1.GDB car door
1.1 Close the door in place have a voice
A:(1)Check whether closed in place when the door between the seam is too small (buffer does not play a role in the door)
  (2)In ensuring the door cam can under the condition of normal away, reduced speed closed in place U6, increase deceleration position I6 and I7 slowdown in advance.

1.2 The speed of the door in place is slow, door cam can't tuck
A:(1)Check the resistance of landing door and car door,if too much resistance refer to mechanical problems 2.
(2)In the case of door plank not bump, the appropriate closed in place U6 speed, reduce the deceleration position I6 and I7 to delay the slowdown.
1.3 Open closed high-speed period of too fast or too slow
A:(1)When opened the door ,too fast shutter speed U2 ,slowly increase the shutter speed U2
   (2)When closed the door ,too fast decrease U5 closing speed ,The slow increase U5 closing speed
1.4 Open the door in place a sound
A:In ensuring the door can be open in place, appropriate U3, down to open the door in place close to the speed reduce slow position i2 and I3 slowdown in advance.
1.5 Open the door in place is slow, unable to open in place
A:(1)Check the car door resistance hall, too much resistance refer to mechanical problems 2
   (2)In the case of door plank not bump, appropriate up to open the door in place close to the speed U3, increase deceleration position i2 and I3 to delay the slowdown.
1.6 Other operation problems
A:After power to the half open door closed, hold down the electricity recovery factory Ctrl# button again (If necessary, please record the values of the parameters required for reset ),"-..." loosen ,Door wide self learning, according to value + button to close the door, after putting in place to open the door ,in the process of open display Numbers increased slowly ,open the door in place after the show "100",to complete the door wide self learning 。
The possible problems in the learning process:
(1)After press the value + shows "S -", check the motor line (e.g., the problem to replace the motor), check the port output voltage 310 v motor (such as the problem to replace converter), check the encoder signal input light L12 and L13 whether in open and close alternately flashing (replace encoder).
(2)First open the door, after press value + motor UVW connection error, will be three phase motor UVW any two in each other.
(3)In the process of open display digital garbled words, encoder AB phase error, will change each other AB.

2. GDO - D2 and GDO - D3  car door
2.1 Close the door in place have a voice
A:(1)Check whether closed in place when the door between the seam is too small (door of cushion cushion)
  (2)In ensuring the door knife can under the condition of normal away, closed down in place appropriate speed U11 and closed the door knife U12, increase deceleration position I9 and I10 slowdown ahead.
2.2 Shut the door in place is slow, door knife to assemble
A:(1)Check the car door resistance hall, too much resistance refer to mechanical problems 2
   (2)In the case of door plank not bump, up close in place appropriate speed U11 and closed the door knife U12, reduce the deceleration position I9 and I10 to delay the slowdown.
2.3 Open closed high-speed period of too fast or too slow
A: (1)When opened the door, too fast shutter speed U2 and U3 , Slowly increase the shutter speed U2 and U3
   (2)When closed the door,closed too quickly reduce speed U9 and U10 ,the slow increase U9 and U10 closing speed
2.4 Open the door in place a sound
A:In ensuring that the door can be open in place, appropriate U5 and U6 down to open the door in place close to the speed, reduce the deceleration position i2 and I5 slowdown ahead.
2.5 Open the door in place is slow, unable to open in place
A:(1)Check the car door resistance hall, too much resistance refer to mechanical problems 2   (2)In the case of door plank not bump, appropriate up to open the door in place close to the speed U5 and U6, increase deceleration position i2 and I3 to delay the slowdown.
2.6 Other operation problems
A:After power to the half open door closed, hold down the Ctrl# button again to electricity to restore the factory values (if necessary, please record the values of the parameters for resetting), appear "-..." Loosen, door wide self learning, according to the value + button to close the door, put in place to open the door, display Numbers increase slowly, in the process of open the door to open the door in place after the show "100", to complete the door width self learning.
The possible problems in the learning process:
(1)After press the value + displays "EN", check the motor line (e.g., the problem to replace the motor), check the port output voltage motor (such as the problem to replace converter), check the encoder signal input light L18 and L19 whether in open and close alternately flashing (replace encoder).
(2)After press the value + open the door first, electrical wiring error, the motor power line connection swap.
(3)In the process of open display digital garbled words, encoder AB phase error, will change each other AB.

3.GDK car door
3.1 Close the door in place have a voice
A:(1)Check whether closed in place when the door between the seam is too small (door of cushion cushion)
  (2)Inspection door 104 if appropriate, to ensure the door knife can under the condition of normal away, appropriate closed down in place of nearly 308, speed 308 and closed the door knife more closed in place close to the distance of 323.
3.2 Shut the door in place is slow, door knife to assemble
A:(1)Check the car door resistance hall, too much resistance refer to mechanical problems 2
   (2)Inspection door 104 whether appropriate, in the case of door plank not bump, the appropriate closed in place close to the speed of 308 and closed the door knife speed 310, reduce closed in place close to the distance of 323.
3.3 Open closed high-speed period of too fast or too slow
A:(1)when opened the door,too fast shutter speed 302 ,slowly increase the shutter speed, 302
