Error Error message  Description/Action
F1452 
Anti-Clockwise 
Operation Locked 
Negative hardware limit switch or negative software 
limit switch reached. After acknowledgement of error 
it was tried to move in negative direction (anticlock-
wise). Negative direction is disabled as long as nega-
tive limit switch is active. 
Move axis in defined travel range again: In JOG 
mode, move in opposite direction or start positioning 
in opposite direction. 
F1453 
System bus-
Synchronization 
not activated 
Parameter 
Master Position Source 1122 of elec-
tronic gear is set to operation mode "11 - 
RxPDO1.Long1 extrapolated", but frequency inverter 
is not synchronized with data telegrams of system 
bus. 
Switch on system bus synchronization: 
Set Parameter 
Operation Mode 1180 to "1 - 
RxPDO1" or "10 - SYNC" (chapter "Master position 
source"). 
F1460 
Pos. HW-Lim. 
Switch: Illegal 
Signal Source 
Pos. HW Limit Switch 1138 is set to an illegal logic 
signal source or to a digital input of an expansion 
module (EM-S1IND, EM-S2IND or EM-S3IND) al-
though no expansion module is installed. The pa-
rameter must be set to an available digital input. 
F1461 
Pos. HW-Lim. 
Switch: Input dis-
abled by PWM-/FF-
Input 
The digital input for 
Pos. HW Limit Switch 1138 is 
set as PWM- or repetition frequency input. Set pa-
rameter 
Operation Mode 496 of the PWM-/ repeti-
tion frequency input to “0 - off” or to another digital 
input to use the digital input as HW-limit switch in-
put. 
F1462 
Pos. HW-Lim. 
Switch: Input dis-
abled by Index-
Contr. 
The digital input for 
Pos. HW Limit Switch 1138 is 
set as input for index control. Check the settings of 
Operation Mode 598 of the index control and Index
Controller Release
 96. Alternatively use another 
digital input for the connection of the HW-limit 
switch. 
F1463 
Pos. HW-Lim. 
Switch: Wrong 
Op.-Mode for MFI1
The multifunction input MFI1 at terminal X210B.6 is 
set as voltage input or current input via parameter 
Operation Mode 452. Set Operation Mode 452 to 
“3 - Digital Input” to use the multifunction input as 
HW-limit switch input. 
F1464 
Pos. HW-Lim. 
Switch: Input dis-
abled by En-
coder 1 
The digital input for 
Pos. HW Limit Switch 1138 is 
set as encoder input. Set 
Operation Mode 490 of 
the speed sensor 1 to “0 - off” to use the digital input 
as HW-limit switch input. Alternatively use another 
digital input for the connection of the HW-limit 
switch. 
F1465 
Pos. HW-Lim. 
Switch: Input dis-
abled by En-
coder 2 
The digital input for 
Pos. HW Limit Switch 1138 is 
set as encoder input. Set 
Operation Mode 493 of 
the speed sensor 2 to “0 - off” to use the digital input 
as HW-limit switch input. Alternatively use another 
digital input for the connection of the HW-limit 
switch. 
F1466 
Pos. HW-Lim. 
Switch: Wrong 
Op.-Mode for EM-
S1IOD 
The digital port EM-S1IOD of an expansion module is 
misadjusted for the evaluation of a HW-limit switch. 
The parameter 
Operation Mode 558 must be set to 
“0 - input”.
