Position value for channel 2 via parameter (Ec.28)
An encoder is connected to the master control. The position value is written to parameter Ec.28 via bus.
Rotary encoder: The control detects the whole revolutions and outputs a continuous position value to
Ec.28
Linear encoder: The controller detects the position value and outputs it toEc.28
Adjustment:
Ec.10 = 30 = „Position via Ec.28“. Independent of connection to channel 2.
Increments per revolution Ec.11 (128….16384, default 1024 inc)
Multiturn resolution Ec.21 ( 32….32, default 32 )
Resolution Ec.17 ( 2….9, default 9)
Position format:
The position value in a range of -2^31….2^31.1 is described in Ec.28.
The display standardization can not be changed with Ec.41. The overow detection after power-on is not
supported!
