321Eh Voltage Limit Function Maximum permissible PWM voltage (duty cycle) in millivolt. See also chapter Controller structure. Object description Index 321Eh Object name Voltage Limit Object Code VARIABLE Data type UNSIGNED32 Savable yes, category: application Access read / write PDO mapping no Allowed values Preset value 000186A0h Firmware version FIR-v2213-B1028181 Change history Description Also dependent on this value is whether the overmodulation of the voltage vector is used. If overmodulation is used, a higher torque can be achieved. The resulting voltage is no longer sinusoidal, which can result in harmonics and higher losses. Value in mV Overmodulation 1001…U o_low None; the voltage vector describes a circle. U o_low…U o_high The voltage vector describes a circle that is increasingly flattened on four/six sides in proportion to the set value. ≥U o_high Full; the voltage vector describes a square or a hexagon. U o_low The lowest voltage above which overmodulation occurs. Is calculated as follows (small deviations are possible depending on the hardware): Operating voltage*0.95 U o_high The maximum overmodulation occurs above this voltage. Is calculated as follows (small deviations are possible depending on the hardware): With two-phase stepper motors: operating voltage*1.128 With three-phase BLDC motors: operating voltage*1.05
