167 Activate coupling signal present
Cause – The input signal ”Activate coupling” is present. An edge of the input
signal is necessary to activate the coupling.
– In the jog mode, while traversing, the input signal ”coupling on” was
entered.
– The ”coupling in” input signal was entered in handwheel operation.
Remedy Reset ”Activate coupling” input signal
Acknowledge fault
Set the input signal again to switch-in the coupling
Acknowledgement RESET FAULT MEMORY
Stop response STOP II
168 Overflow, buffer memory
Cause Occurs for couplings with queue functionality.
A maximum of 16 positions can be saved in P0425:16.
Remedy Ensure that maximum 16 positions are saved.
Acknowledgement POWER ON
Stop response STOP IV
169 Coupling trigger missed
Cause Occurs for couplings with queue functionality.
Synchronizatin is requested using the KOPPLUNG_ON command and
it is identified that the position at which the coupling is switched-in, has
already bee passed.
Remedy Ensure that the slave drive was stationary for at least 1 IPO clock cycle
(P1010), before the coupling for the next element in the position
memory must be switched-in.
Acknowledgement RESET FAULT MEMORY
Stop response STOP IV
170 Coupling switched-out during the traversing program
Cause While the drive was executing a traversing program, the ”Activate cou-
pling” input signal was reset.
Remedy Only switch-out the coupling if the traversing program has been com-
pleted.
Acknowledgement RESET FAULT MEMORY
Stop response STOP IV
171 Coupling not possible
Cause While the drive was executing a traversing program, the ”Active cou-
pling” input signal was set.
Remedy Only switch-in the coupling if the traversing program has been com-
pleted.
Acknowledgement RESET FAULT MEMORY
Stop response STOP V
