 05 Multi-step control mode 4
The speed curve is the same as multi-speed step mode 3, but the speed switch signals are
level trigger. In this mode, it can switch speed without detecting speed switch limit to run to the
door close complete position after power on again.
 Comparison Table
Advantage Disadvantage
00 Distance
control mode 1
Uses PG signal to distinguish the
position for speed switch without
sensor.
It depends on PG signal highly. It will
cause pulse loss or wrong position for
speed switch when getting error PG
signal.
01 Distance
control mode 2
Uses PG signal to distinguish the
position for speed switch without
sensor and control output frequency
precisely.
It will cause incorrect output frequency
due to inaccurate PG feedback signal
or low PG resolution.
02 Multi-step
control mode 1
Uses four multi-input signal for
switching 16-step speed. That means it
has 16-step speed for single direction.
It needs to have sensor and external
controller to distinguish operation
direction.
03 Multi-step
control mode 2
Uses three multi-input signal and
operation direction for switching 16-
step speed, It doesn’t need external
controller to distinguish operation
direction.
It needs to have sensor. To compare
with “02 multi-step control mode 1”, it
only has 8-step speed for the single
direction.
