4.4.2 Distance Control Mode
1. The encoder needs to be installed for this mode. The controller judges the door position
based on the encoder signals. The door width pulses need to be identied at rst-time running.
The controller decelerates and judges door open/close limit based on the door open/close
curve.
The following gure takes Inovance elevator control system to describe wiring of the relevant
signals.

2. Check the encoder.
The pulse signal from the encoder is critical to accurate control of the system. Before
commissioning, check the following items carefully:
1) The encoder is installed reliably with correct wiring.
2) The signal cable and strong-current circuit of the encoder are laid in different ducts to
prevent interference.
3) The encoder cable is preferably directly connected to the controller. If the cable is not long
enough and an extension cable is required, the extension cable must be a shielded cable
and preferably welded to the original encoder cable by using the soldering iron.
