DOK-ECODR3-DKC16*UL***-IB01-EN-P
Note:
• Exceeding allowed control voltage generates error
message "+24 volt error". (=> See also functional firmware
description.)
• Control voltage failure causes the running motor to coast
torque-free (without brake).
DANGER
Dangerous movements due to unbraked
coasting of motor with control voltage failure!
⇒ Personnel should not remain within the area of the
machine with moving parts. Possible preventive
steps against unauthorized access are:
– protective fencing
– bars
– covers
– light barriers
⇒ The fences must be able to withstand the maximum
possible force that the machine can generate.
Drive halt (AH) and Drive enable (RF)
Note:
