Warning
The servo drive controller may only be operated, maintained and/or
serviced by persons qualified and trained to work on or with elec-
trical devices.
Avoiding accidents, bodily injury and/or material damage:
Warning
Secure vertical axes to prevent them falling or lowering after the
motor is switched off using methods such as:
- mechanical locking of the vertical axis,
- external brake / arrester / clamp or
- sufficient counterweight of the axis.
Warning
The series-supplied motor holding brake or an external motor-
holding brake controlled by the drive controller alone is not
suitable for protecting human beings!
Warning
Switch the electrical equipment free of voltage via the main switch
and make sure that it cannot be switched on again. Wait until the
intermediate circuit is discharged in the following cases:
-
Maintenance work and commissioning
-
Cleaning
-
Long shutdown periods
Warning
The external or internal braking resistance is live and can carry a
dangerous intermediate circuit voltage for up to approx. 5 minutes
after the servo drive controller has been switched off. This can
cause serious bodily injury or even death if it is touched.
Before carrying out maintenance work, make sure that the
power supply is switched off and locked and that the intermedi-
ate circuit is discharged.
Warning
Proceed carefully with mounting. Ensure that no drilling shav-
ings, metal dust or mounting material (screws, nuts, wire cut-
tings) fall into the servo drive controller during mounting work
and subsequent operation.
Make also sure that the external voltage supply of the controller
(24V) is switched off.
