1. This fault does not affect motor auto-
tuning and commissioning at inspection
speed.
2. The HOP indicator is OFF at this fault.
Press
on the operation panel to hide the
fault display. Then, you can perform inspection at
inspection speed.

1. The elevator cannot run. You need
to rectify the fault rst and then perform
commissioning at inspection speed.
2. The fault cause may be: The feedback
inputs of both up and down slow-down
switches 1 are active; feedback inputs of
both up and down limit switches are active
simultaneously.
1. Terminals X14 and X15 are connected to
the slow-down switches 1 (NC input). Observe
whether the signal indicators of both X14 and
X15 are OFF. Check whether the slow-down
switches 1 are connected to X14 and X15 and
act properly.
2. Terminals X12 and X13 are connected to the
up and down limit switches (NC input). Observe
whether the signal indicators of both X12 and
X13 are OFF. Check whether the limit switches
are connected to X12 and X13 and act properly.
6.1.3 Commissioning at Inspection Speed
§
Safety Precautions
Ensure that all installation and wiring comply with the electrical safety specications before
commissioning at inspection speed.
During auto-tuning involving car, pay attention to the running direction of the motor and prevent the
elevator from getting too close to the terminal oor. You are advised to run the car to the oor far
away (for example, more than 2 oors away) from the terminal oor, and then perform commissioning.
For certain cabinets, "emergency electric RUN" is used instead of "inspection RUN". Note that
"emergency electric RUN" shorts certain safety circuit in the shaft, and you need to pay more
attentions to the safety when the car runs close to the terminal oor.
● The motor may rotate during auto-tuning. Keep a safety distance from the motor to prevent personal injury.
● During with-load motor auto-tuning, ensure that there is no person in the shaft to prevent personal injury or
death.
Commissioning at inspection speed includes motor auto-tuning and running test at inspection speed.
Learns motor parameters and encoder
angle (synchronous motor)
1. Check that the motor running direction is correct.
2. Check that motor running current is proper.
3. Check that inspection on top of the car takes precedence
over inspection in the equipment room.
4. Check that the shaft is unobstructed, without any obstacle.
