Trapezoidal control Type 0 (F171)
- Specify the time from the initial speed to the target speed as acceleration time and the time from the
target speed to the initial speed as deceleration time in the program.
- Each section between the initial speed and the target speed, and between the target speed and the
initial speed is divided into the speed table of 30 steps to calculate the speed. Therefore, the
acceleration/deceleration is smoother compared to the trapezoidal control type 1.
- After the execution of the instruction, the speed can be changed within the range of the target speed.
To change the target speed to the one faster than the target speed right after the execution, select the
type 1..
Trapezoidal control Type 1 (F171)
- Specify the time from the initial speed to the maximum speed (50 kHz) as acceleration time and the
time from the maximum speed (50 kHz) to the initial speed as deceleration time in the program. The
actual acceleration/deceleration time is relatively shorter than the specified acceleration/deceleration
time.
- Each section between the initial speed and the maximum speed (50 kHz), and between the maximum
speed (50 kHz) and the initial speed is divided into the speed table of 30 steps to calculate the speed.
Therefore, the acceleration/deceleration is not as smooth compared to other control patterns especially
when the target speed is low. To use in a low-speed area with a device such as a stepping motor,
select the trapezoidal control Type 0.
- After the execution of the instruction, the speed can be changed within the range of the maximum
speed (50 kHz).
