adjustment parameters F229 ~ F231, the inverter calculates the final actual torque compensation
value and makes starting compensation. Therefore, in this case, it is necessary to adjust the three
parameters F229 ~ F231.
First, adjust the compensation offset parameter F231. Load the lift car to the balance load,
run the lift car to the middle position, and then confirm that the lift car is in complete balance with
its counterweight (after powered off, with the brake released, the lift car can remain completely
motionless). Set the Inspection speed F12 to 0, adjust the parameter F231 so that the elevator can
remain completely motionless in Inspection operation.
Then, confirm whether the compensation direction is correct: Leave the lift car stop
no-loaded at the leveling position of any floor in the middle, if the decrease of F230 (compensated
gain) may reduce the upward impact oscillation of the lift car at start (slipping back when start
downward or rushing when start upward), it means the compensation direction is correct;
otherwise, it means the compensation direction is wrong. If wrong, change the value of Parameter
F229 (from 0 to 1 or from 1 to 0)
After confirming the compensation direction, you can finally adjust compensation gain
parameter F230. Run the no-load lift car to the leveling position of the top floor, set the Inspection
speed (F12) to 0, adjust the compensation gain parameter F230 (if the lift car moves upward at
start, decrease this parameter; if downward, increase this parameter, until the lift car does not
motion when the Inspection starts.
8.10.3 Simple compensation by using light-load and heavy-load
switch (F164 set to 4)
AS380 integrated elevator dedicated drive controller adopts pre-load starting compensation
with weighing device and another simple starting compensation: by using light-load and
heavy-load switch. With this starting compensation, Encoder can adopt 8192 pulse A, B, Z phase
incremental Encoder, and does not need accurate weighing devices but simply installs two
micro-switches on the car bottom. For synchronous gearless tractor elevator, high resolution SIN /
COS Encoder is mandatory for a no weighing starting compensation mode. Compared with A, B,
Z phase incremental Encoder, SIN / COS Encoder is more expensive with more wiring and
weaker to interference. So, compared with no weighing starting compensation mode, the
light-load and heavy-load switch starting compensation is less expensive, with less wiring and
stronger to interference. Compared with pre-load starting compensation with analog signal input,
it is less expensive, easier to be installed and simpler for commissioning due to the absence of an
accurate weighing device. Therefore, we recommend the light-load and heavy-load switch starting
compensation mode to the customers who use the dedicated drive controller of AS380 integrated
elevator.
When the light-load and heavy-load switch starting compensation mode is adopted, it is
necessary to install a light-load and a heavy-load switch on the car bottom. We recommend that
the light-load switch motions when the lift car load is less than 25% of the rated load, while the
heavy-load switch motions when the lift car load is greater than 75% of the rated load. The
light-load switch can be connected to JP6-02 (HX4) of (SM-02H) on the car top board, while the
heavy-load switch can be connected to JP6-03 (HX5) terminal of (SM-02H) on the car top board.
