Enhance the Riding Confort of Elevator
If there is any uncomfortable feeling during acceleration and deceleration period when you take the elevator.
Please try to adjust the parameters as follows.

Notes：
During the deceleration of S curve, if the output frequency is lower than 01-08, the function of S curve will be
stopped and then transfer to DC injection braking (Zero Speed Control).

Note 1：
According to the standards of European market, when the elevator is stop, the inverter and the motor has to be
separated by contactor. For emergency situation, the inverter and the motor just can be separated by DC injection
braking disabled and base block enabled (base block signal is ON)
Note 2：
When inverter control is separated from motor control or DC injection braking control (Zero speed control).
Sometimes, inverter will occur fault by pulse voltage.
Besides, when the contactor is installed between inverter and motor, please et 08-10=1 (Selection of output phase
loss protection).
