5 Operation of the Servo Motor
5.1 Preparations
Before initial operation and after major inspections, check the complete plant both from
a mechanical and electrical point of view.
Examine that
• the installation and the operating conditions comply with the specified name plate
data.
• the motor is properly installed and aligned.
• the driving elements are properly adjusted (e.g. proper belt tension, coupling prop-
erly aligned and balanced).
• the motor and its monitoring devices are properly wired.
• the earthing and equipotential bonding have been made as specified in the appli -
cable regulations.
• all fastening screws, connecting elements and electrical connections are properly
tightened.
• the key is safed unless prevented otherwise by driving elements such as pulleys,
couplings etc.
• the separate ventilation is correctly connected and in proper service condition.
• the direction of rotation of the fan motor corresponds with the direction arrow on
the fan housing.
• the cooling air flow is not impaired (the hot outlet cooling air must not be drawn in
by the fan!).
• eventually existing brakes are O.K.
5.2 Initial start-up
The following measures are recommended to be taken after installing or inspecting the
motors:
• Start the motor with no load.
• Check the mechanical running for any noise or vibrations on the bearings or end
shields.
• If there is any abnormal noise or the motor runs unevenly, switch it off immediately
and find out the cause.
• If the mechanical running improves immediately after the motor has been switched
off, there is an electrical or magnetic cause. If this is not the case, there is a me-
chanical cause.
• If the mechanical running is smooth at no load, load the motor. Check the running
smoothness, measure the voltage, current and power and record them. Measure
and record these values also for the driven equipment, if possible.
• Monitor the temperatures of the bearings, windings etc. until they have stabilised
and record the values (as far as this is possible with the available measuring
equipment).
