Foreseeable misuse
The following list shows examples of incorrect rotary drive use:
• operating multiple drives on one shaft
• using the wrong type, insufficient power, no spring-return mechanism (despite being re-
quired), no ATEX (despite being required)
• adjusting drive even though it is live
• Allen key left in place
• sticking finger in hollow shaft
• selecting inadequate conductor cross-section for connection
• incorrect integration in the control system
• incorrect parameter setting – valve does not move into correct position, motor has insuf-
ficient torque
• working in explosive atmosphere at the drive unit
• operating with incorrect load
• runtime for the drive too high
