ROUTINE MAINTENANCE
• All work relating to installation,
commissioning and maintenance must be
carried out by experienced, qualified
personnel. Before carrying out any work,
disconnect and lock the Commander ID300/302
power supply circuit and wait 10 minutes for the
capacitors to discharge.
Checks after start-up
After approximately 50 hours’ operation, check that the
screws fixing the motor and the coupling device are still
tight. In the case of chain or belt transmission, check
that the tension is correctly adjusted.
If the brake wear needs to be checked: measure
the air gap to check that it conforms to the maximum
authorized dimension (see the “Adjusting the air gap”
procedure in section 4.4 ref. 5287 FFB maintenance).
Cleaning
To ensure the machine operates correctly, remove any
dust or foreign bodies which might clog the motor cover
grille (and drive fan grille if present), and the motor /
drive housing fins.
Precaution: before carrying out any cleaning operation
check that the motor is completely sealed (terminal
box, drain holes, etc). Dry cleaning (vacuuming or
compressed air) is always preferable to wet cleaning.
Always clean at reduced pressure from the
centre of the motor towards the extremities
to avoid introducing dust and particles
under the seals.
CAUTION
• Do not dismantle the Commander ID300/302 while
it is still under guarantee, as this would then
immediately become null and void.
• Certain components which are sensitive to
electrostatic discharge may be destroyed simply
by touching them. Do not leave any metal object in
the connection area, as this could cause a
short-circuit.
Draining off condensation water
Temperature variations cause condensation to form
inside the motor, which must be removed before it
adversely affects motor operation. Condensation drain
holes, located at the bottom of the motors (bearing in
mind their operating position) are sealed with plugs
which must be removed and then replaced every six
months (if they were not replaced, the motor degree of
protection would no longer be maintained). Clean the
orifices and plugs before reassembling them.
NOTE
In conditions of high humidity and significant
temperature variations, a shorter period is
recommended. As long as it poses no risk to the
motor protection, the condensation drain plugs can be
removed.
Bearings
The permanently greased bearings offer long grease
life and therefore lubrication for the lifetime of the
machines. The grease life depends of speed of rotation
and ambient temperature. For more details, please
refer to the motor documentation ref.4850 available on
www.leroy-somer.com.
CAUTION
For details about motor, gear-motor or FFB brake
preventive and routine maintenance, please see the
relevant documentation available on www.leroy-
somer.com.
