Remedy
The PROFIsafe telegram number in p60022 is not suitable for the en‐
abled safety functions.
Check the following:
● If PROFIsafe is not enabled (p9601.3 = 0), PROFIsafe telegrams
must not be selected in p60022.
● If PROFIsafe is enabled (p9601.3 = 1), you must select a
PROFIsafe telegram in p60022.
● If transfer of the F-DI via PROFIsafe is selected (p9501.30 = 1),
you must select telegram 900 in p60022.
Check the setting of the safety functions.
You can find possible reasons for the message in the List Manual.
Use a Power Module that supports the safety functions.
Restrictions when using safety functions (Page 27)
Exit the simulation of the digital inputs of the Control Unit for the F-DI
(p0795).
1. Switch off the Control Unit power supply and then on again.
2. Contact Technical Support if it cannot be acknowledged.
2. Check: p9501 ≠ 0 and/or p9601 ≠ 0.
If this is the case, then correct both parameters.
3. Start the copy function again by entering the corresponding value
into p9700.
The inverter has identified a defect:
1. Switch off the Control Unit power supply and then on again.
2. Contact Technical Support if it cannot be acknowledged.
You have not configured the "STO via Power Module terminals" func‐
tion, but you have activated the terminals on the PM240‑2 or
PM240P‑2 Power Module:
1. Set the switch for the fail-safe digital input of the Power Module
(STO_A and STO_B) into the "OFF" position.
Set the signal at the F-DI to acknowledge the safety functions for a
logical 0 signal.
The ratio between the rated power unit current (r0207[0]) and rated
motor current (p0305) should be greater than 5.
In operation, message C01711 or C30711 can be sporadically output
with values
1041 ... 1044.
Use a suitable power unit with a lower power rating or a motor with a
higher power rating.
The set time (p9661) to monitor the forced checking procedure (test
stop) for the "STO via Power Module terminals" function has been
exceeded.
Deselect the "STO via Power Module terminals" function and then se‐
lect again.
