Connection of feedback system
Over two hardware variants, the axis modules support the following feedback systems
(motor encoders) for servo control:
ƒ The E70ACM...R types support resolvers.
– On the X7 connection (A/B), 9−pole Sub−D socket
ƒ The E70ACM...E types support SinCos encoders
– On the X8 connection (A/B), 15−pole Sub−D socket
In the case of double axis modules, the hardware variant is designed in the same way for
both axes. Operation with different encoder types on one double axis module is not
possible.
At the motor encoder terminal (X7/X8), a PTC sensor can also be connected and evaluated
instead of a KTY sensor. A correct setting of the sensor type for motor temperature
monitoring is required (see reference manual).
Ensure an electrically protective separation of the KTY or PTC sensors from the motor
voltage potential:
{ Danger!
Hazardous electrical voltage
In the event of an error, control terminals can carry a hazardous electrical
voltage due to unsuitable KTY or PTC sensors.
Possible consequences:
ƒ Contact may result in fatal injuries.
Protective measures:
ƒ Only connect motors with safely separated KTY or PTC sensors.
