Drive module settings
Note: The parameter settings mentioned below apply to ACS850 Standard Application
Program.
It is recommended to set parameter 99.05 MOTOR CTRL MODE to DTC and to
•
adjust parameters 20.12 P MOTORING LIM and 20.13 P GENERATING LIM to limit
the maximum power. The calculated braking power can also be used as the
parameter value of 20.13 P GENERATING LIM.
When brake chopper is used, set parameter 48.01 BC ENABLE. This activates the
•
chopper when the DC voltage is high. Also the parameter 47.01 OVERVOLTAGE
CONTROL must be disabled from all of the converters separately.
All converters must be in the READY state before starting. See section READY
•
signals for instructions on how to connect the READY signals.
Switch on the possible DC contactors based on Table 1 after all of the DC links are
•
charged and the converters are in the READY state, i.e. when the power is on and
no faults appear.
