8.2 Electrical interference suppression
Signal wires should be installed separately from load power lines and with a safe
distance of at least 0.5 m to capacitive and inductive interferences such as contactors,
relays, motors, switching power supplies, timed controllers.
If interferences occur in spite of applying all above mentioned measures proceed as
follows:
1. Add RC elements over contactor coils of AC contactors (for example 0,1 µF/100
Ω)
2. Add recovery diodes over DC inductances
3. Add RC elements over each drive phase (in connector box of the drive).
4. Do not connect the GND potential with PE (earth potential)!
Install a power filter before the external power supply
8.3 Restart after fault clearance
After fault clearance:
1. Reset emergency stop switch.
2. Quit disturbance on indicator.
3. Make sure that no person is located in the danger zone.
4. Start operating as explained in the instructions.
