NOTE:
The encoder supply on 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.
4.13.3 Connection for high-resolution encoder
The interface X7 enables evaluation of the following encoder types.

Encoder/ SSI
Sin/Cos encoder with zero pulse
e.g. Heidenhain ERN1381, ROD486
Heidenhain Sin/Cos encoder with EnDat interface
e.g. 13 bit single-turn encoder (ECN1313.EnDat01) and 25 bit multi-turn encoder
(EQN1325-EnDat01)
Heidenhain encoder with digital EnDat interface
Single- or multi-turn encoder
Sin/Cos encoder with SSI interface
e.g. 13 bit single-turn and 25 bit multi-turn encoder (ECN413-SSI, EQN425-SSI)
Sick-Stegmann Sin/Cos encoder with HIPERFACE® interface
Single- and multi-turn encoder, e.g. SRS50, SRM50
Table 4.12 Suitable encoder types on X7
NOTE:
y
The usage of encoders not included in the range supplied by Moog
requires special approval by Moog.
y
The maximum signal input fr
equency is 500 kHz.
y
Encoders with a power supply of 5 V ±5 % must have a separate sensor
cable connection. The encoder cable detects the actual supply voltage
at the encoder, thereby compensating for the voltage drop on the cable.
Only use of the sensor cable ensures 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:
y
Always used shielded cables. The shield is to be connected at both ends.
y
Connect the differential track signals A/B, R or CLK, DATA to each other using twisted pairs.
y
Do not split the encoder cable, for example to route the signals via terminals in the switch
cabinet.
