Parameter Name Setting Range Factory Setting Unit Operation
F0-04
Maximum braking-
to-stop distance
0.20–1.69 0.5 m ★
The upper limit and lower limit of this parameter are controlled by F0-01 (Nominal speed).
If the system detects that the braking-to-stop distance exceeds 1.2 times of the setting of
F0-04, the system reports the braking-to-stop over-distance fault.

F0-05
Handrail pulse time
interval at nominal
speed
0.01–5.00 0.68 s ★
It is used to set the time interval between handrail pulses at nominal speed. The system
detects whether the handrail speed is consistent with the escalator speed based on the
nominal speed, the setting of F0-05 and the actually detected escalator speed.
For example, the nominal speed is 0.5 m/s and F0-05 is set to 0.10s. When the actually
detected escalator speed is 0.4 m/s, the time interval between handrail signals should be 0.5
x 0.1/0.4 = 0.125s. If the actually detected time interval between handrail signals is longer
than 0.125s, it indicates that the handrail is slow. If the detected handrail speed remains
15% slower than the escalator speed for 15s, the system reports the related fault.

F0-06
Upper limit of phase
A/B pulses between
two step signals
- 0 - ★
It is used to set the upper limit of phase A/B pulses between two step signals. For every
step the escalator turns, the number of teeth of the driving chain sprocket counted by the
sensor is fixed.
After you set F0-06 to 0 first, the system automatically calculates the number of phase A/B
pulses between two step signals and saves it. Then you can set the upper limit of phase A/
B pulses between two step signals according to the following principle:
If the automatic calculation value is A, it is suggested to set 2 times value 2 x A limitation
for F0-06.

F0-07
Lower limit of phase
A/B pulses between
two step signals
0 to F0-06 0 - ★
It is used to set the lower limit of phase A/B pulses between two step signals and should be
a litter smaller than the automatic calculation value of the system.
For the escalator, it is mainly used to filter the incorrect signal that may arise (for example,
interference) between two adjacent step signals.
For the moving walkway, the value of F0-07 should be larger than the number of phase A/B
pulses between the detected beams of two adjacent pallets (for example, beams X and Y
in Figure 3-7). Otherwise, the system will report fault Err12.
