CHV180 series frequency inverter special for elevator Appendix A
.111.
Appendix A: Commissioning guide
A.1 Runing and parameter-adjusting
After setting application parameters, the parameters should be checked according to
function requirement, especially the parameters that are interrelated to peripheral
wiring of inverter, such as operation mode, control mode, setting of programmable
input/output and selecting of feedback quantity. If there is no mistake, debug system
running. Debug running includes motor parameters autotuning, overhaul running,
S-curve adjusting of good running, comfortable adjusting of elevator on-off and
precision adjusting of elevator flat bed.
A.1.1 Motor parameters autotuning
Before beginning to debug elevator, it is recommended that user should carry out
tractor parameters autotuning. During autotuning, the motor should be unloaded, the
keypad control mode is selected (P0.01=0), and carry out parameter autotuning
according to the description of P0.08.
Note: It is different between the motor parameters autotuning of synchronous
motor and asynchronous motor.
A.1.2 Overhaul running
Overhaul running is used to judge whether the elevator is in good running.
During overhaul running, attention should be paid to whether actual running direction
of elevator is in accordance with instruction direction, if they are inconsistent, change
any two wirings of the output terminal (U,V,W), or adjust P0.06 to be 1.
Note: Because the parameters should be re-autotuned after changing the motor
wiring for synchronous motor, so it is recommended that the user changes
elevator running direction by adjusting P0.06.
A.1.3 S-curve adjusting
Before runing, verify that whether the control logic and wiring are right. If they are right,
carry out the adjusting of S-curve. Refer to the description of P1.08~P1.15.
A.1.4 Comfort adjustment during the stopping/starting of the elevator
Set the following parameters to change the comfort of elevator starting: P1.14 (starting
speed), P1.15 (holding time of starting speed), P1.08 (starting quadric acceleration),
P1.09 (starting acceleration), P3.00 and P3.01 (PI parameter of low speed), P8.06
(contracting brake open delay time). If weighing equipments of analog quantity are
used, it is necessary to adjust pre-torque compensation of starting moment. Please
refer to each function code to carry out adjusting.
Set the following parameters to change the comfortable of elevator stopping: P1.12
