connection
Note:
The CDD3000-HF drive controller drives are protected
against shorting and ground faults at the terminals when in
operation. In the event of a short-circuit or ground fault in the
motor cable, the power stage is disabled and an error
message is delivered.
Attention: Do not confuse the motor and unit ends of the motor
phases U, V and W!If the motor phases are incorrectly
connected, the CDD3000-HF drive controller will lose control
over the motor and the motor may buck or accelerate
uncontrollably (“run away”). The entire system may be
damaged as a result! There may consequently also be
danger to human life.
Caution - Danger to life: Do not touch the motor terminals! There
may also be dangerously high voltages present
at motor terminals U, V and W in the “power
stage off” condition!
