SK 2x5E with "PosiCon Functionality"
18 Subject to technical amendments BU 0210 GB
The possible bus load in the system always depends on the real-time specific to the system. Very good results
are achieved with a bus load less than 40%. Under no circumstances should a bus load greater than 80% be
selected. For the estimation of the bus load, the other possible bus traffic (setpoint and actual values for the
FIs and other bus participants) should also be taken into account.
Additional explanations about the CAN interface can be obtained from Manual BU 0060.
3.2.2.3 Parameterisation of the SK 2X5E
The appropriate settings for the CANopen absolute encoder must be parameterised via the parameters P514
"CAN Baud Rate" and P515 "CAN Address".
ATTENTION
Before the CANopen absolute encoder can be connected to the frequency inverter, the parameters
P514 "CAN Baud Rate" and P515 "CAN Address" must be parameterised!
Please note that with the SK 2x5E the baud rate can also be determined by the DIP switches on the
device.
The following setting should only be made if the CAN bus with the associated 24V supply is connected to all
devices.
The resolution of the absolute encoder is set via the parameter P605 "Absolute Encoder".
P605 [01] = Multi-turn resolution in Bit
P605 [02] = Single-turn resolution in Bit
The relevant settings should be obtained from the data sheet for the absolute encoder.
Example: for a 25Bit encoder (12 Bit multi-turn, 13 Bit single-turn):
P605 [01] = 12  4096 number of resolvable rotary encoder rotations
P605 [02] = 13  8192 resolution per rotary encoder rotation
The CAN absolute encoder is activated via parameter 604 "Encoder Type". The following settings are possible:
P604 = 1  CANopen absolute encoder (Auto), with automatic configuration active
P604 = 6  CANopen absolute encoder (Auto), with manual configuration active
The encoder can be used for the function "Optimum Path" with the following settings:
P604 = 5  CANopen absolute encoder optimum path (Auto), with automatic configuration active
P604 = 7  CANopen absolute encoder optimum path (Auto), with manual configuration active
