Related Parameters
Parameter
No.
Parameter Name Setting Range Default Description
F2-32
Torque output
duration
1 to 10s 5
When it is set to 0, the system uses the
default value 5.
F2-33 Torque limit
1 to 150% rated
motor torque
110
When it is set to 0, the system uses the
value 80% of rated motor torque. The default
value is 110%.
F2-34
Threshold of pulses
for judging braking
force abnormal
1 to 100 encoder
feedback pulses
0
When the torque reaches a constant value,
the system starts to detect the pulse change
of the encoder in real time. If the pulses
exceeds the threshold set in this parameter,
the system considers that the braking force
is abnormal.
When it is set to 0, the system uses the
value 30.
F2-35
Threshold of slip
distance excessive
1° to 20° motor
rotating mechanical
angle
0
The system detects whether the slip distance
is excessive in the entire process. When the
slip distance exceeds the threshold set in
this parameter, the system blocks the output
immediately.
When it is set to 0, the system uses the
value 20°.
F-8 Test function
8: Manual detection
of braking force
0
The braking force detection is enable by
setting the keypad.
F7-09
Braking force
detection result
0: No operation
1: Qualied
2: Unqualied
0 /
F7-10
Countdown of braking
force detection period
0 to 1440 1440
It automatically restores to 1140 after
becoming 0.
1. Manual detection
Conditions:
• The system is in inspection state (inspection switch is turned on).
• The elevator is within door zone, with door locked.
Procedure:
1) Set F-8 to 8 on the keypad.
2) The system enters the test state, and the keypad displays “E88”.
3) The shorting PMSM stator contactor and RUN contact have output, and the brake contactor has
no output.
4) The system outputs torque based on the braking force parameters and starts the test.
5) When the keypad display “E88” disappears, the test is completed. The operating panel displays
the test result in F7-09. If F7-09 = 2, the keypad prompts E66 immediately, indicating braking
force unqualied. In this case, the elevator stops running. Fault E66 cannot be reset.
2. Automatic detection:
After judging that the braking force detection conditions are met, the system automatically enters the
