The brake choppers are already included in the Compact PLUS rectifier
units and converters. Only a suitable external braking resistor has to be
connected up, if required.
See also Chapter 11.7.
You will find preassembled encoder cables in Catalog DA65.11,
chapter 3. Please note that different encoder cables are required for
encoders and multiturn encoders. If the wrong encoder cable is used
for one or the other, fault F051 (during operation) or alarm A018 or
A019 is generated.
The encoder cable must only be connected and plugged in when the
converter is disconnected from the supply (24 V and DC link). Damage
to the encoder could result if this advice is not heeded. This especially
concerns the multiturn encoder EQN1325. Encoder or encoder cable
faults can result in incorrect field orientation and therefore in
uncontrolled axis movements.
