When a value of "Trip" is selected in Pr S.01.011 and no cyclic communications have
been detected in a time period defined by Pr S.01.010 then the drive will trip displaying
"SlotX Error" with a sub-trip string of "Link loss".
If the network loss timeout time (Pr S.01.010) is reduced too far, spurious network
losses may occur due to a time-out occurring before the time period under normal
operating conditions.
Network loss detection can be disabled by setting Pr S.01.010 to 0. It is the user's
responsibility to ensure that adequate safety precautions are taken to prevent damage
or injury by disabling the drive in the event of a loss of communications.
WARNING
If Pr S.01.011 is set to "Send flt values", the fault values entered in Pr S.04.001 to
Pr S.04.028 are sent to the mapped output parameters when a network timeout error
occurs.
e.g. if Pr S.03.001 = 20021 and Pr S.03.002 = 20022 and a timeout error occurs, the
value in Pr S.04.001 will be sent to Pr 20.021 and the value in Pr S.04.002 will be sent
to Pr 20.022 as defined in the out mapping parameters.
If Pr S.01.011 is set to "Clear output", all PLC output parameter values are set to zero.
e.g. if Pr S.03.001 = 20021 and Pr S.03.002 = 20022 and a timeout error occurs,
Pr 20.021 and Pr 20.022 will be set to 0.
If Pr S.01.011 is set to "Hold last", the last values sent by the PLC master are held in the
mapped output parameters.
e.g. if Pr S.03.001 = 20021 and Pr S.03.002 = 20022 and a timeout error occurs,
Pr 20.021 and Pr 20.022 will equal the last values sent by the PLC master.
If Pr S.01.011 is set to "No action", then the module will not write any value to any
mapped output parameters.
Timeout Event Destination
S.01.012
Timeout Event Type
S.01.013
When a timeout occurs, the SI-DeviceNet module can trigger an event defined by
Pr S.01.013 to a destination, such as an Option Module installed to a different slot on
the drive, defined by Pr S.01.012.
NOTE
If triggering an event to a different Option Module, Pr S.01.012 must point to a slot
where a compatible Option Module is installed to.
