•
Remove the pin from the breather plug.
F
The pin in the breather plug prevents the lubricant from leaking during shipment of the unit. If the
pin is not removed from the breather plug before operating, pressure could build up in the gearbox
and cause lubrication leakage.
•
Connect the power supply plug to the motor.
3.4 Start-up procedure
•
Make sure that the conditions at the operating site correspond to the operating conditions for which
the drive is designed or selected for (including indoor/outdoor use, ambient temperature/radiance
temperature, wind, dust, splashing, snow, water, handling hazardous materials, fire risk, etc).
•
Check that the supply voltage and frequency are suitable for the motor and brake.
•
Check that the direction of rotation is correct. Verify that the direction corresponds to the control
signal. In multi-motor systems, check that all the units function correctly in series. If any of the motors
do not operate properly, an electrician must check and correct the electrical connections. Refer to the
electrical instructions and wiring diagram for further information.
F
Be prepared for the equipment to move in the wrong direction when first testing.
•
Check the function of the brake. The brake is factory set. Adjust the air gap if the braking distance is
too long (with nominal load) or too short or the brake is not releasing. Refer to the motor instructions
section for further information. If an inverter controls the motor, check that inverter parameters are set
up correctly.
•
Make an audible check of the machinery while operating. A very loud growling sound indicates an
incorrect electrical connection to the motor. This must be corrected immediately. A regular distinct
clatter sound is an indication of a bad bearing in the geartrain.
•
Check with your hand for excessive vibration while the unit is running. The cause of the excessive
vibration must be identified. If the machinery causes an inverter fault, it must be checked out.
•
Check the running temperature of the motor during the long-term operation. The temperature rise of
the F-class motor must not exceed 100°C. If the motor is overheating, it may be due to a faulty motor,
or poor cooling or an overloaded motor. The reason must be identified and corrected.
•
Make sure that any safety devices (limit switches, etc) bypassed for testing purposes are restored to
full operational status.
3.5 Inspection and service procedure for Drive
Carry out the following inspections and servicing procedures at regular intervals. See 'Inspection and
servicing intervals' section for the inspections and servicing schedule.
•
Check the tightness of the bolts.
•
Check that the breather plug is not blocked by foreign obstacles or remove the pin from the plug.
•
Check the gearbox for leakage.
•
Check the traveling motion: acceleration and deceleration.
•
Check the brake for wear. If necessary, clean the brake and replace the friction discs.
•
Check the air gap and adjust if necessary. Refer to the motor instructions section for further
information.
•
If an inverter controls the motor, check that the inverter operates correctly.
•
Gears are lubricated with semi-fluid grease and does not require adding or changing the lubricant
when used in normal operating conditions.
