Warning
During operation and up to about 5 minutes after the motor
controller is switched off, the external or internal braking resistance
can create dangerous intermediate circuit voltage, which can cause
death or severe bodily injury on contact.
Before performing maintenance work, make sure that the power
supply is switched off, interlocked and the intermediate circuit
discharged.
Switch off power to the electrical equipment via the main switch
and secure it against being switched back on. Wait until the
intermediate circuit is discharged for:
- maintenance work and repair
- cleaning
- long interruptions in operation.
Warning
Care must be taken during installation. During both installation and
later operation of the drive, make sure that no shavings, metal dust
or installation parts (screws, nuts, sections of pipe) fall into the
motor controller.
Also make sure that the external power supply of the control
section (24 V) is switched off.
Power to the power section must always be switched off before
switching off the 24 V power supply to the control section.
Warning
Perform work in the machine area Tonly with the AC or DC power
supply switched off and locked out.
Switched-off final stages or controller enable are not appropriate
lockouts. In case of malfunction, this can result in unintended
running of the drive.
Warning
Perform start-up with the motor running at idle to avoid
mechanical damage, such as through incorrect direction of
rotation.
