11.2.3.1 Feedback
11.2.3.1.1 ROD (AquadB) 5V (X5, X1)
A 5V incremental encoder (AquadB) can be used as standard motor feedback (primary and
secondary, (➜ # 75)). Every time the 24V auxiliary voltage is switched on, the amplifier need
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.
Vertical load can fall!
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 wake&shake with vertical load (hanging load).
The power supply for the encoder and thermal control in the motor is connected to X1. If lead
lengths of more than 50 m are planned please consult our customer service.
Frequency limit (A, B, N): 1.5 MHz
Type FBTYPE EXTPOS/Gearmode ENCMODE Remarks
AquadB 5V 13 3 0 MPHASE from EEPROM
AquadB 5V 19 3 0 MPHASE with wake&shake
Switch on supply voltage for the encoder at X1: set ENCVON to 1
