The updating of the IPC is affected by the Clock Resolution that may be set to 1 2 or 4 Clocks Cycle SOFTWARE OUTPUTS The XPC eXternal Position Counter is a latch counter being equalized to the IPC upon user s request either via PC s software or by a hardware real time input Event Signal produced when a pre defined condition is met This software Event Signal is supplied also in the hardware outputs as described in section 1 2 2 11 The user may select one of the following as the pre defined condition that becomes the trigger of the event e IPC SPR Each Encoder Interface includes an SPR Set Point Register being adjustable by the user In case the user selects this condition an event occurs when IPC SPR e IPC Overflow In case the user selects this condition an event occurs when there s overflow in the IPC that is IPC changes from 16777215 to 0 or vice versa e Index In case the user selects this condition an event occurs when an index marker signal arrives from user s encoder 1 1 3 EIWAREINPUT a Data Request to request an XPC update For example upon Data Request on the A axis the following operation is done XPC IPC A Notes 1 Data Request may be applied on a single axis or all at once on axes pair A B or C D or all four axes 2 Besides this software Data Request there is also a hardware real time Data Request applied on all four axes as described in section 1 2 1 ii b Reset
