Eshine YS-K01 - CD Curve Optimal

OD holding: After door creeps through the OD limit point (P3.07), it will output the OD arrival
signal. When door torque＞OD switching torque (P5.00), it will switch to OD torque holding state.
After some time the door is in the fully open state, then switch to a small torque holding state, which
can save energy and prevent motor from heating to ensure that the door has certain open tension.
5.3.2 CD Curve Optimal
A full itinerary CD curve has five stages: CD start, CD high-speed run, CD creep, door blade action
and CD holding. According to the Figure 5-3 we can set reasonable parameters to achieve the
desired CD effect.
Figure 5-3 Relationship of CD curve and curve parameters
CD start: The CD starts to run at start speed (P4.01).
In order to improve the CD efficiency, generally cancel the startup state and directly accelerates to
the CD speed (P4.03) to enter into high-speed run state. Just as Figure 5-4.
Figure 5-4 Optimum CD startup curve
CD high-speed run: After CD startup ends, CD will accelerate from CD start speed (P4.01) to CD
speed (P4.03). The run speed will not decelerate to creeping speed (P4.06) until it run to Dec point
(P4.04).
CD creep: Before CD position arrives, to prevent door board and door blade from collision damage
caused by high speed, the door should slow down to creeping speed to run.
Door blade action: From CD process to two door boards close state, a short time relative higher
than creeping speed (P4.08) is needed to achieve door blade action safe and reliable as soon as
possible, while it can improve the CD efficiency.
