplifier as a parameter channel.

The PKW channel has no real-time capability.

The PZD data channel can also be termed the process data channel. The process data channel uses unconfirmed communication services. The response of the servo amplifier to an unconfirmed service can only be seen in the reaction of the amplifier (status word, actual values).

The PZD channel has real-time capability.

3.1.3 Parameter value PWE

The data for the PNU-variable is contained in the PWE, and is placed flush right (PKE):

4-byte data (double-word) PWE 5-8 (PWE 8 LSB)

Commands are transferred right justified with task ID 3. If a command cannot be executed, the response identification AK = 7 signals the error, and an error number is given out. The error num bers are described on page 19.

3.2 The process data channel (PZD)

Cyclical data are exchanged across the PROFIBUS through the process data section of the 20-byte telegram. Each PROFIBUS cycle triggers an interrupt in the servo amplifier and new process data is exchanged and processed. The interpretation of the PZD by the amplifier depends on the operating mode that is set. The operating mode is set through a PROFIBUS parameter (PNU 930,

ð p. 25).

In all operating modes, data word 1 of the process data (PZD1) in the direction from control system to servo amplifier is used for instrument control, and in the direction from servo amplifier to control system it has the function of a status indicator for the amplifier.

The interpretation of the process data PZD2 – PZD6 changes depending on the operating mode, as can be seen in Chapter 5.2.

When the servo amplifier is switched on, the PROFIDRIVE operating mode that is always set to –126 (safe state). Before changing the operating mode, bit 10 of the control word STW must always be set to 0. The new operating mode only becomes active when bit 10 of the control word is set to 1 (see p. 25).

The digital servo amplifiers of the servo amplifier series have to be adapted to the circumstances of your machine. The parameters for the controllers are set using either the setup software or via the PROFIBUS.

4.1 Read/write an amplifier parameter

Read (AK = 1) or write (AK = 3) amplifier parameters

To read or write an amplifier parameter through PROFIBUS, the corresponding PNU must be used. The parameters that are written to the servo amplifier can be transferred to the non-volatile memory by using the command “non-volatile parameter save” (PNU 971).

Telegram layout:

Request Response

PKE/AK 1 (read) / 3 (write) 2 (OK) / 7 (error) PKE/PNU see 4.2.1 as transmitted

for AK = 3 see p.22ff for data type for AK = 1 data type irrelevant

4.2 Summary of the parameter numbers

for AK = 3 returns the PWE of the request for AK = 1 see p.22f for data type

All the parameter numbers (PNUs) for the servo amplifier are listed in numerical order in the table on page 22ff, with a short description. The parameter numbers in the range 900 – 999 are profile-specific for the PROFIBUS drive profile PROFIDRIVE. Parameter numbers > 999 are manufacturer- specific.

For better understanding, you can look up the ASCII commands which are in the column “ASCII command” in the online help the setup software. A description of all ASCII commands can be found in the ASCII reference lists (referring to the servo amplifier type) located on the product CDROM and on our website.

Parameter numbers >1600 use the object channel (see p.33ff).

In the S400/S600 some amplifier parameters (e.g. GV) have 2 PNU numbers. Both of them can be

used to read and write the parameter (e.g. PNU 1200 and PNU 1672).

4.2.2.1 PNU 940/911: PPO type write/read

These parameters describe the numbers of the supported PPO-types write und read. Since only PPO-type 2 is supported (see Chapter 3), this parameter is always set to 2.

4.2.2.2 PNU 918: PROFIBUS node address

With this parameter the PROFIBUS - node address of the amplifier can be read.

S400/S600

The range of addresses can be extended from 1..63 to 1..127 with the ASCII-command MDRV.

Setting up the station address, see page 10.

4.2.2.3 PNU 963: baud rate

This parameter defines the index of the baud rate that is used for PROFIBUS communication, and can only be read. The baud rate is given out by the PROFIBUS-master. The table below shows the indices with the according baud rates (in kBaud):

This parameter can be used to read out the number of the PROFIDRIVE profile. Profile Number 3, Version 2 is used.

4.2.2.5 PNU 970: default parameters

With this parameter you can reject all the parameters that are set and load the manufacturer’s default values.

4.2.2.6 PNU 971: non volatile saving of parameters

With this parameter you can save all the parameter settings to the EEPROM. To do this, the param eter must have the value PWE = 1 when the transfer takes place.

Operating mode servo amplifier

(ASCII command “OPMODE”)

Description

The individual operating modes are described in chapter 5.2. A change of operating mode can only be undertaken in connection with the control word.

The operating mode must be changed according to the following sequence:

1. Inhibit setpoints and process data Bit 10 in the control word is set to 0, so that no new setpoints will be accepted by the servo amplifier and no new control functions can be initiated. A new operating mode can, however, be selected while a motion function is being performed. The control word is only inhibited to the extent that the servo amplifier can always be switched into a safe state.

2. Select the new operating mode with PNU 930 The new operating mode is selected with parameter 930 through the parameter channel, but not yet accepted.

3. Set/receive the setpoints and actual values Enter the corresponding setpoints in the setpoint area of the process data. Here you must take note that the normalization and data formats depend on the operating mode that is selected. The interpretation of the actual values is also altered (see Þ p. 17 and p. 39ff). The user program must respond accordingly.

4. Enable the setpoints Bit 10 of STW is set to 1. The setpoints are immediately accepted and processed. The new actual values are output with the appropriate normalization and data format.

After switch-on or after a coldstart the servo amplifier is always in the safe operating mode. In the safe operating mode (-126), no motion functions can be initiated via the PROFIBUS. However, it is possible to perform motion functions with the the setup Software. If the operating mode is changed, then motion functions can only be operated via the PROFIBUS. If the operating mode is changed via another communication channel, then the amplifier is emergency braked and the error F21 (Handling error, expansion card) is signaled.

27-30 Error F28 - F31*: reserved

31 Error F32*: System error

When the cause of the error has been cleared, the error state can be canceled by setting Bit 7 in the control word (STW). The error response of the servo amplifier to the reset will differ, depending on the error that has occurred: For errors that are marked by an asterisk (*), setting the reset bit initiates a cold-start of the ampli

fier, whereby the PROFIBUS communication to this amplifier will also be interrupted for several sec onds. Depending on the circumstances, this break in communication may have to be separately handled by the PLC. For the other errors, the reset leads to a warm start, during which the communication will not be interrupted.

A description of the individual errors and recommendations for removing them can be found in the amplifier's installation manual.

4.2.5.1 PNU 1790: position

Since the servo amplifier calculates all positioning operations internally only on an incremental basis, there are limitations on the usable range of values for distances that are given in SI (user) units. The range for the incremental position covers the values from -2 The resolution that is determined by the PGEARO (PNU1803 ind1) and PGEARI (PNU1802 ind1) parameters and the variable PRBASE fix the sensibly usable range for positioning operations. The variable PRBASE determines, through the equation motor turn. The value of PRBASE can only be 16 or 20. PGEARO contains the number of increments that must be traversed when the distance to be moved is PGEARI. The default values for PGEARO correspond to one turn. The number of turns that can be covered are given as follows:

-2048..+2047 for PRBASE=16 and -32768..+32767 for PRBASE=20 The sensibly usable position range is derived as follows:

4.2.5.3 PNU 1785: motion task type

Bit Value Meaning

The position value that is given is evaluated as an absolute position.

9 10 11

15 -

The position value that is given is evaluated as a relative traversing distance.

The two following bits then determine the type of relative motion. If Bit 1and Bit 2 are set to 0 and Bit 0 set to 1, then the relative motion task is performed

according to the “InPosition” bit. The new target position is given by the old target position plus the traversing distance.

Bit 1 has priority over Bit 2. If Bit 1and Bit 2 are set to 0 and Bit 0 set to 1, then the relative motion task is performed

according to the “InPosition” bit. The new target position is given by the actual position plus the traversing distance.

no following task available

There is a following task, but it must be defined through parameter O_FN, PNU 1788

Change over to next motion task, with braking to 0 at the target position.

Change over to next motion task, without standstill at the target position.

The type of velocity transition is determined by Bit 8. Change over to next motion task, without evaluating inputs.

A following motion task is started by a correspondingly configured input.

Start the next motion task by Input State = low or if bit 7 = 1after the delay set in

PNU 1789. Start the next motion task by Input State = high or if bit 7 = 1after the delay set in

PNU 1789. The next motion task is started immediately.

The next motion task is started after the delay time set by PNU 1789 or, if Bit6=1,previ

ously by a corresponding input signal. Only for following motion tasks and Bit4=1:from the target position for the previous mo-

tion task onwards, the velocity is altered to the value for the following motion task. The change of velocity is made so that the velocity at the target position of the previous

motion task matches the value given for the following motion task.

reserved

Accelerations are calculated according to the run-up/acceleration and run-down/braking

times for the motion task. the deceleration/aceleration ramps are interpreted in mm/s²

The target position and target velocity of a motion task are interpreted as increments.

The target position and target velocity are recalculated as increments before the start of

the motion task. The parameters PGEARI and PGEARO are used for this purpose. The programmed velocity is used as the velocity for the motion task.

The velocity for the motion task is determined by the voltage present on analog input 1at

the start of the motion task. reserved S300/S700 only: a motion task with trapezoid profile is started

S300/S700 only: a table motion task (sin

profile) is started. Bit 9 must be set to 0.

Bits 0 to 15 are transmitted as motion task type in PZD 6 (mode "positioning") with direct motion tasks.

Bit 16 is not affected by the motion task type transmitted with the process data in PZD 6 and there

fore must be written with PNU 1785 to the parameter channel.

5 Process data channel

The process data channel is used for real-time communication. This channel is divided into two tele gram sections:

PZD1: Control word (STW) /Status word (ZSW) – instrument control

The control word and the status word are used to control the amplifier and monitor the amplifier's status.

PZD2-6: Setpoint / actual values depending on the operating mode.

Setpoints and actual values such as position, velocity and current are exchanged in this section.

The availability of a process data channel is determined in the PROFIDRIVE drive profile. The data that can be transferred is defined according to the operating mode (see “Setting the operating mode s” chapter 4.2.2.7). The process data that are used are determined in such a way that the real-time capability of this channel is optimally used. In this chapter the instrument control is described first, and then the functions and details of each operating mode .

Output stage is switched on (enabled), motion functions are enabled. If an amplifier error occurs, the servo amplifier changes to the amplifier state “Error response active”. In this state, the power stage is switched off immediately. After this error response has taken place, it changes to the state “Error”. This state can only be terminated by the bit-command “Error-reset”. To do this, the cause of the error must have been removed (see ASCII command ERRCODE).

Speed setpoint for a direct motion task

The usable range for the speed is not limited by the available data area. It is limited by the maximum achievable speed nmax, which is given by the speed parameter VLIM as the final limit speed for the motor. Maximum speed is derived from the following formula:

Position setpoint for a direct motion task

The servo amplifier calculates all position values internally on an incremental basis only, so there are limitations on the usable range of values for distances that are given in SI (user) units. The range for the incremental position covers the values from -2

to (231-1). The resolution that is determined by the PGEARO (PNU1803) and PGEARI (PNU1802) parameters and the variable PRBASE fix the usable range for position values. The variable PRBASE determines, through the equation

PRBASE

= 2

, the number of increments per motor turn. The value of PRBASE can only be 16 or 20. PGEARO contains the number of increments that must be traversed when the distance to be moved is PGEARI. The default values for PGEARO are 1048576 (PRBASE = 20) or 65536 (PRBASE = 16) and correspond to one turn. Number of turns that can be covered :

-2048..+2047 for PRBASE=16 and -32768..+32767 for PRBASE=20 The sensibly usable position range is derived as follows:

Direction PZD 1 PZD 2 PZD 3 PZD 4 PZD 5 PZD 6

Controller to Amplifier STW 10 bytes of ASCII-data Amplifier to Controller ZSW 10 bytes of ASCII-data

The operating mode “ASCII-channel” is used for parameterizing the servo amplifier.

With this channel, just as with any terminal program, ASCII data can be exchanged with the servo amplifier via the RS232 interface. The control of the communication is performed by handshake bits in the control and status words. The assignment is as follows:

Bit 12:

Bit 13:

Control word

Any transition edge on this bit informs the servo amplifier that valid ASCII data are available in its process data input section, i.e. that with effect from this moment valid data must have been entered into the PZD transmission section PZD 2 - PZD 6 by the control system.

Status word

The servo amplifier confirms that it has accepted the ASCII data, by a transition edge on this bit.

Status word

The servo amplifier uses a “1” in this bit to signal that the ASCII buffer now contains valid data. A transition edge of Bit 14 in the control word STW can be used to make the servo amplifier write the buffer contents to the PZD reception section of the bus-master.

, group "Servo pump".

Bit 14:

Control word

Any transition edge on this bit requests the servo amplifier to write the contents of its filled ASCII buffer to the receive process data of the bus master

Status word

The servo amplifier uses a transition edge on this bit to signal that the ASCII buffer data have been written to the process data.

When transmitting ASCII data, you must observe:

1. Every ASCII command must be terminated by the “CR LF” character sequence.

2. If the ASCII command (with CR LF) is shorter than the 10 characters that are available, then the rest of the telegram must be filled up with bytes with a content 0x00.

3. ASCII commands that are longer than 10 characters must be divided into more than one telegram, whereby a maximum of 30 characters can be sent before the buffer must be read out once.

PROFIBUS for S300/S400/S600/S700 43

Page 44

Process data channel 04/2017 Kollmorgen

When evaluating the responses to the transmitted ASCII command, you must observe:

1. The ASCII response is always terminated by an “End of Text” (EOT = 0x04) character.

2. Response telegrams can include less than 10 bytes of user data, without the response being concluded. The telegram must then be filled up with bytes with the value 0x00.

3. After reading out the buffer, Bit 13 of the status word is reset to “0”, until the buffer is filled again. The designation of the end of the ASCII response is in all cases “End of Text”.

5.2.10 Operating mode after switch-on (operating mode -126)

In this state, it is possible to control the state machine, but motion functions cannot be initiated (see page 25).

6.1 Example telegrams

All examples are valid for all servo amplifiers.

6.1.1 Zero telegram (for initialization)

At the beginning of PROFIBUS communication via the parameter channel and after communication errors, a zero telegram should be sent:

Byte 1 2345678

0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000

PKE IND PWE

The servo amplifier answers, by likewise setting the first 8 byte of the telegram (PKW) to zero.

6.1.2 Setting the Opmode

After switch-on or a reset (coldstart) the servo amplifier is in the PROFIBUS operating mode -126, in which it cannot perform any motion functions. For example to carry out positioning operations (motion tasks, jogging, homing), it must be set to the position-control mode. The procedure to do this is as follows:

a) Set the control word Bit 10 (PZD1, Bit 10) to 0.

This invalidates the process data for the servo amplifier.

Byte 9 10 11 12

xxxx x0xx xxxx xxxx xxxx xxxx xxxx xxxx

STW HSW

b) Transmit PNU 930 through the parameter channel to set the operating mode.

Byte 1 2345678

0011 0011 1010 0010 xxxx xxxx xxxx xxxx 0000 0000 0000 0000 0000 0000 0000 0010

PKE IND PWE

The bits in the PKE section of the PKW have the following significance:

Bit 0 to 10 = PNU 930, Bit 12 to 15 = AK 3 (see also Chapter 3.1.1)

The servo amplifier sends a response telegram with AK = 2 and mirrors (identical) the values for the PNU (parameter number) and PWE (parameter value).

c) Switch on the new operating mode by setting the control word (STW) Bit 10 to 1.

This validates the process data.

If, for example, point a) is not observed, the servo amplifier transmits a negative answer: (response ID=7)

Byte 1 2345678

0111 0011 1010 0010 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0001 0001

PKE IND PWE

And the number that is transferred in the PWE section represents the error number, and can be looked up in the table in Chapter 3.1.1.2. In this case, error no. 17, “Task impossible because of operating state” will be signaled.

PROFIBUS for S300/S400/S600/S700 45

Page 46

Appendix 04/2017 Kollmorgen

6.1.3 Enable the servo amplifier

The hardware enable signal (24V) must be applied, as a precondition for enabling the servo ampli fier via the PROFIBUS. The enable through PROFIBUS can be made by setting the bit combination for the “Operation enabled” state in the control word (STW).

Byte 9 10 11 12

xxx0 x1xx 0011 1111 xxxx xxxx xxxx xxxx

STW HSW

The servo amplifier then reports back the corresponding state in its status word (ZSW), or indicates a warning or error message.

ZSW HSW

6.1.4 Start jog mode (on positioning opmode)

Jog mode is started in a similar manner to homing. To start, Bit 8 STW must be set. The jog velocity is given by the product of the 16-bit main setpoint in PZD2 and the multiplier defined by PNU 1894. The sign of the main setpoint determines the direction of movement.

It is not necessary to have a reference point set for jogging.

6.1.5 Set reference point

Take care that the position of the reference point permits the following positioning operations. The parameterized software limit-switches in the servo amplifier may not be effective. The axis could then drive up to the hardware limit-switch or the mechanical stop. There is a danger of damage being caused.

The control word (STW) Bit 12 = 1 defines the present position as being the reference point. The positioning functions are enabled. The shifting of the zero point (NI-offset) is ineffective. The replay “Reference point set” is made through Bit 17 in the manufacturer-specific status register (PNU 1002) or Bit 1 (manufacturer status of the process data).

Conditions:

PNU930 ¹ -16 No motion function active manufacturer specific status, process data 5 bit 0

Kollmorgen 04/2017 Appendix

6.1.6 Start homing run

After switching on the 24V auxiliary voltage the system must first of all carry out a homing run. Take care that the position of the machine zero point (reference point) permits the following positioning operations. The parameterized software limit-switches in the servo amplifier may not be effective. The axis could then drive up to the hardware limit-switch or the mechanical stop. There is a danger of damage being caused. If the reference point (machine zero point) is approached too fast, with high moments of inertia in the system, then it might be overrun, and the axis could then drive up to the hardware limit-switch or the mechanical stop. There is a danger of damage being caused.

The homing run is started by the control word (STW) Bit 11 = 1. The start of the homing run is detected by a positive transition edge for Bit 11. If Bit 11 is set to 0 again, before the reference point has been reached, then the homing run is can celed. Status word (ZSW) Bit 17 remains at 0 (reference point not set).

A set reference point is a precondition for all the positioning functions of the linear axis. The reference point switch is wired up to a digital input on the servo amplifier. Depending on the type of homing run, you can freely shift the zero crossing point of the motor shaft within one turn, by using the parameter “Zero-point offset” (NI-offset). Furthermore, you can fix the position value to be the reference point by using the reference offset.

After the homing run, the amplifier signals “InPosition”, thereby enabling the position controller. The velocity for the homing run is transmitted with the setpoint HSW (PZD 2), as a 16-bit value. Multiplying this by the value of PNU 1894 determines the 32-bit speed. The sign is not evaluated.

Conditions :

State of the state machine = “Operation enabled” No warning message (ZSW Bit7=0)

The following diagram uses the homing run Type 1 (negative direction of motion, positive rotation, starting point in negative direction relative to the reference switch) as an example to illustrate the signal sequence of the relevant bits in the manufacturer-specific state.

After the homing run has been completed, Bit 11 STW must be set to 0 again.

Alternatively, the reference point can also be set at the actual position. This can be achieved by setting Bit 12 STW, or by setting the homing run type 0 with PNU 1773 and subsequent start of the homing run by Bit 11 STW .

6.1.7 Start a motion task

Motion tasks are started by a transition edge (positive or negative) at Bit 6 STW. Bit 14 STW is used to decide whether a stored motion task or a direct motion task should be carried out.

Conditions:

Hardware enable is present. Amplifier is in the “Operation enabled” state. For linear axis: reference point is set.

Example: start the EEPROM motion task number 10:

STW HSW

* F stands for a transition edge, the state of Bit 6 STW also depends on the previous state.

By setting bit 5 in the manufacturer-specific status, the amplifier indicates that it has accepted the motion task and is carrying it out.

6.1.8 Start a direct motion task

If the motion task data is to be directly sent from the controller, then a direct motion task must be used. In this case, the target position, velocity and type of motion task are transferred using the pro cess data channel (PZD), together with the call of the motion task. If required, further parameters for this motion task (e.g. ramps) can be transferred previously by parameter tasks.

Note: after an error has occurred in parameter transmission (AK = 7), a “Zero telegram” should be transmitted, i.e. the first 8 bytes of the transmit telegram from the PLC should be kept at 0, until the servo amplifier has responded with a zero telegram.

The KP value for the current controller is to be set through the ASCII channel. The command is then MLGQ_1.985. Here the understroke stands for a space. Since every tele gram only has 10 positions available for the transmission of ASCII characters, the termination of the line (“CR LF”) must be transmitted in a second telegram. Conditions:

Note: The sequence of response telegrams shown above is only one of many

possibilities (for the same response from the servo amplifier). Because of the transmission rate and the internal synchronization mechanism, it can happen that process data sections remain empty and so the response is broken into segments. This could possibly alter the number of response telegrams.
