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
l
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
l
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.
l
Implement appropriate protective measures to ensure that any unin­tended start-up of the machines cannot result in dangerous situations for personnel or machinery.
l
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.
l
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:
l
Remove the cover of the option slot (see installation manual of the servo amplifier.)
l
Take care that no small items (such as screws) fall into the open option slot.
l
Push the expansion card carefully into the guide rails that are provided, without twisting it.
l
Press the expansion card firmly into the slot, until the front cover touches the fixing lugs. This ensures that the connectors make good contact.
l
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:
l
keypad on the front panel of the servo amplifier (see instructions manual)
l
setup software: screen page “CAN / Fieldbus” (see online help)
l
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.

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.

3 Device Profile

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.
