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.
The same rule applies to Y11.
e) Once the instruction is activated, all other parameters cannot be modified until the instruction is disabled.
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.
