Word data type “Torque”
A device-internal standardization conversion is performed for the torque. The stand-
ardization of a reference torque corresponds to that of a reference current (see
“Word data type: Current”). If the machine is operated with a rated flux value, a
reference torque corresponds to a reference current.
The specified equation for reference current and reference torque applies to opera-
tion with the rated flux value. This must be considered when a machine is operated
in the field weakening range.
The device-internal standard must be considered when current or torque variables
are used.
Data type “Long”
The “Long” data type can be used for frequency and position variables.
Frequencies use the internal representation of the frequency inverter
(xxx Hz / 4000 Hz) * 2
31
.
Examples:
50.00 Hz  (50.00 / 4000.00) * 2
31
= 0x01999999
-80.00 Hz  (-80.00 / 4000.00) * 2
31
= 0xFD70A3D8
The position information depends on the settings of the Motion Control Systems (see
“Positioning” application manual).
