Sin/Cos encoder with zero pulse
e.g. Heidenhain ERN1381, ROD486
Heidenhain Sin/Cos encoder with fully digital EnDat interface
e.g. 13-bit singleturn encoder (ECN1313.EnDat01) and 25-bit multiturn encoder
(EQN1325-EnDat01)
Heidenhain encoder with digital EnDat interface
Single or multiturn encoder
Sin/Cos encoder with SSI interface
e.g. 13-bit singleturn and 25-bit multiturn encoder (ECN413-SSI, EQN425-SSI)
Sick-Stegmann Sin/Cos encoder with HIPERFACE® interface
Single and multiturn encoder, e.g. SRS50, SRM50
Table 4.17 Suitable encoder types on X7
NOTE:
The usage of encoders not included in the range supplied by Moog requires
special approval by Moog.
y The maximum signal input frequency is 500kHz.
y Encoders 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 using 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 specied by the motor or encoder manufacturer. During this
process bear in mind the following boundary conditions:
y Always used shielded cables. Connect the shield at both ends.
y Connect the differential track signals A/B, R or CLK, DATA using twisted pairs.
y Do not cut the encoder cable, for example to route the signals via terminals in the switch cabinet.

NOTE:
The encoder supply at X7/3 is short circuit proof on both 5V and 11V
operation. The drive remains in operation enabling the generation of a
corresponding error message on evaluating the encoder signals.
