Cd Operation Curve For Distance Control - Emerson EV3200 User Manual

26 Chapter 6 Parameter Description
2. Timing begins when CD starts. When the CD start creep
time (F2.00) is over, the inverter starts to operate at CD
reference frequency (F2.04), and accelerates according to
CD Acc time (F2.03), and then operates at high speed after
the acceleration.
3. When the CD speed decrease signal is active, the
inverter decelerates within CD Dec time (F2.07) to CD
ending creep speed (F2.08), and operates at constant
ending speed in low-speed section when deceleration is
over.
4. When CD position limiting signal is active, the inverter
continues to run at CD low speed, and the inverter judges
the output torque. If the torque is bigger or equal to the
threshold of CD torque changing (F2.10), the inverter will
keep the CD torque of F2.11, thus the whole CD process is
over.
5. When OD command is cancelled, the inverter will not
maintain the OD torque any more.

6.3.2 CD Operation Curve For Distance Control

The operation curve parameters in group F2 related to
distance control should be set correctly.
Door width auto-learning should be implemented before
distance control. The CD speed curve of distance control is
illustrated in Figure 6-9.

Figure 6-9 CD operation curve for distance control
CD process of distance control 1:
1. When the CD command is active, the inverter starts at
start creep speed (F2.02), and then operates at constant
speed in low-speed section.
2. When reaching D1, the inverter starts to operate at CD
reference frequency (F2.04), and accelerates according to
CD Acc time (F2.03), and then operates at high speed after
the acceleration.
3. When reaching D2, the inverter decelerates within CD
Dec time (F2.07) to CD ending creep speed (F2.08), and
operates at constant ending speed in low-speed section
when after the deceleration.

4. When reaching D3, the inverter will run at the CD speed
after door locking point (F2.16), speeding up the CD
process.
5. When reaching D4, the inverter continues to run at CD
speed after door locking point. If the output torque is bigger
or equal to the threshold for CD torque changing (F2.10),
the inverter will maintain the torque of F2.11, thus the whole
CD process is over.
5. When CD command is disabled, the inverter exits the CD
torque maintaining status.
F2.00 CD start creep time for
speed control
Defines the duration the inverter operates at start creep
speed in CD process under speed control.
F2.01 CD start creep
distance
In CD process under distance control, the pulse number is
recorded in real time. When the pulse number is bigger or
equal to the product of F2.01 and the door width, the
inverter switches from CD start creep speed (F2.02) to CD
high speed (F2.04).
F2.02 CD start creep speed
Defines the low operating frequency (speed) in CD process.
F2.03 CD Acc time
Defines the time taken for the inverter to accelerate from the
CD start creep speed to the CD frequency.
Time
F2.04 CD reference
frequency
Defines the high operating frequency (speed) in CD
process.
F2.05 Rush hour
operation CD speed
When the rush hour operation signal is active, this
parameter defines the frequency (speed) the inverter
operates at high speed in CD process, or the running
frequency in the general-purpose inverter mode.
F2.06 CD speed decrease
point in distance control
In the CD process under distance control, the pulse number
is recorded in real time. When the pulse number is bigger or
equal to the product of F2.06 and the door width, the
inverter will switch from CD high speed to CD ending creep
speed.
