1. According to the preceding gure, set these parameters according to the requirement:
V1 (F4-17) ≥ V2 (F4-18), T1 (F4-19) ≤ T2 (F4-20)
2. The torque threshold for judging door close hindered is curve 1 shown in the gure. The
shadow part shows that door close hindered occurs.
Group F5: Door Open/Close Auxiliary Parameters
Function Code Parameter Name Setting Range Default Min. Unit
F5-00 Abnormality deceleration time 0.1–5.0s 0.3s 0.1s
It is used to set the time for the system to decelerate from the door close speed to zero speed
when door close is hindered. Set this parameter to the minimum value as possible when
ensuring that overcurrent does not occur during deceleration.
Function Code Parameter Name Setting Range Default Min. Unit
F5-01 Door open time limit 0–999.9s 30.0s 1s
It is used to limit the door open time. If the controller does not receive the door open limit signal
(pulse loss occurs in distance control mode) within the time, it performs door open timeout
protection (Er28).
This parameter is invalid when it is set to 0.
Function Code Parameter Name Setting Range Default Min. Unit
F5-02 Door close time limit 0–999.9s 0s 1s
It is used to limit the door close time. If the controller does not receive the door close limit
signal within the time, it determines that door close is hindered, and performs door re-open or
zero speed holding based on the setting of F4-14.
This parameter is invalid when it is set to 0.
Function Code Parameter Name Setting Range Default Min. Unit
F5-03 Low speed running time limit 0–999.9s 0s 1s
