Digital VVVF Synchronized Door Operator Installation to put key , the operation direction is door close direction. If the direction is reverse “-”or “-” failure can be indicated, now you can change the value of A4. 5.To make sure the pulse direction Observation should be done during the door operation. If the door is opening the pulse-indicating digit value on panel should increases and decreases if the door is closing. Otherwise will indicate “-”or “-”failure. Set value of A3 should be changed. 6.To regulate the slow-speed door open/ close V/F curve（attached electric diagram 2 ） To set A101 and put key to make the door whole-stroke open twice. If there is “-8” failure showing the slow-speed moment is not enough. You could increase U1、 U2、 E2、 E4 appropriately to make sure that the door can open smoothly in the whole stroke. To put key and make the door whole-stroke close twice. If there is “-7” failure showing the slow-speed frequency is too low. You can increase E6 appropriately to make sure that the door can close smoothly in the whole stroke. For the side opening of huge door and four-panel center opening door, you can increase the output moment and slow-speed frequency appropriately. Generally U1 and U2 can increase 35, E2、 E4、 E6 increase 24 to resist larger mechanical resistant force. 7.To regulate the door-open holding force To lift the elevator to leveling position, and make the door skate closes the landing door，to set A101，to make the door the any unclosed position by key or . If the door can be kept static you can turn to next step. Otherwise to regulate E7 and U1 until the door stops and doesnt move in unclosed condition. If the door moves to the opening direction showing the door-open holding force is over-large. You can decrease U1 or E7(usually U1); If the door moves to the closing direction showing the holding force is not enough, you can increase U1 or E7 (usually U1). U1 must be small than U2, U3 and U4. Otherwise the system will report failure. 8.Self-tuning 8.1 To set L201 and quit the parameter set. The door operator self-tuning begins. 8.2 First the system close the door as per the frequency set through E2 and indicating pulse decreases. When the door is fully closed the initial value should be set as 0. 16 Attention：1.If the operation direction of door is reverse, to regulate the phase turn of electric motor. Namely to alter the parameter A4. 2.If the door doesnt move, to check the plug of electric motor is inserted tightly. 3.If the door stops without full closing, to check the connection of coder. 4.If the indicating pulse increases during door closing, to regulate the phase turn of coder, namely to alter the parameter A3. 5.If the position of door skate is wrong after door close, to check the installation of door skate and the regulation of rubber bolt. To check if the hinged plate is leaning on the middle buffer rubber. 6.If the gate can not be fully closed, to check if there is any mechanical failure. 8.3 Then the system will open the door as per the frequency set through E2.The indicating pulse increases. The pulse digit value will be memorized as the door width in EEPROM permanently after the door is fully opened. At the same time the operation curves for gate open and close will be computed automatically. Self-tuning is ended. L2 is auto-set as 0 without manual alteration. Attention: If the door can not be fully opened 1.To check the mechanical installation and make sure the door is not blocked and the output moment is larger than the resistant moment. 4.6 could be reference. 2.To check the cable connection and installation of coder. If the indicating pulse decreases, to alter A3. 8.4 If there is any abnormal conditions during self-tuning it can be stopped by key . And the learning can be restarted after the problem is solved. 9.To test operate and observe the operation condition. To set A102 for manual panel door-closing. To put key or ，the door will open or close continuously until to the end. The operation is stopped by key . According to the operation of door operator, to regulate the slowdown points（parameters of group F） ,frequency parameters（parameters of group E） and time parameters（parameters of group C） to meet your requirement. 17 If there is obvious impact when the door is fully closed If the speed is obviously slow down when the door is fully closed To increase the door-closing deceleration pulse F1 To decrease the door-closing deceleration pulse F1 To decrease the door-closing deceleration time C6； To increase the door-closing deceleration time C6； To decrease the door-closing frequency E5； To increase the door-closing frequency E5； If there is obvious impact when the door is fully opened If the speed is obviously slow down when the door is fully opened To increase the door-opening deceleration pulse F2 To decrease the door-opening deceleration pulse F2 To decrease the door-openin
