Digital inputs Overview Note: For digital inputs with 5 V, the length of the supply lines must not exceed 3 meters. Note: The digital inputs are sampled once per millisecond. Signal changes at the input less than one millisecond in duration are not processed. The following inputs are available: Input Special function Switching threshold switchable Differential / single-ended 1 Negative limit switch no, 24 V fixed single-ended 2 Positive limit switch no, 24 V fixed single-ended 3 Home switch no, 24 V fixed single-ended 4 –Enable The inputs for enable, direction and clock can only be switched together between 5 V or 24 V (see 3240h:06h) The inputs for enable, direction and clock can only be switched together. In the "single-ended" mode, the respective negative input (e.g., "-Enable") is deactivated (see 3240h:07h) 4 +Enable 5 –Direction 5 +Direction 6 –Clock 6 +Clock Object entries The value of an input can be manipulated using the following OD settings, whereby only the corresponding bit acts on the input here. 3240h:01h (Special Function Enable): This bit allows special functions of an input to be switched off (value "0") or on (value "1"). If input 1 is not used as, e. g., a negative limit switch, the special function must be switched off to prevent an erroneous response to the signal generator. The object has no effect on bits 16 to 31. The firmware evaluates the following bits: Bit 0: Negative limit switch (see Limitation of the range of motion) Bit 1: Positive limit switch (see Limitation of the range of motion) Bit 2: Home switch (see Homing) Bit 3: Interlock (see interlock function) If, for example, two limit switches and one home switch are used, bits 0–2 in 3240h:01h must be set to "1". 3240h:02h (Function Inverted): This subindex switches from normally open logic (a logical high level at the input yields the value "1" in object 60FDh) to normally closed logic (the logical high level at the input yields the value "0"). This applies for the special functions (except for the clock and direction inputs) and for the normal inputs. If the bit has the value "0", normally open logic applies; for the value "1", normally closed logic applies. Bit 0 changes the logic of input 1, bit 1 changes the logic of input 2, etc. 3240h:03h (Force Enable): This subindex switches on the software simulation of input values if the corresponding bit is set to "1". In this case, the actual values are no longer used in object 3240h:04h, but rather the set values for the respective input. 3240h:04h (Force Value): This bit specifies the value that is to be read as the input value if the same bit was set in object 3240h:03h. 3240h:05h (Raw Value): This object contains the unmodified input value. 3240h:06h (Input Range Select): This can be used to switch inputs – that are equipped with this function – from the switching threshold of 5 V (value "0") to the switching threshold of 24 V (value "1"). 3240h:07h (Differential Select): With the inputs, this subindex switches between "single-ended input" (value "0" in the subindex) and "differential input" (value "1" in the subindex) once for all inputs. 60FDh (Digital Inputs): This object contains a summary of the inputs and the special functions. Computation of the inputs Computation of the input signal using the example of input 1: The value at bit 0 of object 60FDh is interpreted by the firmware as negative limit switch; the result of the complete computation is stored in bit 16. Input Routing Principle To perform the assignment of the inputs more flexibly, there is a mode called Input Routing Mode. This assigns a signal of a source to a bit in object 60FDh. Activation This mode is activated by setting object 3240h:08h (Routing Enable) to "1" . Note: Entries 3240h:01h to 3240:04h then have no function until Input Routing is again switched off. Note: If Input Routing is switched on, the initial values of 3242h are changed and correspond to the function of the input as it was before activation of Input Routing. The inputs of the controller behave the same with activation of Input Routing. Therefore, you should not switch back and forth between the normal mode and Input Routing. Routing Object 3242h determines which signal source is routed to which bit of 60FDh. Subindex 01h of 3242h determines bit 0, subindex 02h determines bit 1, and so forth. The signal sources and their numbers can be found in the following lists. Number dec hex Signal source 00 00 Signal is always 0 01 01 physical input 1 02 02 Physical input 2 03 03 Physical input 3 04 04 Physical input 4 05 05 Physical input 5 06 06 Physical input 6 07 07 Physical input 7 08 08 Physical input 8 09 09 Physical input 9 10 0A physical input 10 11 0B Physical input 11 12 0C physical input 12 13 0D Physical input 13 14 0E Physical input 14 15 0F Physical input 15 16 10 Physical input 16 65 41 Hall input "U" 66 42 Hall input "V" 67 43 Hall input "W" 68 44 Encoder input "A" 69 45 Encoder input "B" 70 46 Encoder input "Index" 71 47 USB Power Signal The following table describes the inverted signals of the previous table.

The routing for bit 16 is written in 3242h:11h. Hence, object 3242h:11h must be set to the value "1". Interlock function The interlock function is a release that you control via bit 3 in 60FDh. If this bit is set to "1", the motor can move. If the bit is set to "0", the controller switches to the error state and the action stored in 605Eh is executed. To activate the interlock function, you must switch on the special function by setting bit 3 in 3240:01h to "1". Use Input Routing to define which signal source is routed to bit 3 of 60FDh and is to control the interlock function. Example Input 4 is to be routed to bit 3 of object 60FDh to control the interlock function. A low level is to result in an error state. To activate the Input Routing, set 3240h:08h to "1". To route input 4 to bit 3, set 3242h:04h to "4".
