Remedy
6165: Fault in reception of the PROFIsafe telegram. This fault can
also arise if the inverter has received an inconsistent or out-of-date
PROFIsafe telegram after a power on reset or after the
PROFIBUS/PROFINET line has been connected.
Check the configuration and communication in the inverter.
•
Check the value of the F_WD_Time F-parameter in the inverter.
•
Increase the value.
6166: Time monitoring fault in reception of the PROFIsafe telegram.
Check the configuration of the communication in the inverter.
•
Check the setting of the F_WD_Time value in the inverter.
•
Increase the value.
Evaluate the diagnostic information in the F host.
•
Check the PROFIsafe connection.
•
Not necessary.
Not necessary.
1. Select STO, and then deselect again.
2. If it cannot be acknowledged, replace the Control Unit.
Depending on the fault value, check the following:
10, 11: p1278 ≠ 0, brake not connected, cable interrupted or ground
fault
20: Short-circuit in the brake winding
30, 31, 40: Brake not connected or a short-circuit in the brake
winding
50: Fault in the Safe Brake Relay, in the Control Unit or in the Power
Module.
Check and correct the parameterization of the motor holding brake:
The following settings can result in this message:
p1215 = 0 and p9602 = 1.
•
p1215 = 3 and p9602 = 1.
•
See Section Corrective maintenance (Page 251).
1. Switch off the Control Unit power supply and then on again.
2. If it cannot be acknowledged, replace the Control Unit.
See Section Acceptance tests for the safety functions (Page 156).
1. Switch off the Control Unit power supply and then on again.
2. If it cannot be acknowledged, replace the Control Unit.
Check the PROFIBUS configuration of the safety slot on the master
side and on the Control Unit.
