CANopen encoder

Status LED 4.10.2
The status LED is a two-colour LED with two functions; a green LED (run status)
and a red LED (error status)�
LED Display
green flashing encoder in the NMT status operational
green blinking encoder in the NMT status stopped
green lighting encoder in the NMT status pre-operational
red out no error
red blinking overflow on the error counter
red double blinking guard event or heartbeat event occurred
red lights the encoder is in the bus off status
If the communication of the encoder is error free in the operating status, the
module LED shows green and the status LED flashes green�
Profile overview 5
The encoder profile defines the functions of the encoders connected to CANopen�
The operating functions are divided in two device classes:
Class 1
The mandatory class with basic functions which all encoders must support� As an
option, class 1 encoders can support selected functions of class 2� However, these
functions must be implemented according to the profile�
Class 2
The encoder must support all functions of class 1 as well as all functions defined in
class 2�
Functions of class 2
Transmission of the absolute position value with polling, cyclic or SYNC mode� ●
Speed and acceleration output values ●
Change of the code sequence ●
Presettings ●
Scaling of the encoder resolution ●
Advanced diagnosis
Encoder identification ●
Operating status ●
Operating time ●
