9 Application Instructions API 150-199 b) Settings of absolute positioning and the acceleration/deceleration speed: D1343 (D1353) is for settings of the time of the first acceleration segment and last deceleration segment of Y10 (Y11). D1340 (D1352) is for settings of start/end frequency of Y10 (Y11). Acceleration sampling time Output pulse frequency Acceleration slope First acceleration segment Y10 (D1340) Y11 (D1352) Min: 100Hz Last deceleration segment Y10 (D1340) Y11 (D1352) Min: 100Hz accel/decel time accel/decel time Current position Default: 200ms Y10 (D1343) Y11 (D1353) Default:
200ms Y10 (D1343) Y11 (D1353) Output pulse numbers c) Many DRVA instructions can be compiled synchronously in the program, but only one instruction can be activated whenever the PLC executes the program. For example, if Y10 output has already been activated by an instruction, other instructions that are also used to activate Y10 output will not be excecuted. Therefore, the principle of the instruction activation sequence is “first activated, first executed”. d) When Y10 is activated by DDRVA instruction, the output function of Y10 will be disabled until DDRVAis OFF. e) Once the instruction is activated, all other parameters cannot be modified until the instruction is disabled.
The same rule applies to Y11. f) When the instruction is disabled but the output has not yet completed: M1334 = On indicates that Y10 will stop output immediately. M1334 = Off indicates that Y10 will decelerate according to the deceleration time till it reaches end frequency and stop the pulse output. M1335 corresponds to Y11 output and applies the same rule. 3. See remarks of DDRVI instruction for more details on the flags. DVP-PLC Application Manual 9-60
