Note: In the guarantee of elevator operation efficiency, adjust the 6 parameters of curve slope
appropriately to obtain best elevator operation curve when debugging in the actual situation.
To achieve the maximum level of comfort, integrated controller must control the motor and
make feedback speed strictly following the change of running curve.
Proportional gain on the speed circle F6-04 and integral gain F6-05 or F7-05~F7-12 for PI section
parameters also influence the motor tracking ability to speed curve. Generally, increasing the
proportion gain will improve the reaction of the system and promote the tracking speed. However, if
proportion gain is set too big, it will cause system vibration with high frequency and large motor
noise. Increasing integral gain can improve the system anti-interference/tracking ability and improve
the leveling precision but set integral gain too big will make system vibration, speed over adjustment
and wave vibration.
Generally, it is recommended to first adjust proportion gain, increase it right before system
vibration threshold. Then adjust the integral gain, enable system with quick reaction and no over
adjustment.

Speed loop proportional/integral can be adjusted in 50 increments. If system performance is not
perfect at start or stop period (low speed period), try to control in multi-section PI. Detailed method
in description section of specific section is in instruction.
