Issue:
Need to read the encoder count over a serial communication network from a drive.
Product Line:
ATV71 or ATV930 with optional encoder card installed
ATV340 with embedded encoder input or encoder option card installed
Environment:
ATV71 or ATV930 with optional encoder card installed
ATV340 with embedded encoder input or encoder option card installed
Cause:
How do you read the encoder pulse count through a network?
Resolution:
Code: Logic address: 16#15EB=5611
CANopen Index: 16#201A/C
DeviceNet path:16#7D/01/0C=125/01/12
Type: Unit (unsigned16) : Read only
Unit: value 1 per count
PUC (logic address 5611) is initialized to the value 0 when the drive is powered on. Every ms this parameter increases or decreases according to the direction of rotation (forward or reverse).
It is a 16 bit register and is not signed, that is to say when 65535 is reached, it goes back to 0.
It is not possible to write this parameter.
There is no detection of overflow
