1.2 Safety Guidelines

1.2.1 Notes on Protecting Personnel

The following problems can occur when operating a drive or a drive

package for the first time:

• wiring fault

• fault in NC program

• for operational reasons, monitors are not working

These can cause increased risk of accidents and can lead to

• personal injuries,

• damage to drives and

• machines.

The drive may only be operated as prescribed in the relevant

documentation!

There is danger from moving axes due to

• unintentional starting due to malfunctions and faults and

• operation in the speed or position control circuit.

Precautionary measures for personnel:

• Personnel must not remain in the area of the machine in which

movements can take place.

• The drives must be stopped and secured against unintentional starting

when personnel are working in the hazardous area.

Precautionary measures against unintentional starting:

• Disconnect the power contactor (EMERGENCY STOP).

• Switch the master switch off during prolonged breaks in operation.

Dangerous voltages on equipment terminals:

• mains voltage L1, L2 and L3

• DC bus voltage L+,L-

• motor voltage A1, A2 and A3

Open master switches and secure against reconnection prior

to working on electrical equipment. The drives must be securely

locked because voltage appears on the motor cables when the

motors rotate!
