4.4.24.3.2 Display in the ru parameters
If a value not equal to zero is parameterized in pn87[1] blockage mode->warning,
bit blockage warning is displayed in ru02 and ru03.
Blockade warning bit is set and no higher priority message is
active
Blockade warning bit is set
Whether 7: warning is also set in the statusword st00 or 0x6041 when the block-
ade warning bit is set can be defined via the object pn28 warning mask.
Monitoring of the load
Parameter ru80 relative load is used to display the load of the entire drive system
consisting of inverter, motor and application against torque and thermal limits.
No automatic reaction can be made dependent on the load display.
In the previous software versions, the rated torque was predefined by the drive.
Object pn88 now allows you to choose between different options for defining the
rated torque.
Configuration of the load display:
Standard display in ru80:
ru50 / ru51 > 100% => ru80 = ru24 actual torque
ru50 / ru51 ≤ 100% => ru80 = ru24 / ru50 (or ru51)
Display is configured by the settings in bit 2..7
Inverter limits are not consisered
Reference: 100% = current torque limit ru50 / ru51
(= limiting characteristic + parameterized torque limits
in the cs parameters + effective current limits)
Parameter pn88[2] application torque limit has no in-
fluence on the display in ru80
100% = pn88[2] constant torque limit
=> Application torque limit
the thermal load is not considered
Up to the rated speed, the reference for the actual
torque is dr09 rated torque, then the thermal perma-
nently available torque is reduced according to a 1/x
function, independent of the motor type . (Thermal
load)
