Chapter 10 - ACS 6000ad Start-up
Before idle running the motor, all preparatory works such as
inspections, measurements and I/O signal tests must be done. That
means, all actions described in the previous chapters should be done
and possible defects found must be eliminated. No alarms are allowed
to be active, neither in the ACS 6000 nor in related switchgear feeders.
10.1 Motor Idle Run
Check that the motor is ready for start (aligned, coupling is OK,
necessary lubrication is OK etc) and that starting the motor does not
cause any danger.
It is recommended that the driven equipment is discoupled from the
motor when the first start is performed if there is a risk of damage to the
driven equipment in case of incorrect rotation direction of the motor.
10.1.1 First Start-up with No Load
When doing the first start one should keep in mind that in order to
prevent the unnecessary rushing of the motor, all limits should be set to
safe values. If there is no certainty that phase order of the motor and
positive direction of rotation on the speed encoder coincides, there is
the possibility that first start ends with rushing of the motor (direction of
rotations are different).
To avoid the possible motor rushing during the first start, make the
following precautions:
• Check phase order between the inverter and motor.
• Use DC magnetizing mode by setting parameter 131.01 to value
CNST DC MAGN.
• use encoderless operation mode (parameter 111.02 set to TRUE).
See ACS 6000AD TC SW (Torque Controller Software) Commissioning
Manual for detailed instructions !
Before the first start see Chapter 13 - Speed Controller Tuning section
13.1 for preliminary tuning of speed controller.
