Technical Manual N5 (CANopen)
10 Description of the object dictionary
Change history
Firmware version FIR-v1540: "Savable" entry changed from "no" to
"yes, category: tuning".
Description
A negative value means that the encoder is driven in the opposite direction of the motor. This can be
corrected by reversing the polarity of a motor winding.
Tip
The unit is "pulses per revolution" (ppr), which corresponds to four times the resolution in "counts
per revolution" (cpr) (quadrature). This means that for an encoder with a resolution of, e.g., 1000
increments per revolution, the value in 2052
h
is 4000.
2056h Limit Switch Tolerance Band
Function
Specifies how far a limit switch may be passed over in the positive or negative direction before the
controller triggers an error.
This tolerance band is necessary, for example, to complete homing operations – in which limit switches
can be actuated – error free.
