2.6 Balancing the field supply unit and the e.m.f. controller
When matching the field supply unit to the system conditions, differences in the proce- dures adopted must be taken into account; these different procedures result from the op- erating mode used. Only the work of that section has to be performed which deals with the operating mode actually used in your system!

Switch ON power; start drive. |

DANGER: System components now energized! |

Drive should run up to 10 % of the speed. |

12516 = increase slowly!
Internal reference value is increased; scaling: 20000 corresp. to 100 % speed or motor voltage, defined with P 501.
Measure motor voltage with the U ARM AC signal by changing between MODE ACT and PAR; with a value set with P 501, it must remain constant, or must not exceed this value if 12516 = 20000.
The motor voltage must not exceed the recommended motor voltage; see General notes at the beginning of this chapter.
Measure speed with manual tacho;
check rated speed when an analog tacho is being used; if necessary, correct with R9, R48 or R2716.
12516 = 0
Switch OFF power, thus stopping the drive!
