18.4.3 Utilisation >100 % regarding the max. speed
18.4.4 Utilisation >100 % regarding the thermal speed
18.4.5 Utilisation of the clutch >100 % regarding the torque
Warning!
The utilisation of the gearbox relative to the max. speed is xxx %. Thus the limit value of 100 % is exceeded.
Cause Effects Possible remedies
The gearbox is thermally and me-
chanically overloaded, i. e. it is over-
heated and damaged by too higher
speeds.
• This load is not permissible!
The gearbox is destroyed after a
short time!
• Reduce the entry of intended
gearbox input speed.
• Select motor with lower rated
speed.
• Select lower ratio.
• Select different mounting posi-
tion.
 Check of the speed load ( 337)
Warning!
The utilisation of the gearbox relative to the thermal speed is xxx %. Thus the limit value of 100 % is ex-
ceeded.
Cause Effects Possible remedies
The medium input speed of the gear-
box is too high.
• The gearbox is thermally over-
loaded.
• By the losses generated within
the gearbox, the gearbox will be
destroyed within a short time!
Select a different gearbox!
 Thermal utilisation ( 339)
Warning!
The utilisation of the clutch relative to the torque is xxx %. Thus the limit value of 100 % is exceeded.
Cause Effects Possible remedies
The torque transmitted via the clutch
is too high.
• The clutch between motor and
gearbox in standard mounting is
mechanically overloaded.
• The clutch is destroyed after a
short time!
Select different gearbox or motor in
direct mounting.
