5.3  Parameter "P2040" (object 0x27F8*), telegram failure 
time  
Parameter "P2040" (object 0x27F8*) is used to activate the monitoring of the 
telegram failure time. This parameter is used to set the time for cyclic monitoring of 
the master (life guarding and SYNC ). Fault F0070 is activated if the CANopen 
option module does not receive a new telegram within the telegram failure time 
(this depends on the setting of P2041.04, (or object 0x27F9* sub 4) and then 
specifies the response to this fault).  
If one of two telegrams fails, the particular alarm (refer to Section 7.2) and a fault 
telegram are activated. 
The monitoring function is activated as standard (default setting). If the master 
does not immediately start with node guarding, then this results in a fault state of 
the drive.. 
 
"P2040" = 0  no monitoring 
"P2040" > 0  telegram failure time in milliseconds (as standard > 0 !) 
 
Caution! 
When commissioning the system for the first time, we recommend that 
parameter "P2040" (object 0x27F8*) is set to zero in order to prevent the drive 
going into a fault state.
