SOCAPEL SA SOFTWARE FOR SYNCHRONIZATION OF AXES 024.8068.A10.7.2 Instruction STARTInstruction code : 13 (hexa : D).Data bytes :None.Answer byte :Status STATA.Tests :None.Causes <strong>the</strong> start <strong>of</strong> <strong>the</strong> preloaded movement. A START is ignored if it occurs be<strong>for</strong>e<strong>the</strong> preceding movement has been finished.10.7.3 Instruction STOPInstruction code : 12 (hexa : C).Data bytes :None.Answer byte :Status STATA.Tests :None.Interrupts <strong>the</strong> movement in progress. Braking is immediate. This instruction alsodesynchronizes a slave shaft. The acceleration value depends on <strong>the</strong> parameterASTOP. Status STATA evolves in <strong>the</strong> same way as <strong>for</strong> an ERUN (null-speed)instruction.10.7.4 Instructions EAMOV and PAMOVInstruction code : 7 and 6, respectively.Data bytes :1. Final position (msb).2. Final position (intermediate byte).3. Final position (lsb).Answer byte :Status STATA.Tests :None.These instructions execute or prepare <strong>the</strong> movement (acceleration, velocity,deceleration) towards <strong>the</strong> given final position (specified in LU units). This position canbe positive or negative.As soon as <strong>the</strong> final position is received, <strong>the</strong> distance to travel is converted intointernal units, and <strong>the</strong> movement or displacement direction is determined.The absolute reference is <strong>the</strong> motor position after <strong>the</strong> ST1 is powered up. It can bechanged to ano<strong>the</strong>r value at any time, using <strong>the</strong> instruction "INIABS".The absolute position only takes account <strong>of</strong> motion generated by <strong>the</strong> IRG : it ignoresmovements commanded by <strong>the</strong> master shaft.In <strong>the</strong> case <strong>of</strong> a long movement, <strong>the</strong> velocity pr<strong>of</strong>ile is trapezoidal; <strong>the</strong> velocitycorresponds to <strong>the</strong> current values <strong>of</strong> parameters CVP and RATE.In <strong>the</strong> case <strong>of</strong> a small movement, a lower velocity is calculated, and <strong>the</strong> velocity pr<strong>of</strong>ileis almost triangular.104
