Loading the ramp function generator
When bLoad is set to TRUE, the ramp function generator is loaded with the signal at nSet_a. This
value is accepted immediately and output at nOut_a. There is no acceleration or deceleration via an
S shape. As long as bLoad = TRUE, the ramp function generator remains inhibited.
Acceleration/Deceleration time and S-ramp time
The acceleration/deceleration time and the S-ramp time for jerk-free acceleration can be set
separately.
• Acceleration/Deceleration time = Time until the nOut_a output value has reached the nIn_a
input value.
• S-ramp time = Time until the ramp function generator operates at maximum acceleration.
