Installation and Connection
Selection of the supply voltage
15 V
24 V or external
supply via the
control control card
The maximum load capacity is dependant on the selected voltage supply.
Max. load capacity with 15V internal supply: 300 mA
Max. load capacity with 24 V internal supply:170 mA
Max. load capacity with an external 24V supply 1 A (dependent on the
external voltage source)
The specified currents are reduced by any current drawn on the second
interface X3B.
Note: For 5V TTL encoders, a 5V supply is available on second interface,
X3B terminal 7.
For maximum noise immunity, the encoder cable shall consist of individually
shielded twisted pairs with one overall shield. The individual shields should
be connected to 0V (com) pin 8 on the X3A terminal strip and be kept
electrically isolated from the outer shield. The outer shield should be
connected to earth ground on the elevator drive.
The cable shall be kept a minimum of 8 inches (20 cm) away from all
wires having greater than 24VDC on them. For best results run the
encoder cable in a separate conduit from the controller to the motor.
