Acceleration/Deceleration Section 7-6
• The following operating data area settings are used:
• Position
• Speed, V
1
(pps)
• Acceleration time, Ta (ms)
• Deceleration time, Td (ms)
Note If override is enabled (i.e., the Override Enable Bit is ON), the speed will be as
follows:
Speed = Operating data area’s speed setting
×
Operating data area’s override
setting
÷
100.
7-6-2 Calculating Accel/Decel Times for Continuous Positioning
The actual acceleration and deceleration times when a command for a new
positioning operation is made during direct operation can be calculated in the
way shown below.
Case 1: Speed for the Next Positioning Operation is Faster
