7.3 Wiring between Elevator Controller and Inverter
There are two kinds of wiring between elevator controller and
-S3 Inverter: One is
between elevator controller output signal and the Inverter, including upward and
downward commands, enabling signals and speed-giving commands; the other is
between Inverter output signal and elevator controller, including running signal (indicating
Inverter ready to work), fault signals and encoder pulses processed by PG card. Since
there are three speed control modes, each with a slightly different wiring, these are
separately described in the following three sections with figures for reference. Different
types of PG card also shows different wiring with encoder signals, and the examples in the
following figures are different. Refer to 4.5 Wiring of PG Card.
7.3.1 Analog Voltage Control Mode
In analog control mode, control through analog voltage is the most common method. The
wiring is shown in Figure 7.2.
