The motor should be connected to SDK-500 using shielded 2-wire cable. Make sure that
shield is connected properly to GND at one end only. Leaving shield disconnected may cause
excessive EMC noise. See chapter First power-on on page 29 to check the order of wire
connections.
3.5. ENCODER
A)
J4
The controller is designed to work with motors equipped with 5V quadrature encoders,
generating from 150 to 999 pulses per centimetre of door's linear movement. Typically
encoder cables are terminated with a Canon DB-9 connector. The SDK-500 has a DB-9 socket
on board in order to facilitate fast and convenient installation. (Figure 3.4 A).
CAUTION! Make sure that encoder signal pins match SDK-500 encoder
connector to avoid damage to the controller.
If the encoder cable is not terminated with Canon DB-9 connector, the encoder can be
connected directly to the SDK-500 board's screw terminals as shown in figure 3.4B.
3.6. CONTROL INPUTS
The SDK-500 controller is equipped with two control inputs provided for compatibility with
different types of elevator controllers. Both inputs or either of them individually can be
activated from the menu of the controller. Connection alternatives are shown below.
Figures 3.5 A and B shows how to connect open/close control signals to {CLOSE INP.}
and {OPEN INP.} inputs of the SDK-500 . The control signals are generated by the main
controller of the elevator. If the elevator control system uses normally-open potential-free
contacts (e.g. relay) to control the doors they can be connected to SDK-500 as shown in fig.
3.5A utilising the on-board voltage source of the controller. If the elevator control system uses
voltage outputs to control doors, they can be connected to SDK-500 as shown in fig. 3.5B.
Make sure that both inputs are activated in the controller's menu.
