BECKHOFF AX2500 - Manual (Page 55)

8.13.6 Incremental Encoder (X4)
An incremental encoder can be used as standard motor feedback.
Every time the 24V auxiliary voltage is switched on, the amplifier needs start-up informa-
tion 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 ampli-
fier's EEPROM.
The thermostat contact in the motor must be connected to X2 (see p.52) or X5 (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.
Frequency limit (A, B): 1.5 MHz
Encoder type FBTYPE Remarks
RS422 5V 9 MPHASE from EEPROM
RS422 5V 8 MPHASE with wake & shake
Don't use this feedback type with vertical load (hanging load).
