Position counter in SLSM-PSM and SL PSM causes a position drift every time upon enabling the inverter.

Description of the behavior:

Upon enabling the inverte, a position jump occurs in the position counter that does not correspond to any physical movement of the axis (“position drift”).

Conditions under which the behavior occurs:

Control mode: SLSM-PSM or SL PSM
The source for the position counter is set to “Internal Motor Model”
The position jump occurs every time upon enabling the inverter, regardless of the axis movement.

Affected products:

i650 Motec /cabinet

i550 Motec /cabinet /Protec

i510

Short-term measures, recommendations, assessment:

After each enable, perform a reference run before positioning.
