Fixed as of:
4.7.0.13
Behavior of the new version:
The drive switches to the “ready to switch on” state.
Description of the behavior:
Compared to i550cabinet or i550protec, the iSM remains in the “switch on disabled” state instead of returning to the “ready to switch on” state. There are some off-the-shelf PLC blocks from manufacturers (e.g., the NC axis from Beckhoff) that expect the “ready to switch on” state and do not send a new transition command. As a result, the drive or the application freezes and cannot recover on its own.
Conditions under which this behavior occurs:
As soon as the fieldbus control word in CiA mode (0x6060 = 2) remains unchanged, but a fault is triggered or the supply voltage (24V control voltage still active) is turned off and then back on.
Affected products:
ISM (iSeriesMotec) fieldbus communication
Short-term measures, recommendations, assessment:
Manually trigger the state change or write a program routine to do so.
