Incremental Encoder (X5)
An incremental encoder can be used as standard motor feedback.
Every time the 24V auxiliary voltage is switched on, the amplifier needs start-up information for the
position controller (parameter value MPHASE). Depending on the feedback type either wake&shake
is executed or the value for MPHASE is read out of the amplifier's EEPROM.
The thermal control in the motor is connected to X1 (see p.52) or X2 (see p.50).
If lead lengths of more than 50 m are planned and for questions concerning the power supply of the
encoder, please consult our customer service.
AGND and DGND (connector X3) must be joined together !
Frequency limit: 1.5 MHz

MPHASE with wake & shake
With vertical load the load could fall during wake&shake, because the brake is not
active and torque is not sufficient to hold the load. Don't use this feedback type
with vertical load (hanging load).
