Lenze ¯ BA 33.0005 ¯ 5.0
Before initial commissioning, before commissioning after an extended standstill
period, or before commissioning after an overhaul of the motor, the following must be
checked:
¯ Measure the insulation resistance, in case of values £1 kW per volt of rated
voltage, dry the winding.
¯ Have all screwed connections of the mechanical and electrical parts been firmly
tightened?
¯ Is the unrestricted supply and removal of cooling air ensured?
¯ Has the PE conductor been connected correctly?
¯ Have the protective devices against overheating (temperature sensor evaluation)
been activated?
¯ Is the controller correctly parameterised for the motor?
( Controller operating instructions)
¯ Are the electrical connections o.k.?
¯ Does the motor connection have the correct phase sequence?
¯ Are rotating parts and surfaces which can become very hot protected against
accidental contact?
¯ Is the contact of good electrical conductivity if a PE connection on the motor
housing is used?
7.3 Functional test
¯ Check all functions of the drive after commissioning:
¯ Direction of rotation of the motor
– Direction of rotation in the disengaged state (see chapter "Electrical
connection").
¯ Torque behaviour and current consumption
¯ Function of the feedback system
