Stop!
Maximum permissible peak current may never be exceeded!
ƒ Commission drives and check all individual functions, like for instance
– the torque behaviour and current consumption,
– the braking effect of the braking unit mounted,
– the output signal of the tachogenerator.
ƒ In the case of failures or faults, see chapter 8 Troubleshooting and fault
elimination".
6.2 During operation
(
Stop!
ƒ Fire hazard! Do not clean or spray motors with flammable detergents or
solvents.
ƒ Avoid overheating! Deposits on the drives impede the heat dissipation
required and have to be removed regularly.
}
Danger!
During operation, motor surfaces may not be touched. According to the
operating status, the surface temperature for motors can be up to 95°C. For
the protection against burn injuries, provide protection against contact, if
necessary. Observe cooling−off times!
ƒ According to the operating conditions, carry out regular inspections during
operation.
In doing this, especially observe:
– Unusual or undue noise or temperature development,
– Loose fixing elements,
– The condition of the electrical cables,
– Oily drive components or leakages,
– Increased vibrations and the like,
– Speed variations
– Hindered heat dissipation by deposits on the drive system and in the cooling ducts.
ƒ If faults occur, go through the table for fault diagnostics in chapter 8. If the fault
cannot be eliminated, please inform the Lenze service department.
