- 112 -
It is used to set encoder signal verication. This parameter is set by the manufacturer, and
you need not modify it generally.

F1-11 Auto-tuning mode
0: No operation
1: With-load auto-tuning
2: No-load auto-tuning
3: Shaft auto-tuning 1
4: Shaft auto-tuning 2
0 - ★
It is used to select the auto-tuning mode.
1: With-load auto-tuning
It is static auto-tuning for the asynchronous motor (the motor does not rotate) and rotary
auto-tuning for the synchronous motor (the brake is released and the motor rotates).
2: No-load auto-tuning
The motor must be completely disconnected from the load; otherwise, the auto-tuning effect
will be affected. When "TUNE" is displayed on the operation panel, you need to manually
release the brake before starting auto-tuning.
3: Shaft auto-tuning 1 4: Shaft auto-tuning 2
These two modes are similar, except that shaft auto-tuning 1 reserves the leveling
adjustment records in group Fr, and shaft auto-tuning 2 clears these records.

F1-12 Encoder pulses per revolution 0–10000 1024 PPR ★
It is used to set the pulses per revolution of the encoder (according to the encoder
nameplate).
This parameter is critical to CLVC. Set the encoder nominal value in this parameter.
Otherwise, the elevator may not run properly. When the feedback pulses received by the
system is data after frequency division by other equipment, set the frequency-division value
rather than the encoder nominal value in this parameter. For example, if the pulses per
revolution of the encoder is 8192 and is sent to the system after 1/4 frequency division, set
this parameter to 2048 (8192/4 = 2048).
F0-04 (Rated elevator speed), F1-05 (Rated motor rotational speed), and F1-12 (Encoder
pulses per revolution) determine whether the elevator can run properly. If any of these
parameters is changed, shaft auto-tuning must be performed again.

Encoder wire-breaking
detection time
0–10.0 1.0 s ★
This parameter is used to set the time that a wire-break fault lasts before being detected.
After the elevator starts running at non-zero speed, if there is no encoder signal input within
the time set in this parameter, the system prompts the encoder fault and stops running.
When the value is smaller than 0.5s, this function is disabled.
