6.1.8.3 Installation Safety and Warnings

General
•
The machine surface that comes in contact with
the servo drive flange must be unpainted to
guarantee good thermal behavior of the servo
drive, and to minimize EMI disturbance in the
servo system.
•
Do not machine the shaft.
•
Do not use the servo drive if the shaft does not
match the coupling arrangement.
•
Do not hammer the servo and do not use a
hammer for fitting because this will damage the
6 6 equipment.
•
Ensure that the machinery is at a complete
standstill before installing the servo drive.
•
Ensure that the machinery is at a complete
standstill and secured against unintended start
before doing any work on the servo drive, for
example dismounting the servo drive.
•
During operation, the surface of both motor and
electronic housing could reach temperatures of
>100 °C. Ensure that the surface has cooled down
before dismounting the servo drive.
•
Avoid brute force while dismounting the servo
drive and follow the instructions in the VLT
Integrated Servo Drive ISD
Instructions.
•
Before working on the power connector
(connecting and disconnecting the M23
connector), disconnect the mains supply and wait
for the discharge time (see chapter 1.6 Safety) to
elapse.
•
Mount the protection caps for any servo drive
connectors that are not in use.
Warnings and notes for servo drive with optional brake
•
Use an additional, external, mechanical brake to
ensure personal safety in case of hanging loads
(vertical axes). If the brake is released, then the
rotor can be moved without remanent torque.
•
The holding brakes are designed as standstill
brakes and are not suitable for repeated
operational braking. Frequent operational braking
results in premature wear and failure of the
holding brake.
Warnings and notes for servo drive with optional shaft
seal
•
Do not apply any axial load to the shaft seal.
•
Prevent the seal from becoming dry by using
adequate lubrication.

•
Harsh environmental conditions, for example
frictional heat, dirt, dust, or chemical substances,
can reduce the lifetime of the shaft seal.
Therefore the lifetime depends on the specific
application.
•
The maintenance task for the shaft seal is
explained in Table 6.12.
Maintenance task Maintenance interval
Check the Recommended every
condition and 4500 hours. A shorter or
check for leakage longer interval is possible
depending on the
application.
Table 6.12 Maintenance Task: Shaft Seal
Instruction
If damaged,
replace the
shaft seal.
