SOCAPEL SA SOFTWARE FOR SYNCHRONIZATION OF AXES 024.8068.A10.6.3 Instruction ALISUInstruction code : 28 (hexa : 1C).Data bytes :Answer byte :Tests :NoneStatus STATA.None.The purpose <strong>of</strong> this instruction is to save <strong>the</strong> instantaneous physical position <strong>of</strong> <strong>the</strong>slave shaft as a reference <strong>for</strong> later synchronizing steps. It provokes zero-reset <strong>of</strong> INTVand as a result corrects variable PCOR and parameter CPCOR, to avoid changes inreference position PHIRE (see description <strong>of</strong> parameter CPCOR and explanation <strong>of</strong>independence <strong>of</strong> resolver zero).In order to limit <strong>the</strong> number <strong>of</strong> motor revolutions in parameter CPCOR, an INIPSinstruction can be executed previously.If instruction ALISU is executed only once (at commissioning), and not after eachreset, <strong>the</strong> CPCOR parameter must be saved in a SAVE instruction. In this case, <strong>the</strong>instruction ALISU should be preceded by an INIPS instruction to ensure that aparticular number <strong>of</strong> motor revolutions is not taken into account.10.6.4 Instruction ALIPOSInstruction code : 20 (hexa : 14).Data bytes :Answer byte :Tests :NoneStatus STATA.None.Like <strong>the</strong> instruction ALISU, this instruction saves a physical situation by initializing <strong>the</strong>variable PCOR and <strong>the</strong> parameter CPCOR.For this, ALIPOS takes account not only <strong>of</strong> <strong>the</strong> slave position, but <strong>of</strong> <strong>the</strong> relativepositioning <strong>of</strong> <strong>the</strong> master and slave shafts, to ensure <strong>the</strong>ir relationship is respectedsubsequently.ALIPOS does not reset INTV to zero; it adjusts PCOR in order to get zero-differencebetween INTV and PMUS, taking account <strong>of</strong> any periodicities involved.Apart from this, ALIPOS is used in <strong>the</strong> same way as <strong>the</strong> instruction ALISU. If ALISUimposes a prior INIPS value, ALIPOS will also ask <strong>for</strong> an INIPM.101
