5.8 DDC Instructions
5.8.12 Linear Accelerator/Decelerator 2 (SLAU)
5-186
ΠIf QS (quick stop) is opened, QT (quick stop time) is used as the acceleration/deceleration time.
[ b ] Parameter Table Configuration for SLAU Instruction with Double-length Integers
∗ 1. D is a double-length real number expressed in four words. The MPE720 cannot display this value as a real number.
∗ 2. The relay input and output bits are assigned as given below. (Close = Bit change to 1 (ON), Open = Bit change to 0
(OFF))
ΠIf QS (quick stop) is opened, QT (quick stop time) is used as the acceleration/deceleration time.
