Table 4.14 Pin assignment for the connector X7
4.13.5 Connection for high-resolution encoders
The interface X7 makes possible the evaluation of the following encoder types.
Table 4.13 Suitable encoder types on X7
NOTE:
• T
he usage of encoders not included in the range supplied by Moog
requires special approval by Moog.
• T
he maximum signal input fr
equency is 500 kHz.
• E
ncoders with a
power supply of 5 V ±5 % must have a separate sensor
cable connection. The sensor cable detects the actual supply voltage at
the encoder; it is then possible to compensate for the voltage drop on
the cable. Only by use of the sensor cable is it ensured that the encoder
is supplied with the correct voltage. The sensor cable must always be
connected.
Select the cable type specified by the motor or encoder manufactu er. During this
process bear in mind the following boundary conditions:
•
Always used shielded cables. Connect the shield at both ends.
•
Connect the differential track signals A/B, R or CLK, DATA using twisted pair
cable cores.
